ptfe tube PUSHING various performance indicators( ptfe tube ).
After ten year’s effort, Jiangyin Jiangnan Fluoroplastic Co.,Ltd had successfully produced larger size PTFE dispersion resin paste extruding tubes in 2010, which were never been manufactured since the establishing of the company. Single length of pipes sized atφ1 and φ150 are from 8 m ~ 15m. The normal production of paste extruding tubes of this type is significant, compared with previous producing process that many other factories make pipe formation by winding method and then process to produce waved hoses. Meanwhile products sized atφ80 and φ100 were formally started up to be produced at June 20th, 2006 at Jiangyin Jiangnan Fluoroplastic Co.,Ltd.
1.Flat and tidy surface
2. no defects
3.no crevices and separations.
4.Low minimum order quantity;
PTFE is the most chemical-resistant of all knownPlastics. It Has the best electrical properties of plastics.

ptfe tube can be used at the temperature of -180 to +260°C. It has the lowest frictional factor and the best anti-corrosive property among the known plastic materials. It is used as insulating covers for conductors and pipes for corrosive fluids, and applied in the automotive, electrical, industrial and appliance markets.
