Introduction to 1. PFA:
1. PFA is a small amount of perfluoropropyl perfluorovinyl ether andTeflonof the copolymer. The melt adhesion is enhanced, the solution viscosity is reduced, and the performance is unchanged compared with PTFE. This kind of resin can be directly processed into products by ordinary thermoplastic molding methods.
2, long-term use temperature -196-260 degrees, has excellent chemical resistance, corrosion resistance to all chemicals, the friction coefficient is the lowest in plastics, there are good electrical properties, its electrical insulation is not affected by temperature, known as "plastic king.
3, its chemical resistance and PTFE similar,vinylidene fluorideOkay.
4, its creep resistance and compression strength are better than PTFE, high tensile strength, elongation up to 100-300%. Good dielectric properties, excellent radiation resistance, flame retardant V0 level.
5, non-toxic: with physiological inertia.
Characteristics of 2. PFA board
The PFA sheet has 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.

3. PFA board is how to make
The product forms of PFA are used in the form of granular products for molding and extrusion, powder products for rotational molding and coating, and semi-finished products include films, plates, rods and pipes. The use of PFA is similar to FEP.
4. formability of PFA sheet
1, crystalline material, moisture absorption is small. Can be processed into products using the usual thermoplastic processing methods
2, poor fluidity, easy to decompose, decomposition of corrosive gas. It is advisable to strictly control the molding temperature not to exceed 475 degrees, the mold should be heated to 150-200 degrees, and the resistance of the gating system to the material flow should be small.
3. Translucent pellets, injection molding, extrusion molding. The molding temperature is 350-400 degrees, and more than 475 degrees is easy to cause discoloration or bubbles. And note that demoulding will be more difficult.
4, because the molten material has a corrosive effect on the metal, long-term production, the mold needs to be plated with chromium. The chemical properties of PFA FEP PTFE are similar, but FEP can only be used below 200 degrees, and PTFE cannot be injection molded.
Application of 5. PFA board
Suitable for 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.
