Fluorocarbon is a well- known high performance rubbers, especially it has excellent resistance to high temperature, ozone, weather, oxygen, mineral oil, fuels, hydraulic fluids, aromatics and many organic solvents and chemicals. Now we can supply rubber compound made by Viton® system gum like general type (A-TYPE, 66% fluorine) middle fluorine content type (B-, GBL-TYPE, 67~68.5% fluorine), high fluorine content type (F-, GF-TYPE,70% fluorine ), improving low temperature flexibility type (GLT-, GFLT) and excellent resistant to more chemicals and solvents– Viton® ETP Extreme.
For general type the service temperature is better limited to approximately from -26°C(-15°F) to 232°C(450°F) in static application, though the service temperature can arrive to 275°C at short time but up to 232°C the parts life will be shortened. In dynamic application it is suitable between -15°C and 200°C.
For GLT-type the low temperature can be down below -40°C.
For general type the hardness from 50 to 90 Shore A are available.
For others type 60 to 90 Shore A are appropriate.
Now black, brown, green, white, rust, yellow, blue are available, or any assigned color from customers.
Because FKM has excellent resistance of high temperature, oil, solvent, flame, chemical and weather, it is usually applied in automotive, chemical processing, aerospace and many industrial.
Viton GLT has more broad usable thermal range of -45°C to +275°C and outstanding aggressive HTS-type oils, applied in aerospace is a good choice.
Viton ETP usually applies in chemical industrial field.
Some fuels add several methanol, Viton F- and B-type are more usable than A-type especially F-type. Some lubricant add a few organic amide or amine, choosing peroxide curing system Viton will be better than bisphenol curing system
