1.Properties:
- Outstanding
H-temperature resistance.
- Excellent resistance
to fuel,oil,acid and chemicals.
- Good resistance to
gas penetration and radiation.
- Besides,with all the
properties of general rubber.
- Outstanding
physical,electrical and mechanical properties.
- Can work in
harsh,thermal,chemical,and UV environments where general rubber can not .
2.Applications:
- Extensively used in
aerospace/aviation,automobile,petroleum and chemical,mechanical industry,and
construction,communication and concrete industry,etc.
- Mainly used as
sealents resisting H-temperature,fuel,oil,etc.,and as erosion-protection material,to make
O-ring ,oil,etc., diaphragm,gaskets,rubber bowl and valve core,etc..
