ABS Plastic Material Properties

Acrylonitrile Butadine Styrene

ABS polymers are amorphous polymers readily synthesised by adding styrene and acrylonitrile to a polybutadiene latex. In the resulting polymer, some styrene acrylonitrile (SAN) is grafted on to the polybutadiene backbone chain while the remainder of the SAN forms a continuous matrix. It is the SAN grafted onto the polymer chains that makes the two phases compatible. This essentially gives ABS its strength and toughness. A wide range of ABS materials can be formulated from different combinations of the above three components.

ABS Generic

Polymer Type - Thermoplastic


ABS (Acrylonitrile-Butadiene-Styrene) is a copolymer composed of two copolymers and is one of the most common polymer materials. Styrene and Acrylonitrile form a linear copolymer (SAN) that serves as a matrix. Butadiene and Styrene also form a linear copolymer (BS rubber) which acts as the filler material. The combination of the two copolymers gives ABS an excellent combination of strength, rigidity, and toughness.


ABS has good chemical and stress-cracking resistance to inorganic salt solutions, alkalies, mineral acids (except strong oxidizing acids), and some mineral, vegetable, and animal oils. ABS is easily machined to close tolerances, is tough, dimensionally stable, and may also be thermoformed. Petroleum-based oils, solvents, and paints SHOULD NOT BE USED, as they will cause the material to craze. ABS is also one of the few non-metallic materials which can be readily electroplated (after an electroless plating surface has been applied using a selective etching process).


ABS is an economical, general purpose material used in a wide variety of applications, including: • aircraft interior trim   
• cassette holders  
• business machine housings  
• tote bins and trays  
• luggage  
• model building  
• water purification equipment  
• automotive parts  
• laboratory equipment  
• household fixtures  


Hard for a thermoplastic. Reasonably tough (maintains impact resistance to low temperatures). Easily processed (may be electroplated). Easily bonded. Good gloss surface finish.


Poor solvent and fatigue resistance. Poor UV resistance unless protected. Maximum continuous use temperature approx. 70°C ( 160°F ). Poor bearing properties (high friction and wear). High smoke evolution.
