Unfilled PTFE tube is a high-performance engineering plastic valued for its outstanding chemical resistance, exceptionally low friction, and broad operating-temperature range. Its naturally non-stick surface, minimal moisture absorption and excellent electrical-insulation properties make it suitable for demanding industrial, laboratory and engineering applications.
Supplied as hollow tube stock, it reduces machining time and material waste when producing bushes, sleeves, bearings, seals, insulators and other annular components. Unfilled PTFE is easy to machine and provides reliable performance where conventional plastics may be affected by aggressive chemicals, heat or friction.
