Acrylonitrile butadiene styrene, or ABS, is an amorphous thermoplastic made from the polymerization of styrene and acrylonitrile to polybutadiene, which will have different properties depending on the percentage of each monomer.
The presence of nitrile polar groups makes the ABS stronger than pure polystyrene. Styrene creates glossy, impermeable surfaces in plastic. Polybutadiene is a rubber material that causes toughness even at low temperatures. In general, it can be said that ABS compounds have useful properties at 20 to 80 ° C.
By changing the ratio of polybutadiene to other acrylic nitriles and styrene, the desired properties of this polymer can be altered. For example, changing the amount of this material can affect the strength and impact of the polymer.
ABS are resistant to aqueous acids, alkalis, phosphoric acids, alcohols, but are soluble in substances such as esters, ketones and ethylene dichloride.
These compounds can be flammable if exposed to sunlight and high temperatures.
ABS is easily machined. Common methods of machining include drilling, milling, sawing, cutting and ...
The low price, light weight and injectability of this polymer make it used in the manufacture of products such as drainage pipes, automotive components, medical supplies, kitchen appliances, computer keyboards, toys, LEGO bricks and more. .
In addition to all the benefits mentioned above, ABS also has its disadvantages which sometimes make it difficult to use this material. Some of these are: flame sensitivity, toxicity in the production process, high absorption of moisture, non-weathering resistance, etc.
This polymer breaks down to its constituents at temperatures above 400 ° C, including butadiene and acrylonitrile for human carcinogens.
