PVC is the abbreviation of Polyvinyl Chloride, which is a kind of thermoplastic high polymer polymerized from Vinyl Chloride Monomer (VCM). PVC products are widely used engineering plastics. PVC products is produced with the use of PVC Resin as raw material and certain quantity of PVC Heat Stabilizer, PVC impact modifier, PVC lubricants and plasticizer by extrusion or injection technology. PVC is kind of amorphous polymer, which contains microcrystal with the crystallinity of 5%-10% (melting point 175oC).
Physical properties like molecular weight, crystallinity and melting point of PVC Resin vary as the change of polymerization condition (temperature). PVC plastic products are made up of PVC Resin as main ingredient, filler, PVC Stabilizer, Plasticizer, coloring agent as additives by plasticization-moulding process.
PVC products are characterized by light weight, heat preservation, moisture and sound resistance and easy installation. So they are widely used in our daily life, such as PVC water pipe, PVC door and window, PVC ceiling and cable & wire. PVC products have some typical properties, including flame retardancy, abrasion resistance, chemical and corrosion resistance and low leakage of gas and water vapor.
In short, PVC products are most cost-effective plastic products thanks to excellent physical and chemical properties.
