In chemical fields, pump valve leakage always like a "time bomb" hanging over enterprises! The strong corrosion of 98% concentrated sulfuric acid, the permeation of hydrofluoric acid, and the emission of VOCs... these problems make traditional pump valves become short lifespans, frequent leaks, and frequent accidents under high-intensity operating conditions. However,PFA resin, as an excellent fluoropolymer, possesses superior corrosion resistance, chemical resistance, and temperature resistance, and is widely used as a lining in chemical, food, new energy, and other industrial fields.
Lithium batteries:
Electrolyte reaction vessel lining (to prevent metal ion contamination)
Food processing:
Lining for high-temperature frying equipment (non-stick, no toxic release substances)
Electronics:
PFA lined pumps and valves in wet electronic chemical production
Chemical Industry :
Lining of Strong Acid (Sulfuric Acid, Hydrofluoric Acid) Storage Tanks
Fluid transportation:
PFA resin for pump valve lining in transferring corrosive and high temperature media.
