ACRYLONITRLE BUTADIENE STYRENE (ABS)

ABS is a copolymerization of styrene, acrylonitrile, and butadiene latex. Its heat and solvent resistance properties are better than HIPS and it has gloss characteristics. Because acrylonitrile has stronger nitrile polarity, it can enhance the interaction of the PS in the molecular chain. Therefore, its impact strength, tensile strength, and plastic surface hardness are better compared to those of HIPS. Generally, the higher the content proportion of acrylonitrile, the better the heat resistance, rigidity,and solvent resistance properties; but the fluidity is worse and the plastic contains a yellow color. During injection mode, it has very good mechanical property and dimensional stability. Based on these advantages, the ABS resin has become an excellent engineering plastic.
