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. Ever 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 various
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 starex ABS
is 85℃ to 95℃. Starex 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.
