ABS Material

ABS polymer is made by polymerizing styrene and acrylonitrile in the presence of butadiene, and the resulting polymer demonstrates superb impact-resistivity ranging from room temperature down to 40℃ below the freezing point; Acrylonitrile exhibits excellent weather resistance and heat tolerance, and butadiene bears the physical property of impact-resistance while styrene gives plastic a shiny surface and excellent molding ability. The typical proportion of the above in ABS polymer is 20:30:50, and the final properties of the polymer can be influenced by conditions under which the materials is processed, and these include the proportions of the three monomers, the polymerizing methods, and pellets size ... etc. For instance, when the amount of butadiene is increased the derived ABS polymer will exhibit amplified impact strength, but also at the cost of rigidity, melt flow index, toughness, and heat tolerance. ABS polymers were once categorized as engineering plastics, but as its productivity had seen enormous increase to the point which rivals its predecessor, PS polymers, it has become one of the top five general-purpose plastics by category since the year 2000.
