Fusible polytetrafluoroethylene and poly perfluoroalkoxy resin what is the difference?
Generally used for corrosion resistant pipelines, containers, pumps, valves, radar, high frequency communication equipment, wireless electrical materials, etc..
Polytetrafluoroethylene (Teflon or PTFE), commonly known as the "king of plastic", is a polymer compound by the polymerization of tetrafluoroethylene, has excellent chemical stability, corrosion resistance, sealing, high viscosity lubrication, electrical insulation and good anti-aging endurance. Used as engineering plastics, made of polytetrafluoroethylene tubes, bars, belts, plates, films, etc..
It doesn't make any difference. It's just a different name.
PFA is polytetrafluoroethylene modified, temperature can reach 260 degrees, perfluoroalkyl resin, PFA resin is relatively new melt processable fluorine plastic. The melting point of PFA is about 580 degrees Fahrenheit, density of 2.13 - 2.16g/cc (g / cm3). PFA is similar to PTFE and FEP, but at 302 degrees above, mechanical performance is better than FEP, and can be as high as 500 degrees Fahrenheit temperature of use, its chemical resistance and PTEF. PFA's products include granular products for molding and extrusion, powder products for rotational molding and coatings, and semi-finished products including membranes, panels, rods and tubing.
