PFA Rod for making pfa gasket
PFA 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
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.%)
