AsahiGuard E-SERIES ™

What are the differences between AsahiGuard E-SERIES ™ and conventional AsahiGuard?
AsahiGuard E-SERIES ™ offers the same high performance characteristics as our former product line but does not contain perfluorooctanoic acid (PFOA), longer chain length-perfluorocarboxylic acids (PFCAs) or their precursors at or above detection limits.
What are the differences between AsahiGuard E-SERIES ™ and other water repellent products or materials?
Water resistance happens when surface tension of the solid surface is lower than liquid surface tension.
Fluorinated water/oil repellent agents made with perfluoroalkyl groups easily resist not only water but also highly osmotic liquids such as oil. This is because the perfluoroalkyl substituent group has extraordinarily low surface tension - much lower than water-based or oil-based stains. Since it has excellent durability as well, it is an agent that surpasses the level of other wax-based or silicone-based water and oil repellents.
What are the current products?
There are currently over 10 product types that include products for textiles and paper. In the future, we will further expand this product line. Please click here for details.
What are the characteristics of AsahiGuard E-SERIES ™?
AsahiGuard E-SERIES ™ does not include PFOA, PFOA-related substances, or their precursor materials at or above detection limits, which have been the subject of concerns over their effects on humans and the environment. In addition, it is a product with low environmental impact that has achieved the elimination of APEO and the reduction of impurities.
What is PFOA?
PFOA is used as an emulsifier for polymerization when producing fluoropolymers, and is also an impurity contained in trace amounts of fluorinated water and oil repellents. It is a substance that has been found to be present in the blood of humans and wildlife, and has been widely detected in the environment.
What are the risks associated with PFOA?
Since PFOA has the proclivity to accumulate within the body and has been subject to concerns over its toxicity, it has been undergoing a variety of tests in risk evaluations. At the time of the announcement of preliminary risk investigations by the U.S. Environmental Protection Agency (USEPA) and draft risk evaluation reports released in January 2005, the results of evaluations on the safety of PFOA with regard to the human body have not yet been clearly determined.
What is PFHxA?
CF3-CF2-CF2-CF2-CF2-COOH. Perfluorohexanoic acid.
AsahiGuard E-SERIES ™ is a copolymer using fluorinated monomers containing compounds with a carbon number of 6. The final chemical substance created after the polymers and monomers break down naturally is PFHxA (perfluorohexanoic acid). The toxicity and bioaccumulation potential of PFHxA have been confirmed to be significantly less than those of PFOS and PFOA.
What is PFOS?
Industrial synthesis procedures for fluorine compounds that are the key raw materials of fluorinated water and oil repellents include telomerization and electrolytic fluorination.
While the key raw materials of AsahiGuard and the AsahiGuard E-SERIES ™ are manufactured using telomerization, PFOS (perfluorooctanesulfonic acid) is a key raw material for products including fluorinated water and oil repellents that are manufactured using electrolytic fluorination. It is also a final decomposition product of PFOS-based water and oil repellents, whose manufacture has already been discontinued.
Why are fluorinated water and oil repellents able to repel water and oil?
Liquid-repellent properties are generated if the surface tension of a solid surface is lower than the surface tension of a liquid. The perfluoro alkyl group (Rf group) used in fluorinated water and oil repellents has the lowest surface tension among such substances, making it able to repel not only water but also highly-permeable liquids such as oil.
What are the applications of AsahiGuard E-SERIES ™?
AsahiGuard E-SERIES ™ can be used to treat not only textiles and paper, but also non-woven fabrics and leather. In terms of its applications, it has a wide range of uses benefitting many industries, including general clothing, sportswear, umbrellas, food packaging, paper, medical-related applications, automobile parts and filters, and still growing.

