ABS (thermopolymer material)
An abbreviation for terpolymers of acrylonitrile, butadine and styrene.
This material is a terpolymer of acrylonitrile, butadine and styrene.
Usual compositions are about half styrene with the balance divided between
butadiene and acrylonitrile. Considerable variation is, of course,
possible. Many blends with other materials such as polyvinylchloride,
polycarbonates and polysulfones have been developed and are the most common
class of plastics used in electroplated metal coatings for decorative
hardware.
ADVANTAGES:
- Good impact resistance with toughness and rigidity
- Metal coatings have excellent adhesion to ABS
- Formed by conventional thermoplastic methods
- A light-weight plastic
DISADVANTAGES AND LIMITATIONS:
- Poor solvent resistance
- Low dielectric strength
- Only low elongations available
- Low continuous service temperature
TYPICAL APPLICATIONS: Automotive hardware, appliance cases, pipe, plated
items.
Hope this helps,
John German
