Acrylonitrile Butadiene Styrene is a white to off-white powder.The melting point is 58.54（±0.5）℃.It is soluble in acetone,MEK and DMK. CAS: 9003-56-9. It is a copolymer made by polymerizing styrene and acrylonitrile in the presence of polybutadiene.
ABS has good impact strength also at low temperatures. It acts directly on the monomer during polymerization. Molecular Weight: 633.91g/mol. The proportions can vary from 15 to 35% acrylonitrile, 5 to 30% butadiene and 40 to 60% styrene. The result is a long chain of polybutadiene criss-crossed with shorter chains of poly(styrene-co-acrylonitrile). The nitrile groups from neighboring chains, being polar, attract each other and bind the chains together, making ABS stronger than pure polystyrene. Acrylnitrile contributes with thermal and chemical resistence, and the rubberlike butadiene gives ductility and impact strength. Styrene gives the glossy surface and makes the material easily machinable and less expensive.
Acrylonitrile butadiene styrene materials can be processed by any of the standard thermoplastic processing methods. It can also be used to alter the rheology (deformation and flow) of polypropylene to make it more fluid and easier to process. Molecular Formula: C45H51N3X2. ABS is derived from acrylonitrile, butadiene, and styrene and carbon. Acrylonitrile is a synthetic monomer produced from propylene and ammonia; butadiene is a petroleum hydrocarbon obtained from the C4 fraction of steam cracking; styrene monomer is made by dehydrogenation of ethyl benzene — a hydrocarbon obtained in the reaction of ethylene and benzene. It has satisfactory stiffness and dimensional stability, glossy surface and is easy to machine.
