Welcome to inquire! Contact: Zhao Shuang. PVC material is polyvinyl chloride PVC plastic pipe price, it is a very versatile material PVC plastic pipe manufacturers, is frequently used in our lives. Such as PVC pipe, PVC flooring, PVC wallpaper and so on. Indian market demand for PVC is increasing year by year, the future of India will continue to rely on imported PVC supplement. 1, PVC classification of different production methods, PVC can be divided into: general-purpose PVC resin, a high degree of polymerization PVC resins, crosslinked PVC resin. General-purpose PVC resin is a vinyl chloride monomer after polymerization initiator formed; high degree of polymerization PVC resin refers to vinyl chloride monomer was added in the polymerization system, polymerization of the chain extender resin; a crosslinked PVC resin is was added in the polymerization system of vinyl chloride monomer and a polyene resin diene polymerization containing crosslinker. PVC by adding plasticizers, modifiers and fillers, so the proportion of PVC becomes very different, very different hard and soft PVC plastic pipe shaped, but also due to join some of the ingredients to make a lot of changes in the properties of PVC plastic , resulting in the identification method we used is not obvious, and even the phenomenon of change, can not make accurate judgments. For example: density, plasticized polyvinyl chloride (containing about 40% plasticizer) is 1.19 to 1.35; and rigid PVC products has increased to 1.38 to 1.50. If you are highly filled PVC products, density and sometimes more than two.
