PTFE wear agents can improve the surface properties and bulk properties of rubber, such as adding 5%-8% (mass fraction) of PTFE micronized powder to silicone rubber, nitrile rubber, fluoroelastomer, EPDM rubber and polychloroprene, etc. PTFE wear agents can improve the frictional properties, wear properties and demolding behavior of the main polymer and improve the crushing strength of rubber without significant damage to the elastic behavior of rubber, which can reduce rubber tearing caused by the demoulding process.

Rubber PTFE abrasion inhibitor characteristics:
1, Improve plastic processing fluidity and demolding performance; reduce torque, reduce equipment wear, easy mold filling, and reduce product defect rate.

2, Significantly reduce the coefficient of friction, improve the smooth performance, improve the surface gloss, enhance the surface silk touch, improve the scratch resistance and anti-static auxiliary effect.

3, Improve flame retardant performance, reduce smoke density, improve the impact strength and surface gloss of flame retardant (high filling) materials

4, has good stability and non-migration.

The main components of rubber PTFE wear agent: PTFE micropowder, rubber protective wax.

Effects:
1, It can improve the fluidity of plastic processing, reduce the torque and mold filling capacity.
2, Improving surface gloss, eliminating surface defects caused by adding filler and reducing defective rate.
3, Speed up the product extrusion speed, greatly reduce the defective rate, increase the amount of filler in the halogen-free cable material, and reduce the production cost.
4, Reducing the processing temperature of the products and eliminating the decomposition of raw materials caused by high processing temperature.
5,  Significantly reduce the surface friction coefficient of the product, improve wear resistance and demoulding performance, ideal additive for high-speed packaging films, and reduce heat and smoke emissions.
6, It can reduce the exothermic rate of cable combustion and is a good synergist for the production of low-smoke and halogen-free cables.
7, Its polymeric structure overcomes the shortcomings of traditional silicone oil.
