Polyvinyl Chloride

Polyvinyl chloride is a white, brittle solid available in powder form or granules. It is insoluble in all solvents but swells in the monomer and some chlorinated hydrocarbon solvents.

Polyvinyl Chloride is widely available in two broad categories: Flexible and Rigid. But there are more types  also available like CPVC, PVC-O and PVC-M. Plasticized or Flexible PVC (Density: 1.1-1.35 g/cm³): Flexible PVC is formed by the addition of compatible plasticizers to PVC which lower the crystallinity. These plasticizers act like lubricants resulting in a much clearer and flexible plastic. This type of PVC is sometimes called as PVC-P. It is used in plumbing, electrical cable insulation, flooring, signage, phonograph records, inflatable products. Unplasticized or Rigid PVC (Density: 1.3-1.45 g/cm³): Rigid PVC is a stiff and cost-effective plastic. It shows high resistance to impact, water, weather, chemicals and corrosive environments. This type of PVC is also known as UPVC, PVC-U or uPVC. Rigid PVC is used in construction for pipe, doors and windows. It is also used in making plastic bottles, packaging, and bank or membership cards and so many others .
