ANTIFRICTION POLYMERIC MATERIAL Russian patent published in 2003 - IPC

FIELD: polymers. SUBSTANCE: invention relates to production of antifriction polymeric materials. Antifriction polymeric material is made of the composition containing polytetrafluoroethylene and carbon-containing addition. As addition composition contains 1-10% fullerene carbon black powder or fullerene carbon black powder after extraction of fullerenes from it mass containing up to 50% of the parent fullerenes content of the composition mass. Invention provides preparing antifriction material combining low friction coefficient and high resistance to wear. EFFECT: improved and valuable properties of material, low cost of product. 1 cl, 1 tbl
