THERMOCOL

Thermocol contains an important thermoplastic compound, called polystyrene which is obtained by the polymerisation of styrene or phenylethene. The chemical properties of phenylethene are identical to polyethene.
THERMOCOL is mainly used as a covering box for expensive materials of glass etc . it is also used in craft making
.
Polyvinyl Chloride (PVC)

A major thermoplastic material with a very wide variety of applications, the essential materials for polyvinyl chloride are derived from oil and salt. The vinyl chloride monomer (VCM) is formed by combining ethylene (obtained from oil) with Chlorine (produced from the electrolysis of salt water.

Regular PVC (polyvinyl chloride) is a common, strong but lightweight plastic used in construction. It is made softer and more flexible by the addition of plasticizers.

PET

Polyethylene terephthalate (sometimes written poly(ethylene terephthalate)), commonly abbreviated PET, PETE, or the obsolete PETP or PET-P, is the most common thermoplastic polymer resin of the polyester family .

it is used in fibers for clothing, containers for liquids and foods, thermoforming for manufacturing,
