Industrial-grade Pvc Resin
Product introduction
Polyvinyl chloride (PVC) is a polymer compound formed by polymerization of vinyl chloride monomer (VCM). Its structural unit (-CH2-CHCl-) N, n is the degree of polymerization, usually in 590-1500.In the process of repolymerization, due to the influence of various factors such as polymerization process, reaction conditions, reactant composition and additives, 8 different types of PVC resins can be produced, so the properties of various resins are different.According to the amount of PVC resin containing vinyl chloride can be divided into: industrial grade, food grade, health grade three.Appearance of PVC resin: white powder or white particulate, its average density: 1.40g/cm2.GaugeSg-3, its degree of polymerization is 135-127;Sg-5, its degree of polymerization is 118-107;Sg-7, its degree of polymerization is 95-87;Sg-8, its degree of polymerization is 86-73;ApplicationPVC resin is widely used in the production and processing of PVC hard products, soft products, coatings and adhesives.(1)PVC general soft products can be squeezed into hose, cable, wire and so on by extruder;Using injection molding machine with a variety of molds, can be made into plastic sandals, soles, slippers, toys, auto parts, etc.(2)PVC film PVC and additives mixed, plasticized, the use of three or four roller calendering mechanism into a specified thickness of transparent or colored film, with this method of processing film, become calendered film.Can also be cut, thermal processing packaging bags, raincoats, tablecloths, curtains, inflatable toys, etc.Wide transparent film can be used for greenhouse, plastic greenhouse and mulch.The bidirectional stretching of the film, the characteristics of heat shrinkage, can be used for shrink packaging.(3)PVC coated products have a substrate of artificial leather is the PVC muddle applied to cloth or paper, and then plasticized at more than 100 degrees Celsius.Can also be PVC and auxiliary calendering film, and then pressed into the substrate.The leatherette without a substrate is directly calendered into a certain thickness of soft sheet, and then pressed on the pattern.Artificial leather can be used to make the cover of suitcases, bags, books, sofas and car cushions, and floor leather, used as building paving materials.4)PVC foam products soft PVC mixing, adding the right amount of foaming agent to do sheet material, after foaming molding for foam plastic, can be used as foam slippers, sandals, insoles, and shockproof cushioning packaging materials.Can also be extruded into low foaming hard PVC sheet and profile, can replace wood trial, is a new type of building materials.(5)PVC transparent sheet PVC add impact modifier and organic tin stabilizer, after mixing, plasticizing, calendering and become transparent sheet.The use of hot molding can be made into thin-walled transparent containers or used for vacuum plastic packaging, is an excellent packaging materials and decorative materials, such as moon cake packaging box.(6)PVC hard board and sheet PVC add stabilizer, lubricant and filler, after mixing, with the extruder can be extruded all kinds of caliber of hard pipe, special-shaped pipe, corrugated pipe, used as water pipe, water pipe, wire casing or stair handrail.The calendered sheet overlaps hot pressing, can be made into a variety of thickness of the hard plate.The sheets can be cut into the desired shape and then welded with hot air using PVC electrodes to form a variety of chemical-resistant storage tanks, air channels and containers.
