ABS (Acrylonitrile-Butadiene-Styrene)
Specifications
TECHNICAL DESCRIPTION
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.

GENERAL PROPERTIES
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).
TYPICAL APPLICATIONS
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
