A dark brown high performance polymer containing a unique self- reinforcing polymer structure, developed specifically for critical semiconductor applications. The high purity of the polymer combined with the absence of any fillers makes this polymer suitable for processes involving lower feature sizes. This material has a low coefficient of thermal expansion, low compression set and has an extremely low etch rate in aggressive plasma environments. Key Attributes - Exceptionally pure - does not contain any fillers which may cause particulation problems. - Outstanding plasma resistance - ideal for Chlorine, Fluorine & Oxygen chemistries. - Exceptionally low plasma etch rate - Low thermal expansion - Retro-fits existing O-ring grooves (including FKM & FFKM grooves) - Low permeation - Low out-gassing - Low adhesion (reduced sticking) - Low friction, high strength and high modulus make K13X ideal for constant force dynamic applications. Typical Applications - Dynamic seals - Static seals - Wafer-handling products
