AF101-BR85 (genuine VITON*) FPM F109- brown( bisphenol cross linked)

General

F109-BR85 is a brown Fluorocarbon elastomer, commonly referred to as VITON* and FPM. FPM materials have a very high resistance to hydraulic fluids, chemical and a number of organic compounds and operate in temperature between -20 to +210°C. F109-BR85 is recommended for applications where its outstanding resistance to heat, chemicals weathering and ozone is required.
