INTRODUCING ABS

The acrylonitrile butadiene styrene (ABS) is a copolymer derived from styrene polymerized with acrylonitrile in the presence of polybutadiene. The proportions range from 15% to 35% of acrylonitrile, from 5% to 30% butadiene and from 40% to 60% of styrene. Its chemical formula is of the type (C8H8)· (C4H6)· (C3H3N)z.

CHARACTERISTICS AND APPLICATION FIELDS

The ABS, as most of the styrene polymers, may be injection molded, extruded, thermoformed, blow molded, welded, glued and engraved. In particular, the ABS is well adapted to the galvanisation.

The most important mechanical properties of ABS are resistance and impact strength. The stability under load is excellent with limited loads. Generally the ABS has useful characteristics in a temperature range from -20 ° C to 80 ° C. The ABS is resistant to aqueous acids, alkalis, hydrochloric acid, concentrated phosphoric acid, alcohols, vegetable and mineral oils, but is inflated by glacial acetic acid, carbon tetrachloride and aromatic hydrocarbons; also it is attacked by concentrated sulfuric and nitric acid. The ABS is soluble in esters, ketones, ethylene dichloride and acetone. Has good electrical properties, it is flammable at high temperatures and can be damaged by sunlight.

The lightness and workability make the ABS a material suitable for the manufacture of a wide range of products, such as pipes, musical instruments, coverings, dashboards for cars and housings, bumper bars for motor vehicles, medical instrumentation, enclosures for electrical and electronic assemblies, luggage, small kitchen appliances and toys, including LEGO bricks.
