The carbonized fiber yarn is treatded with graphite particles, and then is braided to from packing .Its surface is coated with an high -temperature-proof lubricant .It is able to bear high temerature and pressure, and helps prevent abrasion and volume loss to the packing rings .It can also help to minimize the effects of electrolytic pitting of the valve stem.

impregnated with PTFE dispersion .1t is inert toalmost all corrosive chemicals.When it is used for pumps,frictional heat is freely conducted to the stuffing box metal because of its excellent thermal conductivity ,and  thus no damage will be caused tothe packing 1t can replace PTFE  asbestos packing within wide service range. It can be used to seal  corrosive fluide except strong oxidizer acids, organic  solvents, fluids where contamination is not permissible for centrifugal

 ,plunger pumps,mixers valver, etc.

It is braided from high-performance Kynol (also named Novoloid or Phenolic )Fiber impregnated with PTFE lubricant. Good process –ability easy to cut and fit .Thermal stability ,low heat expansion :High dimensional stabilitly and superior pressure resistance even at elevated temperature.

A high performance packing that is well suited to applications where. graphite impregnaticn may not be acceptable. It is suitable for abrasive.media, and where ccntamination is not permitted. Outstanding chemical resistance particularly in acidic media excellent resistance to organic.solvents, oil and fuels.
