Cheap price Pa66 Gf15 - High flow ABS-GF, FR high heat resistance for OA application – Siko

ABS is a terpolymer made by polymerizing styrene and acrylonitrile in the presence of polybutadiene. 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 crises-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. The acrylonitrile also contributes chemical resistance, fatigue resistance, hardness, and rigidity, while increasing the heat deflection temperature. The styrene gives the plastic a shiny, impervious surface, as well as hardness, rigidity, and improved processing ease. The polybutadiene, a rubbery substance, provides toughness and ductility at low temperatures, at the cost of heat resistance and rigidity. For the majority of applications, ABS can be used between −20 and 80 °C (−4 and 176 °F), as its mechanical properties vary with temperature. The properties are created by rubber toughening, where fine particles of elastomer are distributed throughout the rigid matrix.

ABS Features

Low water absorption. ABS combines well with other materials and is easy to surface print and coat.

ABS has excellent mechanical properties and its impact strength is excellent, so it can be used at very low temperatures:

ABS has excellent wear resistance, good dimensional stability and oil resistance.

The heat distortion temperature of ABS is 93~118 °C, and the product can be improved by about 10 °C after annealing. ABS can still exhibit a little toughness at -40 ° C and can be used in the temperature range of -40 to 100 ° C.

ABS has good electrical insulation and is hardly affected by temperature, humidity and frequency.

ABS is not affected by water, inorganic salts, alkalis and various acids.
