Tribotechnical composites based on polytetrafluoroethylene (PTFE) and secondary fluoropolymeric raw material

Purpose and Scope

Polymer composite material based on polytetrafluoroethylene (PTFE) and secondary filler is used in friction knots of piston compressor machines and sealing elements.

 Main Characteristics and Essence

The technique of obtaining antifriction PTFE-composite with the use of secondary filler of required physical, mechanical and tribotechnical properties is developed.


The developed material has high chemical resistance, insolubility in most known solvents, low coefficient of friction, maintains performance over a wide temperature range. It has a low cost, and it is environmentally friendly.

Intellectual Property Protection Status

Two patents of Ukraine are obtained for utility model.

Market Demand

These composites are indispensable in the nodes of friction of modern machines and mechanisms.

Readiness for Operation

The developed material is implemented in industrial enterprises.
