Fluorocarbon (FKM, Viton) / 氟橡膠

Fluorocarbon is a well-known high performance rubber. It has excellent resistance to high temperature, ozone, weather, oxygen, mineral oil, fuels, hydraulic fluids, aromatics and many organic solvents and chemicals. In addition to the standard Viton® compounds, we can supply parts made by Viton® 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.

Service
Temperature
For general type Viton® the service temperature is better limited to approximately from -26 C (-15 C) to 232 C (450 C) in static applications, 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 applications, it is suitable between -15 C and 200 C. For GLT-type the low temperature can be down below -40
C.

Hardness
For general Viton® types the hardness is from 50 to 90 Shore A. For others type 60 to 90 Shore A are
appropriate.

Color
Now black, brown, green, white, rust, yellow, blue are available, or any assigned color from
customers.

Application

Because FKM has excellent resistance of high temperature, oil, solvent, flame, chemicals and weathering, it is usually applied in automotive, chemical processing, aerospace and many other industries. Viton GLT has a more broad usable thermal range of -45 C to +275 C and outstanding in aggressive HTS-type oils, applied in aerospace applications. Viton ETP is usually applied in the chemical industrial field.
