Fluorine resin products

PTFE (Poly Tetra Fluoro Ethylene), a type of super engineering plastic, is a fluorine resin generally called Teflon. It excels in heat resistance and has the lowest friction coefficient among plastics.
By adding various types of fillers to PTFE, such as glass fibers, carbon, and graphite, it is possible to produce products having excellent abrasion resistance, such as backup rings, slipper seals, V-rings, and V-packing seals.
