New Materials Based on Polytetrafluoroethylene and Modified Filling Materials in Mining Industry

Abstract

Abstract Investigation into properties of polymer composite materials based on polytetrafluoroethylene and natural zeolites modified with F-42 and F-2M fluoroplastics is proposed in the present paper. It is shown that different zeolite modification techniques govern performance of composites. In the mechanical activation process a small amount of F-2M bearing filler improves Young’s modulus and relative tensile elongation of composites under rupture by 20-50%. Introduction of F-2M modified filler in amount of 5% by weight provides 380-fold increase in durability as compared to polytetrafluoroethylene. F-42 fluoroplastic used as a modifier of zeolite enables to gain 2-2.75-fold lower plastic yield of composites. The present research findings make it possible to consider the composites as promising materials in the mining industry.
