The AS material mentioned in the plastic product is AS resin, which is a transparent solid with yellow to amber needle color. AS material is known as acrylonitrile-styrene copolymer. A polymer compound obtained by copolymerizing acrylonitrile and styrene. It has thermoplasticity. Not easy to change color. Not affected by dilute acid, dilute alkali, dilute alcohol and gasoline. However, it is soluble in acetone, ethyl acetate, dichloroethylene or the like. Can be used as engineering plastics.
The AS material is prepared by acrylonitrile and styrene by bulk, suspension or emulsion methods. Transparent or translucent water white particles. The relative density is 1.06-1.08. The refractive index is 1.57. The equilibrium water absorption is 0.66%. The heat distortion temperature is 82-105 °C. High gloss, high transparency, high impact, good heat resistance and mechanical properties. It has high rigidity, high chemical stability, water resistance, oil resistance, acid resistance, alkali resistance and alcohol resistance. Soluble in ketone solvents and certain aromatics, chlorinated hydrocarbons. Medium weather resistance and high brittleness.
AS material is mainly used for electrical (socket, housing, etc.), daily goods (kitchen equipment, refrigerator, TV base, cassette, etc.), automotive industry (headlights, reflective, instrument panel, etc.), household goods (Tableware, food knives, etc.), cosmetic packaging, etc. Widely used in the production of oil-resistant, heat-resistant, chemical-resistant industrial products, as well as instrument panels, instrument panels, enclosures, battery boxes, junction boxes, a variety of switches and regulations.
