PVC is substituted with a chlorine atom using a polymer material of polyethylene, one hydrogen atom. Structure of this material is as follows: [-CH2 -CHCl-] n. Carbon atoms arranged in a zigzag PVC pipe line, are σ-bonded to all atoms. All carbon atoms are sp3 hybridized low green plastic tubing formulation design, PVC plastic pipe certain principles for formulation. PVC macromolecular structure instability exists in the structure of the head structure, a branched chain, a double bond, allyl chloride, tert-chloride and the like, so that heat deformation resistance and poor aging drawbacks. After pretending to be cross-linked PVC pipe line products that can eliminate the disadvantages of the class. PVC material is polyvinyl chloride, which is a very versatile material, often used in our lives. For example, the price of PVC pipe PVC pipe line, PVC floor PVC plastic pipe line, 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.
