The structure of ABS resin includes graft copolymers with elastomer as the main chain and graft copolymers with hard ABS resin as the main chain; or a mixture of rubber elastomer and hard ABS resin. In this way, different structures show different properties.
The elastomer shows the toughness of rubber, and the hard ABS resin shows rigidity. Several varieties such as high impact type, medium impact type, general impact type and special impact type are available. Specifically, as the content of rubber component B (generally 5% to 30%) increases, the elasticity and impact resistance of the resin will increase; but the tensile strength, fluidity, and weather resistance will decrease.
As the content of the resin component AS (generally 70%-95%) increases, the surface gloss, mechanical strength, weather resistance, heat resistance, corrosion resistance, electrical properties, and processing properties can be improved. The impact strength, etc. will be reduced. The ratio of A and B in the resin component is 30%~35%/80%~65% respectively.
