PTFEkomposiitteja

PTFEkomposiitteja are composite materials that combine polytetrafluoroethylene (PTFE) with other reinforcing or filler materials. PTFE, also known as Teflon, is a fluoropolymer renowned for its exceptional non-stick properties, low friction coefficient, chemical inertness, and high temperature resistance. By incorporating various additives, the inherent properties of PTFE can be modified or enhanced to suit specific application requirements.

Common reinforcing agents include glass fibers, carbon fibers, graphite, bronze, and ceramics. Glass fibers improve mechanical strength and stiffness, while carbon fibers enhance wear resistance and electrical conductivity. Graphite and bronze are often added to reduce friction further and improve wear characteristics, particularly in bearing and sealing applications. Ceramic fillers can increase stiffness and thermal stability.

These composite materials find widespread use in industries demanding high performance and durability. Applications include seals, gaskets, bearings, bushings, valve components, and electrical insulators. Their resistance to aggressive chemicals makes them suitable for the chemical processing industry, while their low friction and wear resistance are valuable in automotive and aerospace engineering. The specific composition of PTFEkomposiitteja is tailored to optimize properties such as load-bearing capacity, thermal expansion, and electrical insulation for each intended use.
