Description
PTFE extruded rod is manufactured by high pressure PTFE dispense resin mixed with additive, it is Plug extruded and sintered. According to different demands, the rod 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
Electrical Insulation, seal, Antisticking materials.
