ABS Polymers

Kuniyamuthur, Coimbatore, Tamil Nadu

Acrylonitrilebutadienestyrene (ABS) polymers are composed of elastomer dispersed as a grafted particulate phase in a thermoplastic matrix of styrene and acrylonitrile copolymer (SAN). The presence of SAN grafted onto the elastomeric component, usually polybutadiene or a butadiene copolymer, compatabilizes the rubber with the SAN component. Property advantages provided by this graft terpolymer include excellent toughness, good dimensional stability, good processibility, and good chemical resistance. The system is structurally complex. This allows considerable versatility in the tailoring of properties to meet specific product requirements. Numerous grades of ABS are available, including alloys and specialty grades for high heat, flaming-retardant, or static dissipative product requirements. Good chemical resistance combined with the relatively low water absorptivity (

ABS POLYMERSHistoryAcrylonitrile-Butadiene-Styrene has been available since the 1940s and while its increased toughness over styrene made it suitable for many applications, its limitations led to the introduction of a rubber (butadiene) as a third monomer and hence was born the range of materials popularly referred to as ABS plastics. These became available in the 1950s and the variability of these copolymers and ease of processing has led to ABS becoming the most popular of the engineering polymers.

PC ABS: A compounded blend of Polycarbonate and ABS. The PC contributes impact and heat distortion resistance, while the ABS contributes process ability and chemical stress resistance, and cost reduction below PC. Properties of PC/ABS include the following:- Impact resistance between ABS and PC, (10-14 ft.-lb./in.)- Strength and stiffness between PC and ABS- Heat resistance superior to ABS, less than PC- Flame retardant system more stable in processing than ABS- Very good indoor UV light color stability- Low temperature impact and ductility- Superior process ability to PC
