PFA Resin piping DS702

The melt adhesion increased, the viscosity of the solution decreased, but the properties of the solution did not change compared with PTFE. This resin can be directly processed into products by ordinary thermoplastic forming method. Suitable for making corrosion-resistant parts, abrasion-resistant parts, seals, insulating parts and medical device parts, high temperature wire, cable insulation layer, anticorrosive equipment, sealing material, pump valve bushing, and chemical containe.

The difference between "PTFE" and "PFA":

Appearance: PFA semitransparent, PTFE pure white opaque.

Temperature resistance: PFA -200 - 260 degrees, PTFE-200 - 250 degrees.

Raw material shape: PFA is granular and PTFE is powdery.

PTFE:

Polytetrafluoroethylene (Poly tetra fluoroethylene, written as PTFE), generally called "non stick coating" or "easy to clean material". This material has the characteristics of anti acid, alkali, anti organic solvent and almost insoluble in all solvents. At the same time, polytetrafluoroethylene is characterized by high temperature resistance, and its friction coefficient is very low, so it can be used as lubrication. In addition, it has also become an ideal coating for easy cleaning of water pipes.

Weathering resistance: low radiation resistance and low permeability: long exposure to the atmosphere, the surface and properties remain unchanged.

Nonflammability: the oxygen limiting index is below 90.

Acid and alkaline: insoluble in strong acid, strong base and organic solvent (including magic acid, or fluoro antimony sulfonic acid).

Antioxidant: corrosion resistant to strong oxidizing agents.

Acidity and alkalinity: neutral.

PFA:

PFA plastics are a small amount of copolymer of perfluoropropyl perfluorovinyl ether and polytetrafluoroethylene. The melting bond property is enhanced and the viscosity of the dissolved body drops. The properties are not changed compared with the polytetrafluoroethylene. The resin can be processed directly by ordinary thermoplastic molding. It is suitable for the manufacture of corrosion resistant parts, wear resistant parts, seals, insulation, and insulation. Medical device parts, high temperature wire, cable insulation, anti-corrosion equipment, sealing material, pump valve bushing, and chemical container.

For a small amount of perfluoropropyl perfluorovinyl ether and polytetrafluoroethylene copolymer. The melting bond property is enhanced and the viscosity of the dissolved body drops, but the properties are not changed compared with the polytetrafluoroethylene. This resin can be directly processed by ordinary thermoplastic molding.

Long term use of temperature -196--260 degree, excellent chemical corrosion resistance, corrosion resistance to all chemicals, the friction coefficient in the plastic is the lowest, and good electrical properties, its electrical insulation is not affected by temperature, the "plastic king" is known.

Its chemical resistance is similar to that of polytetrafluoroethylene, better than vinylidene fluoride.

Its creep resistance and compression strength are better than that of PTFE, high tensile strength, elongation of 100-300%., good dielectric resistance, excellent radiation resistance, flame retardancy up to V0 grade.

It is suitable for making corrosion resistant parts, grinding wear resistant parts, sealing parts, insulation parts and medical devices parts.

High temperature wire, cable insulation, anti-corrosion equipment, sealing material, pump valve bushing, and chemical container.
