What is the chemical composition of Viton?
This family of elastomers comprises copolymers of terpolymers of tetrafluoroethylene (TFE), hexafluoropropylene (HFP) and vinylidene fluoride (VDF or VF2), vinylidene fluoride (VDF) and hexafluoropropylene (HFP) as well as perfluoromethylvinylether (PMVE) containing specialty polymers.
Are there different grades of Viton?
There are three major families of standard Viton fluoroelastomer: A, B, and F. The Viton A types are comprised of vinylidene fluoride (VF2) and hexafluoropropylene (HFP). The B and F types are made with vinylidene fluoride (VF2), hexafluoro- propylene (HFP), and tetrafluoroethylene (TFE).
Is FKM and Viton the same?
These rubber compounds give exceptional heat resistance with compatibility across many fluids or chemical exposures. The most commonly known name for these compounds is “Viton,”™ which has become the generic name for all FKM polymers and rubber compounds.
What is Viton coating?
10269 Viton® – Tool Sealant Mosites #10269 is a cream colored, high temperature Viton Fluoroelastomer coating that is used to seal against vacuum loss due to hairline cracks in composite tooling.
Is FKM Viton material?
Fluoro-Elastomer is usually referred to as FKM FPM or as VITON™ after the popular brand which produces it. You may see this rubber listed in different places with these different names, but they are all one and the same.
What is Kalrez material?
Kalrez® 1050LF is a carbon black-filled product for O-rings, seals, and other parts used in chemical process industries. It has good hot water/steam, and excellent amine resistance. Designed for low-temperature environments where significant chemical resistance is required.
What is Viton type A?
The Viton™ A-type family of fluoroelastomers are dipolymers comprised of hexafluoropropylene (HFP) and vinylidene fluoride (VF₂). They are used in a wide range of extrusion, injection molding, and solution coating applications, and some grades act as effective curing chemicals and metal adhesion promoters.
Is Viton A fluorocarbon?
Viton® is the brand name for fluorocarbon rubber polymers of the Chemours Company. This type of polymer is used extensively by ERIKS, however we do not claim or promote the use of any specific brands of polymers in our compounds.
What is the difference between Viton and EPDM?
Both are types of rubber polymers that are compounded for low compression set. Viton® rubber is a fluoro elastomer, whereas epdm rubber is ethylene-propylene-diene-monomer. The primary differences between Viton® and EPDM is in their chemical resistance and temperature ranges.
What is kalrez made of?
Because Kalrez® parts maintain their sealing integrity, you reduce your risk of environmental non-conformance. Kalrez® parts are made only by DuPont, a fully integrated manufacturer of Vespel® parts and shapes, Viton® fluoro elastomers and Neoprene rubber polymers, as well as perfluoroelastomer parts.
What is the difference between FKM and FFKM?
FFKM, or perfluoroelastomer, contains higher amounts of fluorine than standard FKM, and features higher temperature ratings, up to approximately 325°C. FFKM also has improved chemical resistance, with nearly universal chemical compatibility. The first commercially available FFKM seal was produced in the late 1960s.
Is EPDM the same as Viton?
What is the casting grade in ASTM A126?

What is the temperature of a Viton test?
Test temperature is 24 °C (75 °F), except where specified otherwise. For more information, visit Viton.com
What is the trade name for Viton elastomers?
Finding the correct material is important as the seal can degrade easily if the material is not compatible with the environment. Viton FKM is DuPont-Dow Elastomer’s trade name for fluorocarbon elastomers. Fluorocarbon elastomers exhibit excellent resistance to high temperature and low compression set.
What does an ASTM designation number stand for?
An ASTM designation number identifies a unique version of an ASTM standard. Active Standard ASTM A126 | Developed by Subcommittee: A04.01 Book of Standards Volume: 01.02
