Ⅲ.Teflon die pressing bar
Teflon die pressing bar is made of polyfoln by means of die pressing in normal temperature and sinister roasting.
1.Service application:
It is used to make bearing strip, sealing and lubricant and electric insulation parts of all sorts of frequency.
2. Appearance:
The texture of Teflon die pressing bar is uniformity and the surface is skinpassing not permitting the shortcoming of cracking, air bubble delamination and mechanical damage.
3.Physical mechanical property:
