Thermoplastics

A plastic part fabricated from ABS

ABS (Acrylonitrile-Butadiene-Styrene)

  • Excellent impact, chemical and
    abrasion resistance
  • Superior stiffness and strength
  • Easily machined and thermoformed
  • Easy to paint and glue
  • Good dimensional stability
  • Excellent electrical properties

Characteristics

ABS is a low-cost engineering plastic that is easily machined, fabricated and thermoformed. It has excellent chemical, stress and creep resistance. ABS offers a good balance of impact, heat, chemical and abrasion resistance, dimensional stability, tensile strength, surface hardness, rigidity and electrical characteristics. ABS remains hard, rigid and tough even at low temperatures. It is available in fire-retardant, heat-resistant and platable grades. Impact strength varies by grade.

Most natural ABS resins are translucent to opaque, but they can be produced in transparent grades and can be pigmented to almost any color. General purpose grades may work for some outdoor appications, but prolonged exposure to sunlight causes color changes and reduces surface gloss, hardness, impact strength and elastic modulus.

Applications

  • Plumbing parts
  • Housings and covers
  • Automotive instrument panels
  • Vacuum-formed parts
  • Prototypes
  • Food processing components
  • Bumpers
