Tecnoflon® FKM & PFR FFKM

Sealing Solutions for Extreme Environments

Tecnoflon® Fluoroelastomers (FKM) and Perfluorelastomers (FFKM) are highly resilient synthetic rubbers that retain critical properties in chemically aggressive environments at extreme temperatures. Unlike traditional elastomers based on carbon-hydrogen or silicon-oxygen bonds, Tecnoflon® products derive their uniquely superior properties from the strength of carbon-fluorine bonds. Tecnoflon® FKM and FFKM are also highly resistant to UV light and ozone. 

Market Applications 

O-rings, seals and gaskets made from Tecnoflon® FKM and FFKM retain their shape, strength and flexibility at extreme temperatures. They exhibit low permeability to a broad range of fluids and chemicals, including gases, oils, lubricants, fuels, and additives. This makes them highly sought after for critical sealing applications in Semiconductor, Oil & Gas, Automotive, Chemical Processing and Healthcare industries where high purity and long service life are essential. Wearable electronic bands and straps benefit from soft and silky touch, premium haptics, durability and superior sweat and tear resistance of Tecnoflon® products.

Tecnoflon® FKM and FFKM Product Lines

Tecnoflon® FKM and FFKM products differ in fluorine content and curing methods, making it possible to tailor varying combinations of heat and chemical resistance. Both product families are easily processed using injection and compression molding. 

Tecnoflon® FKM fluoroelastomers consist of copolymers and terpolymers with a fluorine content of 66% and 68-70% respectively. They are available as base polymers (gumstock) or products formulated with ionic or peroxide curable systems. Base-resistant and low-temperature grades are available.
