Nitrile, NBR

Hydrogenated nitrile, HNBR

Fluoroelastomer, FKM

TFE-P (Aflas© )

Perfluoro-Elastomer, FFKM

Good media resistance in
mineral oils and fuels, low gas penetration depending on ACN-ratio, Good cold flexibility, good
price-performance-radio as compared to high-performance elastomers

NBR-derived material with optimized media resistance in
mineral oils and chemicals, higher temperature resilience, weather-resistant,
good mechanical solidity and abrasion resistance.

FKM materials are characterized by high temperature
resilience and chemical stability, great resistance in mineral oils,
lubricants, aliphatic, chlorinated and aromatic hydrocarbons.

Aflas©compounds offer resistance to oils, lubricants and
some fuels approaching that of fluoroelastomer dipolymers, excellent
resistance to steam, amines, hydrogen sulphide (sour gas), and lye.

Simriz© (FFKM) is a high-performance elastomer, offering
a high chemical resilience similar to that of PTFE, but adding elastomer
advantages, extremely media and temperature resilient.
