Polystyrene

Polystyrene is one of the oldest known vinyl polymers. Transparency is preferred because of its good handling, fluidity, food compatibility, and many other features.

Polystyrene thermoplastics find significant applications in the manufacture of materials with high dimensional stability, good electrical properties, easy processing and aesthetic appearance, particularly where high impact strength is required.

It is widely used as insulating material, in thin walled cups, in cooling towers, in plastic parts of pipe foam, rubber, various tools, automobile parts, panels and electronic appliances. It is often used in disposable cups.
