The packing is made of polyacrylonitrile fiber, heated into carbonized fiber, which is woven into packing after impregnation in PTFE dispersion containing graphite particles. It is used as dynamic sealing in the presence of media of weak acid or alkaline, or media that contain few grains of solid particles.

The packing is braided from Aramid fiber, a strong organic substance, impregnated with PTFE dispersion and lubricant. It is suitable as dynamic sealing in places where media contain solid particles.

The packing is braided from graphite PTFE and enhanced with aramid yarn on the corners. It has better lubricity and thermal conductivity. It is used in high pressure working environments.

The packing is woven of strong carbon fiber softening treatment and impregnation with the mixture of fine graphite powder, PTFE dispersion and lubricant. Being strong, static and heat conductive, It is widely used with revolving or reciprocating pumps, where media of chemical corrosion and grains of particles exist.
