(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.
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.
For general Viton® types the hardness is from 50 to
90 Shore A. 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, 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.