* Each of these excludes certain grades. Please inquire with us regarding details and conditions of use.
Uses of Fluon® PTFE
Although PTFE is the most mature fluoropolymer with over 60 years since its commercialization, new applications are still being found today since its outstanding features typical of fluoropolymers mean it offers all kinds of benefits.
Fluon® PTFE is used in the construction industry, the chemical processing industry, the automotive industry, the semiconductor industry, the electrical industry and the textile industry. It also has applications in machinery and is used as a wire coating. PTFE powder is used as an additive in other media such as plastics, elastomers, paint and greases to improve friction and non-flammability.
As well as PTFE in powder form, aqueous dispersions of PTFE are also available.
Filled PTFE compounds are another type of PTFE which are suitable for applications where improved creep resistance and minimum wear are required.
Uses of Fluon® PFA
Fluon® PFA has very similar properties to Fluon® PTFE and in addition Fluon® PFA is melt processable.
The majority of applications for Fluon® PFA are in the semiconductor industry in areas such as pipes, joints, wafer carriers and tanks of semiconductor manufacturing machinery and equipment.
In addition to applications in the semiconductor industry, the other two main areas of applications are office machinery/appliances and lithium ion battery packings. "
Uses of Fluon® ETFE
Fluon® ETFE, a copolymer of ethylene and tetrafluoroethylene, has excellent mechanical properties and radiation durability. Because of these properties Fluon® ETFE is used as wire insulation in robots, nuclear power plants and in precision instruments such as personal computers.
Fluon® ETFE Film and F-CLEAN® are films made from Fluon® ETFE. These films have applications such as release films, architectural films and greenhouses.
Fluon® ETFE powder is also available and is used in the chemical processing industry and the automotive industry. It is used to coat pipes and other metal parts by electrostatic coating or rotolining. It is also used in rotomolding. "
What are the uses of Fluon® LM-ETFE?
LM-ETFE is the evolved form of ETFE, developed independently by AGC. Its primary characteristic is that it has succeeded in achieving a lower melting point while improving its heat-resistance. This property is widely used in automobile parts, electric wire coatings, tubing and hoses, and containers. The AH series are used for multi-layer fuel hoses for automobiles that can meet the extremely strict environmental regulations of North America.
What are the molding methods for Fluon®?
Compression molding
This is the method most commonly used for molding Fluon® PTFE. This method is used because even if Fluon® PTFE reaches a temperature at or higher than its melting point, it has an extremely high melt viscosity. The resin is poured into a mold and compressed, then fired to fuse its particles to each other. After this, it is cooled to obtain the molded product. If molded products with finely detailed shapes or complex shapes are required, it can then be cut by machines to yield the final products.
Suitable grades: PTFE (molding powder), PTFE (filled compound)

Paste extrusion molding
This is another molding method used for Fluon® PTFE. It is used when fine powder is to be molded. The resin is combined with an auxiliary material (naphtha can be used) and pressed into a die, and by extruding it from the die, molded products in the form of tubes, pipes, or tapes can be yielded. Removing the auxiliary material content and firing will then complete the procedure.
Suitable grades: PTFE (fine powder)

Melt molding
Fluon® PFA, Fluon® ETFE, and other fluoropolymers that dissolve when reaching or exceeding their melting point can be molded using molding methods equivalent to those of other thermoplastic resins. Melt molding includes extrusion molding, injection molding, blow molding, transfer molding, rotational molding, and other methods, but all of them can be used with dissolved fluoropolymers. However, differences when molding them compared to other plastics include their high melting point which leads to higher molding temperatures, and their relatively high melt viscosity which results in slower molding speeds.
Suitable grades: PFA, ETFE, LM-ETFE

Coextrusion molding
In the past, coextrusion molding using fluoropolymers was considered impossible, due to their non-adhesive nature. However, the Fluon® LM-ETFE AH Series developed by AGC has made the use of this method possible. By casting another type of resin together with the AH Series in a single coextrusion die and then carrying out molding, a laminated molded product achieving excellent adhesion can be obtained.
Suitable grades: LM-ETFE AH Series

