Polytetrafluoroethylene/PTFE is free-flowing white powder and is produced by the atomic energy technology. It not only keeps all the original excellent properties of PTFE such as high stability, strong acid, alkali, high temperature and low temperature resistant,  

excellent lubricity, non-sticky performance, etc,but also it has many special properties such as no self-cohesion, no electrostatic effect, 

low molecular weight, etc,as additives for other materials, endowed with the properties of low surface energy and other fluorine polymer. 

It can mix with all kinds of base materials to greatly improve base materials’ lubricity, wearability, non-sticky performance, flame retardancy 

and can significantly improve the usability.
