PTFE micropowder can improve the surface and volume properties of rubber, such as silicone rubber, fluorine rubber, EPDM and polychlorobutadiene, adding 5% of PTFE micropowder can improve the friction properties, wear resistance and demoulding behavior of the main polymers, improve the breaking strength of rubber with no obvious damage to the elasticity of rubber, which can reduce the tearing phenomenon of the rubbers during the demouldingg process.
