ABS is a product of copolymerization of acrylonitrile, butadiene and styrene, i.e. a modification of high-impact polystyrene. ABS plastic sheets are laminated by single- or multilayer extrusion of the highest strength.

Polypropylene sheet is obtained by extrusion of polypropylene. It shows practically no hygroscopic properties, has perfect chemical resistance to most aggressive environments. It is used in concentrated and weak organic and inorganic acids. Ideal non-conductor.

Polystyrene – plastic, in outward appearance identical to transparent Perspex. The most popular are colourless and tinted sheets.

LPPE is a kind of polymers belonging to the class of polyolefins. Polyolefins make up over 60% of all 150 mln tons of polymers produced in the world.

JSC "Gomel Plant “Impuls (Impulse)" offers its products: sheets and strips polyethylene, polypropylene, polystyrene (TU BY 400047620.001 - 2008).

JSC "Gomel Plant “Impuls" makes reception and processing of waste of1-3 hazard class (polyethylene, polypropylene, polystyrene, etc.)

High-impact polystyrene

Polystyrene – plastic, in outward appearance identical to transparent Perspex. The most popular are colourless and tinted sheets.

 

In the unmodified state polystyrene is a fragile material. High-impact polystyrene is obtained from initial raw material by introducing special additives to it allowing to increase impact resistance and plasticity (according to international classification HIPS). Polystyrene sheets are obtained by extrusion method.

 

High-impact polystyrene is obtained with the help of extrusion apparatus. Modified additives are introduced into general purpose polystyrene. They increase its hardness and viscosity. Transparence is changing but the material itself becomes much stronger. This plastic is cold resistant that is why the scope of its application is so diverse – from construction to toy production. The most asked-for are the sheets of high-impact polystyrene 3-4 mm thick with one-sided embossing which are called “shagreen”. They are of several kinds and textures.

 

Polystyrene is easy in processing. Easy to glue together and paint. It has a good cohesion with vinyl films and is ease at molding / forming.

 

Multicoloured palette of light and strong polystyrene sheets with a perfect quality of the surface resistant to the environmental activity and ease in processing gives inexhaustible abilities to transformation and attracts attention of designers.

 

HIGH-IMPACT POLYSTYRENE HAS GOT:

  • Increased impact resistance;
  • break resistance;
  • flexibility;
  • cold resistance up to - 40°С;
  • moisture resistance;
  • perfect moldability;
  • easiness in processing.

The surface may have different types of embossing.

 

APPLICATION AREA

External ads, signboards, design of trading halls, shops, cafes and restaurants, concert halls, etc. Perfect molding of polystyrene allows tocreate exclusive volumetric items for advertising and design. It is used in food industry and in manufacturing of household appliances (internal parts for refrigerators). Molding of different raised elements, furniture for bathrooms, bodies for various devices. Polestyrene “shagreen” is used for aquariums (the most “trendy” material for covers and pedestals). Polystyrene is widely used for commercial and exhibition equipment. In printing – for producing and promoting of goods, business cards. In civil engineering – polyrstyrene sheets are used as facing materials to decorate trading halls, shops, office interiors, etc.
