The polystyrene foaming
The foaming polystyrene - a product of suspension polymerization of styrene in the presence of a steam generator. The foaming suspension polystyrene is produced in the form of spherical particles which surface is processed by various substances preventing a congestion of electrostatic charges when transporting and improving technological effectiveness of polymer when processing.
Material possesses the closed cellular structure, for 95% consisting of gases which are used in the course of foaming. The important characteristic of material is the size of granules – fractions which defines its subsequent use.
On appearance of a granule of expanded polystyrene represent translucent parts of spherical shape of milky-white color. Material has low heat conductivity and, as a result, heat insulation.
The foaming EPS polystyrene is characterized by excellent sound insulation, high crash-worthiness, durability at stretching, compression and a bend, vibration resistance, light resistance, water - and a pylenepronitsayemost, is resistant to hydrolysis, fats, acids, solutions of alkalis and acids.
Polystyrene the foaming PSV is intended for production by method of thermoformation of warm and sound-proof materials in the form of blocks, decorative products of low density and drainage plates, food and technical packing and so forth.
