Isostatic Pressing Bags of PTFE

Isostatic Pressing Bags of PTFE

Main applications of polytetrafluoroethylene (PTFE):

PTFE has a high melting point, high melt viscosity, and is very sensitive to shear in the amorphous state, and is prone to melt fracture. Therefore, conventional thermoplastic molding processes such as melt extrusion and injection molding cannot be used, and only similar powders can be used. Metallurgical methods for sintering.

The manufacture of filled PTFE is the same as the molding of PTFE. It can be processed by preforming, free sintering, or by plunger extrusion. The above processing technology is generally suitable for products with a certain wall thickness, and is not suitable for the processing of PTFE films. In recent years, a lot of research has been carried out in China. The more mature processing technologies include calendering for dispersed PTFE resins; metal turning using the characteristics of low hardness and good toughness of PTFE sintered products; in addition, there is a conventional extrusion method and In the extrusion processing of the synthesis method of the calendering method, the resin is not melted and plasticized, and the raw material is directly processed.

In addition to the primary processing technology introduced above, PTFE processing also has some newly developed secondary processing technologies worthy of attention, such as PTFE vacuum forming technology, thermocompression molding and thermal blow molding technology, and isobaric molding processing technology. PTFE is the first choice material for corrosion-resistant linings of corrosion-resistant pipes, pipe fittings, bellows, pump bodies, valves, kettles, tanks, towers and various standard equipment; as a sealing material, it is widely used in machinery, petrochemical, transportation, textile and construction industries Wide range; PTFE can also be used as valves, bearings, piston rings, guide rails and other parts that require corrosion resistance and low friction; according to PTFE film treatment, it has selective air permeability and can be used as a separation material to selectively permeate gas or liquid, especially for filtration Corrosive liquid; Due to the excellent biocompatibility of polytetrafluoroethylene, many people have conducted in-depth research on it as a biological material in recent years. In recent years, PTFE membranes have been developed at home and abroad as artificial organs, such as artificial blood vessels, Heart valves, etc., for example, have achieved good clinical results when they are used as artificial blood vessels and prosthetic scaffold materials in rhinoplasty.
