Perfluoroelastomers are terpolymers of monomers in which all hydrogen atoms have been replaced by fluorine 다운로드. These compounds combine the resilience and sealing force of an elastomer with the chemical inertness and thermal stability of PTFE.

Characterised by its exceptional chemical resistance and thermal stability for temperatures ranging from -25°C to in excess of 320°C 마이크로소프트 익스플로러. Application areas where the compound is often used: Chemical processing, Pharmaceutical and food industries, Oil and gas, Hydrocarbon processing, Semiconductor fabrication, Lacquer, print and coatings, Aerospace and Power generation 안 캠코더 다운로드.

General purpose Perfluoroelastomer (FFKM) O-rings are commonly stocked, however the sizes are somewhat limited and are usually inch based O-ring sizes (BS1806/AS568A) nero burning rom. We offer washer and gasket products in FFKM, however these would be considered a special order. FFKM is the most expensive elastomer family and usually is only used for applications where there is no other solution possible 무료 엑셀 다운로드.
