Process of Polytetrafluoroethylene Tubing

- Dec 26, 2019-

The forming process of the PTFE pipe has a pressing method, an extrusion method, a hydraulic method, a welding method, a winding method, and the like, and the pressing method is mainly used. Generally, a dispersed PTFE resin having a particle diameter of 500 μm and an apparent density of 0.45 g/ml to 0.55 g/ml is used. The small diameter tube is made of a resin with a relatively large compression, and the large and medium diameter tube is made of a resin with a relatively small compression. The propellant is usually selected from solvent oils No. 200 and No. 260. The PTFE pipe is subjected to secondary processing to obtain a PTFE heat shrinkable pipe, a PTFE spiral pipe, a PTFE steel wire reinforced hydraulic pipe, and the like.
