PFA GranulesWhat's the effect?PFA resins are relatively new melt-processable fluoroplastics. PFA particles melt bonding enhanced, solution viscosity decreased, and the performance of PTFE compared with no change, can be directly processed into products using ordinary thermoplastic molding methods.

pfa particleshas a melting point of about 580F and a density of 2.13- 2.16g/cc (grams per cubic centimeter). PFA is similar to PTFE and FEP, but above 302T, the mechanical properties are slightly better than FEP, and can be used at temperatures up to 500F, and its chemical resistance is equivalent to PTFE. The product forms of PFA are granular products for molding and extrusion, powder products for rotational molding and coating, and semi-finished products are films, plates, rods and pipes.

The PFA resins distributed in the U.S. market include the Teflon brand of DUPOut, the Neoflon brand of Daikin, the Hthen brand of Ansimont, and the Hostafl brand of HOechst Celanese. The use of PFA is similar to that of FEP.

pfa particles are mainly used in the production of corrosion-resistant parts, anti-wear parts, seals, insulation and medical equipment parts, high-temperature wires, cable insulation, anti-corrosion equipment, sealing materials, pump valve bushings, and chemical containers.
