Plastic PTFE Processing Parts

PTFE Processing Parts:

The friction coefficient of polytetrafluoroethylene is only 1 / 5 of that of polyethylene, which is an important feature of perfluorocarbon surface. Because of the low intermolecular force between fluorine and carbon chain, polytetrafluoroethylene has no viscosity. Polytetrafluoroethylene has excellent mechanical properties in a wide range of temperature from - 196 ℃ to 260 ℃. One of the characteristics of perfluorocarbon polymer is that it is not brittle at low temperature. The density of PTFE is 2.14-2.20g/cm, almost no water absorption, and the equilibrium water absorption is less than 0.01%. Polytetrafluoroethyleneis a typical soft and weak polymer. The interaction between macromolecules is small, the rigidity, hardness and strength are small, and it will deform under the long-term stress.

Polytetrafluoroethylene is a typical plastic with cold fluidity, which is easy to creep under load. The creep of PTFE varies with compression stress, temperature and crystallinity. The higher the temperature is, the greater the creep is. When the crystallinity of PTFE is between 55% and 80%, the creep variable does not exceed 2%; when the crystallinity is below 55% and above 80%, the creep variable increases rapidly
