Acrylonitrile butadiene styrene (ABS) is a terpolymer made from the polymerization of styrene and acrylonitrile in the presence of polybutadiene. Its ratio can be 15% to 35% acrylonitrile, 5% to 30% butadiene and 40% to 60% styrene.
ABS is one of the most widely used plastic raw materials due to its reasonable price and balanced mechanical and chemical properties. Other advantages of ABS include dimensional strength, high thermal resistance, and impact resistance.
Acrylonitrile butadiene styrene (ABS) is actually the result of a long chain of polybutadiene that is crosslinked with shorter chains of poly(styrene-acrylonitrile). ABS has the chemical formula (C8H8)x·(C4H6)y·(C3H3N)z and is a type of thermoplastic polymer. ABS is also produced as a compound, and the quality and poor quality of the compound have a great impact on the final product.
The datasheet of Acrylonitrile Butadiene Styrene (ABS) is as follows:

Applications of Acrylonitrile Butadiene Styrene (ABS)
Due to its features such as high impact resistance, thermal performance, etc., this material is one of the most used materials in the production of plastic, which is used in the production of household equipment such as refrigerators, vacuum cleaners, electronic devices such as keyboards, printers, mice, etc. Laptops and computers are used.
Among the applications of ABS in automobiles and transportation, we can mention instrument panels, column trim, dashboard components, door linings and handles, seat backs, seat belt parts, etc., which are among high-use materials.
Acrylonitrile butadiene styrene has favorable mechanical properties such as impact resistance, toughness and strength. By changing the ratio of ABS gear components, it can be produced with different grades. In general, acrylonitrile butadiene styrene has useful properties in the temperature range of 20 to 80 degrees Celsius.
Over time, after products made from ABS wear out, it can be converted into plastic flakes and reused to produce plastic products. Plastic flakes are actually crushed and small pieces of plastic products.
Production methods of acrylonitrile butadiene styrene (ABS)
Acrylonitrile butadiene styrene is produced in two ways:
In the first method, styrene-acrylonitrile copolymers are mixed with acrylonitrile-butadiene rubber. Typically, the rubber phase is broken and uniformly dispersed in small particles as the discontinuous phase in the continuous phase.
In the second method, which is used in most operations today, it provides greater versatility and the ability to custom design specific asset profiles. Acrylonitrile is grafted onto a butadiene or butadiene styrene copolymer backbone.
Features of Acrylonitrile Butadiene Styrene (ABS)
Impact Resistance
Among the features of ABS are its high impact resistance to impact and mechanical stresses.
Hardness and Strength
It has high hardness, which makes it suitable for producing products that must have high resistance to abrasion.
Chemical Resistance
It has high resistance to acids, bases and other chemicals and is resistant to corrosion.
Electrical Insulation
Due to the non-conductivity of ABS, it can be used to produce tools in contact with electricity.
Disadvantages of Acrylonitrile Butadiene Styrene (ABS)
Poor resistance to UV rays
For this reason, care must be taken when using this polymer to avoid direct sunlight.
Flammability
It burns easily unless its natural grades are used in the manufacture of products.
Not biodegradable
It is a plastic material that may be difficult to recycle and is challenging for the environment.
