ABS is a terpolymer and an amorphous resin. It is manufactured by combining three different compounds. The three that make ups of ABS are acrylonitrile, butadiene, and styrene. ABS occupies the unique position of being a bridge between the commodity and other higher performance engineering thermoplastics. Its performance is characterized by toughness and impact strength even at low temperatures, good stiffness and machinability.
ABS resins are terpolymers of acrylonitrile, butadiene and styrene. These medium-priced, amorphous thermoplastics are had, rigid and tough, even at low temperatures.
Various grades offer different levels of impact strength.
Most natural ABS resins are translucent to opaque, but they are also produced in transparent grades, and they can be pigmented to almost any color.
ABS plastics offer a good balance of tensile strength, impact and abrasion resistance, dimensional stability, surface hardness, rigidity, heat resistance,
low temperature properties, chemical resistance and electrical characteristics. ABS parts have enough spring to accommodate shallow, snap-fit assembly requirements.
Impact properties of ABS are exceptionally good at room temperature. General-purpose ABS grades may be adequate for some outdoor applications
(depending on design and performance requirements) but prolonged exposure to sunlight causes a color change and reduces surface gloss, impact strength, hardness and elastic modulus.
