Polytetrafluoroethylene fiber is packed with tetrafluoroethylene fiber as skeleton material, then woven with polyvinyl fluoride
emulsion. The filling has good chemical stability for strong corrosive medium such as acid, alkali and solvent. The temperature
range is wide and the friction coefficient is low. The pump, concentrated nitric acid plunger pump has good effect, especially in
Methylamine Pump with a small amount of crystal, and its service life is more than 2 times of asbestos impregnated tetraethylene
packing
