PVC is very hard, very poor solubility, only a small number of solvent dissolved in cyclohexanone, dichloroethane and tetrahydrofuran and the like, organic and inorganic acids, alkalis, salts are stable, chemical stability with temperature rise reduced. PVC dissolved in acetone - carbon disulfide or acetone - benzene solvents for dry spinning or wet spinning fibers from, say polyvinyl chloride, with flame retardant, acid, anti-microbial, wear-resistant, environmentally friendly features and has good heat retention and elasticity. Polyvinyl chloride is a chlorine atom using a polymer material such as polyethylene in a hydrogen atom. The structure of this material are as follows: [-CH2 -CHCl-] n. Zigzag arrangement of carbon atoms, are σ-bonded to all atoms. All the carbon atoms are sp3 hybrid green and low consumption of plastic pipe formulation design, PVC plastic pipe to certain principles formula design. PVC macromolecular structure exist in the head structure unstable structure, branched chain, a double bond, allyl chloride, tert-chloride and the like, so that the thermal deformation resistance and poor aging drawbacks. After pretending to be cross-linked pvc profiles, you can eliminate this class disadvantage. PVC, the abbreviation PVC (Polyvinyl chloride polymer = PVC molecular structure) pvc profile production, is a thermoplastic resin formed by the polymerization of vinyl chloride in the role of initiator. Vinyl chloride homopolymer. Vinyl chloride homopolymers and copolymers of vinyl chloride resin system call. PVC is amorphous white powder, a small degree of branching. Industrial production of PVC molecular weight generally in the range of 50,000 to 120,000, with a large polydispersity, molecular weight increases with decreasing polymerization temperature; no fixed melting point, 80 ~ 85 ℃ begins to soften, 130 ℃ into a viscoelastic state , 160 ~ 180 ℃ began to change for the viscous flow state; have good mechanical properties, tensile strength of about 60MPa, the impact strength of 5 ~ 10kJ / m2; has excellent dielectric properties. But for light and heat stability is poor, at above 100 ℃ or after prolonged exposure to sunlight, it will break down and produce hydrogen chloride pvc profiles market and further autocatalytic decomposition pvc profiles manufacturers, causing discoloration, physical and mechanical properties also decreased rapidly In the practical application of the stabilizer must be added in order to improve the thermal and light stability.
