What material is ABS?

ABS (acrylonitrile-butadiene-styrene * * * polymer, ABS is acrylic acid? Butadiene? Styrene is a thermoplastic polymer material with high strength, good toughness and easy processing and molding. Its glass transition temperature is about105 c (221f). ABS is amorphous, so it has no real melting point.

ABS has two main industrial production methods:

1. Mix acrylonitrile-styrene * * * polymer (AS) with polybutadiene (B), or mix two kinds of latex and polymerize * * *;

2. Acrylonitrile and styrene monomers were added into polybutadiene latex for graft copolymerization.

nature

ABS resin is a milky white solid with certain toughness, and its density is about 1.04~ 1.06? G/cm? . It has strong corrosion resistance to acid, alkali and salt, and can also tolerate the dissolution of organic solvents to a certain extent.

ABS resin can work normally in the environment of -25℃~60℃ and has good moldability. The surface of the processed product is smooth and easy to dye and electroplate. Therefore, it can be used in household appliances, toys and other daily necessities. Common Lego bricks are ABS products.

ABS resin can be mixed with various resins, such as PC/ABS, ABS/PVC, PA/ABS, PBT/ABS, etc. And generate new performance and new application fields. For example, a transparent ABS resin can be manufactured by mixing ABS resin with PMMA.
