Acrylonitrile Butadiene Styrene (ABS)
The ABS three monomer system can be tailored to yield a good balance of properties. Basically, styrene contributes ease of processing characteristics, acrylonitrile imparts chemical resistance and increased surface hardness, and the butadiene contributes impact strength and overall toughness. ABS is considered the best of the styrenic family. It is hard, tough and rigid. (Source: RTP Company)

Advantages of ABS Plastic
Excellent impact resistance. It can have good appearance for cosmetic parts. Strength is moderate. Good resistance to acids and bases.
- Flame Retardant
- Heat Resistance, High
- Impact Resistance, Good

- Processability, Good
- RoHS Compliant
- General Purpose
- Flow, Good
- Flow, High
Disadvantages of ABS Plastic
It is sensitive to thick sections in your part which may cause voids, bubbles or sink. Attacked by hydrocarbons and organic solvents. Heat resistance is low. Price is relatively high.
- Limited weathering resistance
- Moderate heat, moisture and chemical resistance
- Relatively high cost
- Flammable with high smoke generation
Background of ABS Plastic
Acrylonitrile Butadiene Styrene was first discovered during World War II when its basis, SBR, was used for alternatives to rubber. Commercially ABS polymers first became available in the early 1950s in an attempt to obtain the best properties of both polystyrene and styrene acrylonitrile.
