ABS is an amorphous polymer with good Impact Strength and excellent appearance. It is easy to process and is widely used for computer housings, small appliances, automotive interior trim, and medical components. It is available in flame retardant grades, and medical grades.
ABS has poor chemical resistance.
These alloys offer improved strengths over ABS at a lower cost than Polycarbonate. Exceptional low temperature Impact Strength. Flame retardant grades are available. Due to the world shortage of polycarbonate production capacity, lead times for these materials are long, and availability is limited. Acetal polymers are semi-crystalline.
