Currently municipal pipe market in China, is steadily developing plastic pipe, PE pipes, PP-R pipe, UPVC pipes have a place pvc insulated casing, where the strong momentum of development of the most remarkable PE pipe. Extensive field use PE pipe. Water and gas pipes which are the two largest application market. PE resin, is formed by the polymerization of vinyl monomers, because due to the pressure during the polymerization, the polymerization temperature and other reaction conditions are different, different densities of the resin can be obtained, and therefore there are high-density polyethylene, medium density polyethylene and low-density polyethylene ethylene points. In the processing of different types of PE pipe, depending on the application conditions, the choice of different grades of resin insulating sleeve, while the extruder and die requirements are different. PC tube (Polycarbonate Tube) is a transliteration of polycarbonate plastic tube, polycarbonate tube in general. Ptfe insulated casing with high transparency, light transmission rate of 92% is characterized by pfa insulating sleeve, the "plastic crystal" reputation. And have excellent weathering resistance, especially applied to outdoor, ranking the highest in other plastics, and both a good surface hardness and gloss, processing plasticity, etc., can be made into a variety of shapes and products needed. pfa insulating sleeve insulating sleeve _ _ the crown insulating sleeve (view) provided by the Dongguan City, the crown plastic products Limited. Dongguan City, the crown Plastic Products Co., Ltd. (www.gddgyg.com) strong, credible, in Dongguan, Guangdong wire, pipe, plate manufacturing equipment industry has accumulated a large number of loyal customers.
