AST 4507 Pure Graphite with PTFE packing is woven of graphite PTFE yarn twisted through a mixture of PTFE dispersion resins and fine graphite powder, with a moderate amount of heat-resistant lubricant. Apart from its corrosion resistance, it has thermal conductivity and self-lubricating properties, and is suitable as dynamic sealing in conditions with media flow of high Linear velocity (about 16m/s).
