    PFA welding rod. Ptfe welded rod , PTFE welding rod , Teflon welding rod

    PFA welding rod is made from PFA resin and prepared by the technology of extrusion and molding. It can be machined into various sealing parts and electric components. It can be used at the temperature range of -200 through +260C degree. It is widely used for welding PTFE products, PFA products.

    PFA electrode material performance:
    1. for a small amount of perfluorinated propyl perfluorinated vinyl ether copolymer with ptfe.Molten enhanced bonding, melt viscosity decreased, and there were no changes in performance compared with ptfe.This kind of resin can be directly processed into products using common thermoplastic molding method.
    2. long-term use of PFA electrode temperature - 80-260 degrees, have excellent chemical corrosion resistance, for all chemical corrosion resistance, friction coefficient, the lowest in the plastic and good performance, the electric insulation is not affected by temperature, is regarded as "plastics king".Its resistance to chemicals and ptfe are similar, is better than partial fluorine ethylene.
    3. the creep resistance and compression strength is better than teflon, high tensile strength, elongation of up to 100-300%.Good dielectric properties, resistance to radiation performance.Flame retardancy.


    Application:

    1.Petrochemical and chemical processing

    2.Electrical applications

    3.Semi-Conductor Industry

    4.Food, Beverage and Pharmaceutical industries

    5.Laboratory applications

    Lining Bearing pads, seals, and electrical insulation Lining Bearing pads, seals, and electrical insulation, liner tube, insulator tubing.

    It is mainly used toweld kinds of pfa or PTFE products .


    Characteristic

    1. High and low temperature preservation

    2. -200~260°C high temperature intensity better than F4

    3. No-begriming ,and no-stagnant in tube

    4. Security and insulation

    5. Under 60HZ—60MHZ high and low temperature , permittivity is 2.1

    6. If firing, and will still insulate

    7. Voltaic are>165 seconds insulation

    8. Erode preservation

    9. Under high temperature, fluorin and alkali will reaction with PFA, no reaction with other acid.

    10. Low water absorption<0.01%

    11. No firing in air( oxygen index>95 vol.%)
