Teflon PFA tube has excellent chemical stability, mechanical properties, electrical insulation, self-lubricating, non-sticky, non-flammable and aging resistance. Its outstanding feature is that the melt viscosity is much lower than that of PTFE, so it can be processed by ordinary thermoplastic forming methods. Its products have good high temperature stability, high temperature mechanical strength is about 2 times that of PTFE, PFA film is softer than PTFE, with good bending and cracking resistance.
1. PFA tube translucent granular material, injection molding, extrusion molding. The molding temperature is 350-400 degrees above 475 degrees.
2. The forming temperature of the PFA tube should not 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.
PFA tube high temperature wire, cable insulation, anti-corrosion equipment, sealing material, pump valve bushing and chemical container.
4. PFA tubes are suitable for the manufacture of corrosion-resistant parts, anti-friction parts, seals, insulation parts and medical devices.
5. The PFA tube corrodes due to the molten material. For long-term production, the mold needs to be chrome plated.
The PFA hose is a copolymer of perfluoropropyl perfluorovinyl ether and polytetrafluoroethylene. Compared with PTFE, its melt cohesion is enhanced and the solution viscosity is reduced, but the performance is unchanged. Such resins can be processed directly into products by conventional thermoplastic forming methods.
(2)PFA hose has been used for a long time in the temperature range of -80~260 ℃. Some hoses have chemical resistance, corrosion resistance to all chemicals, and good electrical properties. Their electrical insulation is not affected by temperature, so they are called "the king of plastics".
Its chemical resistance is similar to polytetrafluoroethylene and better than vinylidene fluoride.
(4) its creep resistance, compressive strength is better than PTFE, tensile strength is also higher than PTFE. Its elongation can reach 100-300%. It has good dielectric properties and excellent radiation resistance.
Non-toxic: The PFA hose is inert and can be implanted in the body.
