Polyvinyl Chloride (PVC or Vinyl) is an economical and versatile thermoplastic polymer widely used in building and construction industry to produce door and window profiles, pipes (drinking and wastewater), wire and cable insulation, medical devices etc. It is the world’s third largest thermoplastic material by volume after polyethylene and polypropylene.
Key Properties of PVC Polymer
- Electrical Properties: PVC is a good insulation material, thanks to its good dielectric strength
- Durability: PVC is resistant to weathering, chemical rotting, corrosion, shock and abrasion. It is therefore the preferred choice for many long-life and outdoor products
- Flame Retardancy: Because of its high chlorine content, PVC products are self- extinguishing. Its oxidation index is ≥45. Antimony trioxide has been used extensively, usually in combination with phosphate ester plasticizers, giving excellent fire performance and mechanical properties.
- Cost/Performance Ratio: PVC has good physical as well as mechanical properties and hence provides excellent cost-performance advantages. It has long life span and need low maintenance
- Mechanical Properties: PVC is abrasion-resistant, lightweight and tough
- Chemical Resistance: PVC is resistant to all inorganic chemicals. It has very good resistance against diluted acids, diluted alkalis and aliphatic hydrocarbons. Attacked by ketones; some grades swollen or attacked by chlorinated and aromatic hydrocarbons, esters, some aromatic ethers and amines, and nitro- compounds
