Braided from shrink-proof synthetic fiber impregnated with PTFE, silicon-oil-free, which is oxidized polyacrylonitrile fiber. Compared to traditional carbon fiber packing, it is not brittle, can suited for high peripheral speeds and food industries. Oxidized fiber has high strength and good thermal conductivity, PTFE makes the packing have excellent self-lubrication, so this packing does not damage shafts and has long life.

Carbonized PAN fiber impregnated with PTFE dispersion containing graphite particles, PTFE and graphite makes the packing have excellent self lubrication.

Braided from strong carbon continuous yarns after softening, impregnated with proprietary lubricants and graphite particles, which fill voids, act as a break-in lubricant, and block leakage.
