Physical character: made by moulded or extruded with high quality polytetrafluoroethylene(PTFE) material. It is the best polymer material of chemical resistance in all knows plastic material. With excellent characteristics of corrosion resistance, weathering resistance, dielectric properties and lowest coefficient of fraction in all know solid materials in a wide range of practicable temperature from -180°C - +260°C and a wax-like surface to which anything hardly sticks. Ø2-9mm is made by paste extruded, Ø10-50mm is made by ram extruded, Ø50-300mm is made by moulded. It has the best electrical properties of all plastics. The electrical insulation used under various kinds of frequency, the seal liner of various kinds of corrosively medium, anti-sticking materials, lubrication material.
