Polystyrene

Pure polystyrene is a colourless, hard and breakable thermoplastic, which is a material formed by melting. Isi s characterized by limited elasticity and high rigidity.

When mixed with admixtures, it constitutes a basis to many plastics. Products manufactured from this material are marked with PS letters.

Polystyrene, as a plastic, may have a colourless, slightly transparent or dyed to bright colours form. In comparison to polyethylene and polypropylene, it has lower temperature of softening and lower viscosity. This qualities guarantee easier production of small object with complex shapes with the use of this material.

This material is used for the production of: toothbrushes, artificial jewellery, CD boxes, elements of toys, mugs, various packaging (with exception of food packaging – PS has too low chemical resistance).

However, the most popular use of polystyrene is the production of its foamed form, popularly called styrofoam. It is broadly used for the production of building insulating boards, as well as various types of packaging.
