Polytetrafluoroethylene teflon
rubber compound filling piece(PTFE)
1、Characteristic
The PTFE (i.e. F4 rubber compound pad), is
a new type airproof material,that takes the
Polytetrafluoroethylene and the high quality
synthetic rubber as parent metal,applies
with special production craft.It synthesized
the fine characteristic of polytetrafluoroethylene
and rubber respectively, makes the product
have outstanding anti-corrosive, thermostable,
non-toxic, the anti-glutinosity, and good
elasticity and the airproof quality.
