[0002] Polytetrafluoroethylene is a high molecular polymer made by polymerizing tetrafluoroethylene as a monomer. It has excellent heat resistance and cold resistance. Composite pipes made of polytetrafluoroethylene can withstand greater pressure at higher temperatures.

[0003] When the existing polytetrafluoroethylene composite tube is hot formed, the polytetrafluoroethylene masterbatch needs to be melted first and then formed into a tube. However, during the forming process, it takes a long time to wait for the melted polytetrafluoroethylene to cool down, which in turn affects the production efficiency of the polytetrafluoroethylene composite tube. For this reason, we propose a polytetrafluoroethylene composite tube hot forming device. Utility Model Content
