FFKM Parts Chemical Resistance

Perfluorinated rubber (FFKM) components resist corrosion from more than 1,600 different chemicals, solvents and plasmas. Our products demonstrate superior performance in corrosive process environments. Whether faced with acidic, alkaline, amine, plasma or ultra-pure deionized water, manufacturers can effectively improve the sealing effect by selecting the most suitable parts for the specific application. We offer components in a wide range of compound formulations designed to optimize performance and ensure optimal performance across a wide range of chemicals and temperatures. 

Minimal Swell

Chemically induced swelling can cause O-rings and sealing components made of other elastomers to extrude out of seal grooves, resulting in seal failures. Materials such as FFKM (fluorinated elastomers) have excellent chemical stability and high temperature resistance, and generally have a low coefficient of expansion. This allows FFKM to maintain its size and elasticity in high temperature and pressure environments, providing reliable sealing performance in demanding sealing applications. They have proven to be a cost-effective solution in situations where seals with maximum resistance to harsh chemical environments and high temperatures are required.

Heat Resistance

Heat Resistance


The excellent thermal stability and chemical resistance of perfluorinated elastomer components is attributed to the strong action of carbon-fluorine bonds in the perfluorinated chain.

Minimize wafer contamination

Minimize wafer contamination


Perfluorinated rubber (FFKM) is used as a seal on wafer processing equipment due to its superior resistance to chemicals, including reactive plasma and extreme temperatures up to 330°C.

Rapid Gas Decompression

Rapid Gas Decompression


The fast gas decompression performance of FFKM (fluorinated elastomer) seals is a key feature in high-speed gas decompression applications.

Outgassing Performance

Outgassing Performance


In wafer processing, sealing and degassing performance is very critical, because the presence or release of any gas can have a serious impact on the quality, accuracy and production efficiency of the wafer.