Powder molding
By using resin in powder form, molded products adhere to metals in the form of coatings and linings . Such products are ideal for the corrosion protection of metals.
Suitable grades: ETFE powder grades
Is there a grade of fluoropolymers with added fillers?
Yes. There is a wide lineup of filled compound grades for Fluon® PTFE. Many different levels of performance of PTFE characteristics can be achieved by incorporating various types of fillers, allowing them to be used for different purposes. Fluon® ETFE also has a wide lineup of grades that consist of mixtures with carbon black, carbon fiber, colored pigments and other reinforced fillers, which can be used in forms that provide added features such as conductivity, strength, and color identification.
Can fluoropolymer coating be performed?
Yes. Fluon® ETFE has a wide lineup of powder grades, which can be applied by rotational molding or electrostatic powder coating to produce coatings on metal that are several tens to several hundreds of μm thick. PTFE can also be used for enamel coating, so it can be used for a wide variety of applications most commonly represented by frying pan coatings.
What is the heat-resistance of Fluon®?
Fluoropolymers have extremely high melting points, in most cases reaching 200℃ or higher. Their continuous operating temperatures also range from 150℃ to 261℃, giving them the highest level of heat-resistance among plastics.
What is the chemical resistance of Fluon®?
It is inert with strongly-acidic or strongly-alkaline substances at high temperatures or high concentrations, and is also insoluble when exposed to solvents.
What is the ultraviolet light resistance of Fluon®?
The degradation of its performance in outdoor environments is extremely low, and it can be used for prolonged periods of time. When exposed to outdoor environments, materials are subject to effects including photodegradation and oxidation from sunlight, and expansion and contraction from changes in air temperature. Fluoropolymers have the property of being resistant to changes or degradation in such severe environments.
What is the radiation resistance of Fluon®?
Most resins which are formed by bonding between carbon atoms and fluorine atoms, such as PTFE, PFA, and FEP, generally decay when exposed to radiation and cannot be used in such environments. Fluon® ETFE, however, is a copolymer of tetrafluoroethylene and ethylene. Since ethylene causes cross-linking reactions when exposed to radiation, it will virtually not decay even if irradiated.
Applying this property, Fluon® ETFE is widely used in insulated electric wires requiring radiation resistance in addition to heat-resistance and steam resistance, in areas located near nuclear power plant reactors.
What are its dielectric constant, dielectric tangent, and electrical insulation properties?
It has high flame resistance and electrical properties that are acknowledged by the strict standards of various industries. The dielectric constant of fluoropolymers is the lowest among plastics, with essentially no changes due to frequency. Their volume resistivity is also at a level so high that it exceeds the limits of measurement.
What are its adhesive properties?
Fluoropolymers are actually non-adhesive and have the nature of being difficult to bond, but this has been achieved with Fluon® ETFE/LM-ETFE AH grades that can adhere to metals or resins. Please inquire with us regarding uses.
What are the safety properties of Fluon®?
If ingested
Well-known for their use as coatings for frying pans, the safety properties of fluoropolymers have been confirmed through experiments such as the following. A 25% portion of fine powdered PTFE was mixed in with food given to lab rats for 90 days. No poisoning or pathological/anatomical changes were noted. Fluoropolymers are chemically inert, and even if ingested orally will not be broken down or react and generate poisonous substances, but will be passed through the body.

If it combusts or is thermally decomposed
As indicated on the “Properties” page, fluoropolymers are plastics with an extremely high level of flame resistance. However, if exposed to high temperatures that exceed their melting points, it is known that they will begin to thermally decompose and generate decomposition products. In the case of PTFE (melting point: 327℃), decomposition will accelerate from around 400℃, and its decomposition products will be detectable. Substances such as tetrafluoroethylene and hexafluoropropylene will first be detected, followed by perfluoroisobutylene from around 480°C and then carbonyl fluoride gas at around 500°C. These decomposition gases are more or less toxic, with perfluoroisobutylene and carbonyl fluoride being extremely toxic. Although fluoropolymers are flame resistent, be aware that extremely toxic gases will be released if any large fires start around fluoropolymers.

