PTFE Customized Flexible Extruded Smooth Bore Tubing OEM Manufacturer
Ptfe Flexible Tubing Product Description：
1. Polytetrafluoroethylene was first discovered in the 1930s by Dr. Roy Plunkett, a scientist at DuPont, and was first used in the top-secret Manhattan Project during World War II.
2. In the late 1940s, DuPont commercialized polytetrafluoroethylene (PTFE) under the name of PTFE. Extrudable grades of PTFE were later commercialized.
3 .As the polymer of choice for many advanced applications, polytetrafluoroethylene has many unique properties. Polytetrafluoroethylene has the lowest coefficient of friction of all polymers and a very wide operating temperature range, so it can be applied to various products from advanced medical equipment to high-temperature industrial equipment. Due to its incomparable chemical inertness, PTFE has become the plastic of choice in the chemical and analytical science industries.
4 .Our PTFE plastic can be made into various sizes of PTFE pipes (and modified PTFE). Smooth or curved (spiral or parallel), metric, imperial and AWG sizes. PTFE pipes can be made into straight pipes and packaged in coils or spools, and the cutting length can be customized. The natural color of PTFE tubing is milky white until slightly transparent. Other colors and pads are also available (in stock).
