Description
PTFE extruded tubing is manufactured by high pressure PTFE dispense resin mixed with additive, it is extruded and sintered. According to different demands, the tubing could be opaque or translucent.
PTFE is well known for its chemical resistance, not aging, non stick, self-lubrication, insulation and wide working temperature range from -180°C to +260°C. Because of these excellent properties, PTFE has a wide application in fields of chemical, mechanical, electronics, medical and aviation, etc.
Application
Used as wire and cable jacket, inner lined pipes for corrosive fluids and used in hydrochloric acid heat exchanger, etc.
