Product
1. The Characteristics of 25kV PTFE Coated Railway Composite Insulator
Polytetrafluoroethylene (PTFE, Teflon) is made of 100% pure polytetrafluoroethylene (or polytetrafluoroethylene as the matrix filling or coating other special performance materials), which has excellent chemical stability: high and low temperature resistance, chemical corrosion resistance, high lubrication and non adhesion performance, electrical insulation performance, anti-aging performance, and extremely low friction coefficient. It has been widely used as a sealing material in various media environments in various industries.
Polytetrafluoroethylene insulator products have the advantages of good surface smoothness, excellent insulation performance, and high electrical breakdown strength. And it is resistant to chemical corrosion, has dielectric properties, weather resistance, non flammable and non sticky, low friction coefficient, and can withstand high temperatures (-180 ℃~260 ℃).
