PVC fence material is a kind of plastic decorative material, which is the abbreviation of PVC. PVC resin is a thermoplastic polymer polymerized by Vinyl Chloride Monomer (VCM). PVC resin is a kind of PVC resin as the main raw material, adding an appropriate amount of anti-aging agent and modifier. And so on, by mixing, calendering, vacuum plastic process and so on. PVC is amorphous polymer with crystallinity of 5%--10% crystallite (melting point 175 degrees). The physical properties such as molecular weight, crystallinity and softening point of PVC change with polymerization conditions (temperature). PVC resin plastics were prepared by plasticizing and molding PVC resin as binder, mixed with stabilizer, plasticizer, filler, colorant and modifier.
