This product is a PFA resin by the extrusion method PFA tubing made of long-term use temperature of -80 ℃ ~ 260 ℃, high purity tubing, flex life is 100 times FEP tube. The tube is an ideal material for the semiconductor industry, and long flex life applications. PFA tubing also has excellent chemical resistance, corrosive liquid or gaseous media can be used as ducts, lined pipe. Tetrafluoroethylene and perfluoro propyl vinyl ether copolymer (PFA), polytetrafluoroethylene, also known as soluble, fully maintaining the excellent performance of PTFE, temperature -80∽260 ℃, having good mechanical, electrical insulation performance, outstanding heat resistance and low coefficient of friction, flame retardant, low smoke, weather resistance, also has good thermoplastic. PFA (commonly known as fusible polytetrafluoroethylene) maintained a PTFE excellent chemical stability, high resistance, low temperature properties, dielectric properties, self-lubricating, anti-adhesive, non-flammable and anti-aging properties. Its outstanding feature is the folding, good crack resistance, mechanical strength at high temperature is more than 1.6 times the PTFE.