Important points in processing
Although there is virtually no danger of the highly toxic decomposition gases noted above being released under normal fluoropolymer processing conditions, we have heard of cases where powdered substances were released. These are thought to cause so-called “polymer smoke fever” in the human body.
If fluoropolymer thermal decomposition products are inhaled for a long time (or a short time for highly-concentrated products), influenza-like symptoms could occur. This is referred to as “polymer smoke fever”. This condition manifests after an incubation period lasting a few hours, after which symptoms continue to weaken and completely disappear within 24 to 48 hours. There are virtually no lasting effects. Suitable air circulation in the processing environment is the most effective means toward preventing this kind of condition.
Although it is often handled only in small amounts or in situations where natural air circulation is sufficient for the environment where the processing equipment is installed, we recommend installing local ventilation facilities around processing equipment to ensure safety.
What is its safety for food-related applications?
Fluon® PTFE and PFA are compliant with the requirements described in the U.S. regulation 21CFR§177.1550 as indirect food additives. Fluon® ETFE is registered on the list of FCS (food contact substances) of the U.S. FDA, and has obtained an FCN number. Within Japan, it is also compliant with the Food Sanitation Act’s Ministry of Health and Welfare Notification No. 370.
* Each of these excludes certain grades. Please inquire with us regarding details and conditions of use.
What are the disposal methods for fluoropolymers?
Fluoropolymers are known to release toxic gases when they reach high temperatures. Please consult your local waste disposal rules onhowbest to dispose these fluoropolymer product waste materials.

Fluon® ETFE Film

Is Fluon® ETFE Film safe?
If ingested
Fluoropolymers are well-known for their use as frypan coating, and the following tests have been conducted to confirm their safety. A 25% portion of fine powdered PTFE was mixed in with food given to lab rats for 90 days. No poisoning or pathological/anatomical changes were noted. Fluoropolymers have chemical resistance, and even if ingested orally will not be broken down or react and generate poisonous substances, but can be pass through the body.

If it combusts or is thermally decomposed
PTFE, ETFE, PFA have a high level of non-flammability.
However when fluoropolymers are heated above their melting point they start to decompose and give off decomposition chemicals.
In the case of PTFE (melting point: 327℃), decomposition takes place at about 400℃ and decomposition chemicals can be detected.
Initially tetrafluoroethylene and hexafluoropropylene are detected, then perfluoro isobutylene is detected at about 480℃ and later carbonyl fluoride is detected at about 500℃.
These decomposition gases are toxic to some extent; in particular perfluoro isobutylene and carbonyl fluoride are highly toxic.
Although fluoropolymers are fire retardant, should a large scale fire take place, then toxic gases would be present and the necessary precautions should be taken.

Remarks regarding processing
Although there is little risk of such toxic decomposition gases at the usual processing temperature, it is known that a particle-like substance will be generated. This is considered to be the cause of the condition known as ""polymer fume fever"" to the human body.
The symptoms of the syndrome are similar to those of influenza. The heat decomposition gases from the fluoropolymers arise during processing whether it is short term or long term processing and so a high concentration of these gases may be evident. This is called ""polymer fume."" Although this condition has an incubation period of several hours and after some time the condition does gradually disappear, it disappears completely within 24 - 48 hours and no subsequent illness remains. In order to prevent polymer fume fever it is advisable to ensure suitable ventilation is installed in any processing environment.
Although natural ventilation may be adequate in many cases, depending on how the processing equipment is installed when handling small amounts of polymer, it is recommended that a local exhaust ventilation (LEV) system should be installed to guarantee complete protection from 'polymer fume fever'.
How should Fluon® ETFE Film be disposed of?
Fluoropolymers produce toxic gases when they are heated in high temperature. Please consult your local wastedisposal rules on how best to dispose these fluoropolymer product waste materials.
In what forms can we buy?
Master rolls, slit rolls, and flat sheets are available. Please ask us each grades' minimum order quantity.

Afluid™ IRX

Why can you achieve such outstanding stain resistance by adding such a small amount?
Because the polymer part that contains fluorine molecules that confer IRX’s stain resistance is dispersed thinly and widely over the outermost surface of the coating.
How much additive is needed to get an effect?
A compounding ratio of 0.5-1% is recommended, but in some cases a stain resistance effect can be seen at about 0.1%. Please confirm the most appropriate additive amount before proceeding.
Please tell me about the types of coating liquids that IRX can be added to.
It is compatible with hydrocarbon-based coating liquids (ketone, glycol, ester, acrylic-based, etc.). Please confirm before proceeding. Furthermore, solubility can be improved by raising the temperature to about 40°C.
Please tell me how to improve durability even further.
Instead of air-curing, durability can be improved by curing in a nitrogen atmosphere.
