What does ABS stand for?
ABS is an acronym for Acrylonitrile Butadiene Styrene, a copolymer thermoplastic manufactured from the polymerization of Styrene and Acrylonitrile in the presence of Polybutadiene.
What is ABSâ€™s plastic number?
ABS does not have its own plastic number. Products made with ABS use recycling number 7, which represent â€œotherâ€ plastic types.
You may find ABS products marked with a recycling symbol and â€œABSâ€ written inside or beneath it.
What are properties of ABS plastic?
ABS properties are based on the proportions between acrylonitrile, styrene, and butadiene rubber. The typical composition is about 50% styrene with the balance divided between butadiene and acrylonitrile.
- ABS takes on the strength and rigidity of acrylonitrile and styrene polymers combined with the toughness of butadiene rubber.
- Acrylonitrile, when combined with Styrene makes ABS stronger than polystyrene (PS plastic).
- Styrene gives ABS a shiny, impervious surface.
- Butadiene rubber gives ABS high impact resistance and resilience even at low temperatures.
- If you want ABS to be tough with high impact resistance, you can increase the proportion of butadiene rubber.
- ABS is flammable with high smoke generation (black soot).
- ABS has limited weathering resistance (due to the butadiene rubber).
- ABS can be processed with ease, it can be machined, turned, drilled, milled, sawed, bored, die-cut, routed and sheared (using high speed carbide-tipped tools).
- ABS polymers are resistant to aqueous acids, alkalis, concentrated hydrochloric and phosphoric acids, alcohols and animal, vegetable and mineral oils.
- ABS is swollen by glacial acetic acid, carbon tetrachloride and aromatic hydrocarbons and is attacked by concentrated sulfuric and nitric acids.
- ABS is soluble in esters, ketones, and ethylene dichloride.
- ABS is relatively expensive (it takes 2KG of petroleum to produce 1KG of ABS plastic).
What are some products made from ABS plastic?
