PTFE graphite packing

PTFE graphite packing (F4 black textured fill):
PTFE dispersion resin and graphite powder and an appropriate amount of high-temperature lubricant for the material, made ​​of PTFE yarn containing graphite, and then woven into packing. Apart from this packing PTFE has the chemical resistance and other characteristics, there is good thermal conductivity and self-lubricating. Therefore, this dynamic sealing packing used, you can adapt to high speed (about 16m / s).
Scope
Maximum temperature: 280 ℃ Max pressure: 4.0MPa PH value 0-14
