ABS (Acrylonitrile-butadiene-styrene * * * polymer, ABS is acrylic? Butadiene? Styrene is a thermoplastic polymer material with high strength, good toughness and easy processing and molding, and 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, acrylonitrile-styrene * * * polymer (AS) and polybutadiene (b) are mixed, or the two kinds of latex are mixed and then polymerized;

2. Adding acrylonitrile and styrene monomer into polybutadiene latex for graft copolymerization.

Extended data

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 behave normally in the environment of -25℃~60℃, and has good formability. The processed products have smooth surface and are easy to dye and electroplate. Therefore, it can be used in household appliances, toys and other daily necessities. The common Lego bricks are ABS products.

ABS resin can be mixed with a variety of resins, such as PC/ABS, ABS/PVC, PA/ABS, PBT／ABS, etc., resulting in new properties and new application fields. For example, transparent ABS resin can be made by mixing ABS resin with PMMA.
