ABS is synthesized from three chemical monomers: acrylonitrile, butadiene and styrene. Each monomer has different properties: acrylonitrile has high strength, thermal stability and chemical stability; butadiene has toughness and impact resistance; styrene has easy processing, high finish and high strength. From a morphological point of view, ABS is a non-crystalline material. The polymerization of the three monomers produces a terpolymer with two phases, one is a continuous phase of styrene-acrylonitrile and the other is a dispersed phase of polybutadiene rubber. The properties of ABS mainly depend on the ratio of the three monomers and the molecular structure of the two phases. This allows great flexibility in product design and has resulted in hundreds of different qualities of ABS materials on the market. These different qualities of materials provide different properties, such as medium to high impact resistance, low to high finish and high temperature distortion characteristics. ABS materials have super easy processing, appearance characteristics, low creep and excellent dimensional stability as well as high impact strength.
