Polytetrafluoroethylene filling material


Product Features


Types of fillers


Glass fiber

Good abrasion resistance.

Glass fiber+Graphite

Good cold flow resistance and abrasion resistance.

Glass fiber+Molybdenum disulfide

Good abrasion resistance, cold flow resistance and electrical insulation.


Early wear and friction coefficient is small, heat conductivity is good.


The abrasion resistance, hardness and compressive strength are improved, and the thermal conductivity is good.


Cold flow resistance and load characteristics under high temperature and high load are good.

Carbon fiber

Wear resistance in water, high temperature, high load characteristics and bending strength are good.


Note: In addition to the above-mentioned production of other fillers, please choose to use according to the purpose of use.
