PVC composition structure character as a slightly yellow translucent and shiny. Transparency better than polyethylene, polypropylene, polystyrene poor, with the additive, divided into soft and hard PVC, soft products soft and tough, feel sticky, hard ware harder than low-density polyethylene, but lower than polypropylene, will appear at the inflection bleaching. Common products: plates, pipes, shoe soles, toys, doors and windows, wire jacket, stationery, packaging boxes. PVC coated articles have a substrate is PVC leather cloth or paper spreads confused, then plasticizing above 100 ℃. PVC and additives may be first rolled into a thin film and the substrate and then laminated together. No artificial leather substrate is rolled directly into a certain thickness calender soft system slices, then press the pattern can be. Leather cover can be used to make cartons, bags, books, sofas and car seats, etc., as well as vinyl flooring, flooring materials used buildings. When PVC foam soft PVC mixing, adding an appropriate amount of foaming agent made of sheet molded foams foamed pvc pipe, it can be used for foam slippers, sandals, insoles, and shockproof cushion packaging materials. Extruder can also be used as the basis of rigid PVC foam sheet and low profile, and can replace the use of wood, it is a new type of building material. PVC transparent sheet PVC impact modifier was added and organotin stabilizers, by mixing, plasticizing, rolling and become transparent sheet. Use can be made of thin-walled thermoformed transparent containers or for vacuum packaging, is an excellent packaging materials and decoration materials. pvc crosslinking into radiation crosslinking and chemical crosslinking. 1. The radiation crosslinking. The use of high-energy rays, electron beams generally cobalt 60 radiation source generates radiation and electron acceleration produced, but mainly the latter. Coupled to help crosslinking auxiliary (two or more carbon-carbon double bond monocoque) crosslinking. But the operation is difficult, for equipment requirements. 2. Chemical cross-linking. Use triazol-dimercapto-crosslinked amine salts, amine salts triazol-dimercapto-FSH, amine crosslinking mechanism combined with the sulfhydryl attack carbon-chloro-polar bond implement substitution reaction product after crosslinking five pvc pipe UV resistant, solvent pvc pipe manufacturers, heat, impact toughness, etc., have comprehensive manner. And that device 1. solve the difficult problem of radiation cross-linked. 2. PVC toughening, weather, temperature, UV resistant and so performance has greatly improved. 3. mitigation of radiation crosslinked PVC or peroxide crosslinking degradation pvc pipe pressure to overcome the discoloration seriously flawed. To give the appearance of products with better performance. 4. simple process, suitable for molding, coating, rotational molding process and so on. pvc pipe pressure, sea Widex (online consultation), pvc pipe supplied by Widex Qingdao Rubber Material Co., Ltd.
