PFA electrode is also called: PFA solid wire, soluble PTFE electrode, soluble PTFE solid wire
PFA electrodes are made by extruding soluble polytetrafluoroethylene (PFA) granular material. There are two kinds of round and flat.

Mainly used for welding of various plastics.
Welding skills: 1. before welding will be sticky surface with acetone or ethanol solution scrub clean, dry. 2. "V" type or "x" type mouth shall be adopted for welding reinforcement type
The workpiece welding surface and contact with the welding torch to 45. The corner is close to the weldment, keeping a distance of 5~10mm from the welding surface, the operating speed is 60~80 mm/min, and the welding air pressure is 0.098 ~ 0.294MPa;
With inert gas as medium heating to 420 ~ 480C, so that the PTFE welding surface melting, welding together at the same time, to be cooled after the weld mechanical processing to the required extent.
Common specifications: diameter 2.5/3.0/3.5MM flat: 12*2/14*2/18*2MM
PFA solid wire specifications, play the role of radial insulation. When the voltage exceeds 35,000 volts, the insulating material is applied to the conductor through the insulating tube or cable. There are two kinds of conductor structure of composite insulating sleeve
Cables and guide rods. The cable leading out through the transformer runs directly through the bushing and is easy to install. When the working current is greater than 600A, the guide rod structure is generally adopted, and the PFA solid wire in Yangzhong is difficult to install the cable screw.
texture. The capacitor bushing is composed of a capacitor core, a porcelain sleeve, metal accessories and a conductor.

Its creep resistance and compressive strength are higher than PTFE, tensile strength, PFA solid wire, elongation of up to 100-300%. Good dielectric properties and excellent radiation resistance. Flame retardant performance reached V0
Level. Suitable for the manufacture of corrosion-resistant parts, anti-friction parts, seals, insulation parts and equipment parts. High temperature wire, cable insulation, anti-corrosion equipment, sealing material, pump valve sleeve, chemical container. Insulating sleeve
It has better creep resistance and compressive strength than PTFE, and the tensile strength and elongation are as high as 100-300%; in addition, the environmentally friendly PFA insulating sleeve has good dielectric properties and excellent radiation resistance
Sex. PFA plastic is a small amount of perfluoropropyl perfluorovinyl ether and polytetrafluoroethylene copolymer. The melt viscosity increased and the solution viscosity decreased, but the properties did not change compared to PTFE. The resin can pass through
Direct processing over ordinary thermoplastic molding process.
Long-term use temperature -196-260 degrees, some chemical resistance, corrosion resistance to all chemicals, friction coefficient in plastic, and good electrical properties, its electrical insulation is not affected by temperature,
There is a "plastic king. Its chemical resistance is similar to polytetrafluoroethylene and better than vinylidene fluoride. Its creep resistance and compression strength are better than PTFE, PFA solid wire, high tensile strength,
Elongation can reach 100-300%. Good dielectric properties, excellent radiation resistance. Flame retardant up to V0 level.
