ABS


Overview

ABS resin is widely used in various electrical and electronic components, automotive parts, toys, cameras and pipes as it has diversity in both its manufacturing methods and material characteristics. It features high impact and flexural strength, excellent mechanical properties, chemical resistance, mold ability, dimensional stability and paint ability. ABS resin performs in a variety of ways based on the polymerization process type chosen and the controlled interaction between base material and various additives. Since the first use of ABS resin on manufacturing pipes, the material has been developed to provide better melt flow characteristics and greater flexural strength. We now produce ABS resin that satisfies requirements regarding thermal stability, flame retardant and antistatic characteristics.

Features
The apparent properties of ABS resin are dependent on the composition of the monomers.
1) The excellent material property balances of mechanical properties, thermal properties, chemical resistance and gloss
2) The excellent melt flow characteristics, dimensional stability, appearance and secondary processability as in plating, painting and hot stamping
3) A wide range of products that provide versatility regarding material production that meets specific application requirements.

Classifications
1) Mechanical
The stress-strain curve for ABS reveals the material has outstanding elongation and impact strength characteristics compared with GPPS and SAN. These are the unique properties of ABS resin drived from the careful control of rubber particle size, content and morphology, as well as the molecular weight of matrix SAN.

2) Thermal
The heat distortion temperature range of ABS is 85℃ to 95℃. ABS shows relatively stable mechanical properties depending on temperature variations during the molding process. But the impact strength decreases abruptly at temperatures higher than 260℃ because decomposition may take place.
