ABS is composed of styrene, acrylonitrile and butadiene latex copolymer, its own heat resistance and solvent resistance are better than HIPS, and shiny. Because acrylonitrile nitrile polar strong, can enhance the PS molecular chain interaction, so the impact strength, tensile strength and surface hardness of plastic parts are better than HIPS.
In general, the higher the proportion of acrylonitrile, the better its heat resistance, rigidity and solvent resistance, but the poorer fluidity and yellowing of the plastic base color. The mechanical and dimensional stability during injection molding are very good Based on the above advantages, ABS resin becomes an excellent engineering plastic.
ABS resin is a milky white solid with a certain degree of toughness and a density of about 1.04 to 1.06 g / cm3. It is resistant to acid, alkali, salt corrosion is relatively strong, but also to some extent, resistant to organic solvents.
ABS resin can be normal in the environment of -25 ℃ ~ 60 ℃, and have good formability, the surface of processed products is smooth, easy to dye and electroplating. So it can be used for household appliances shell, toys and other daily necessities. Common LEGO blocks are ABS products.
