Shanghai Daoqin Plastics Co., Ltd.

modified resin (ASA) is types acrylonitrile (acrylonitrile), styrene (Styrene), acrylic 橡胶(Acrylate)组 formed upper 世纪70 year made formed ternary polymer, belongs to impact resistant modified resin. ASA and ABS structure versus 似, its ABS as is engineering plastics tool has machine physical properties.

ASA is USA general purpose electrical (GE) lower general purpose plastics group (GE Plastics) types main/primary product, 并于2002 year 8 month 以Geloy 注册商标 will its as is Raw Materials toward China pvc color color type market.

ASA product specifications table/sheet:

ASA processing conditions:

A, drying: 90-95℃, 3 small 时, below/following 变数而变（a） wet degree （b） recycling material ratio/proportion （c）储存 conditions

B, injection shot machine sleeve/set setting temperature degree

D, pressure 50-70kg/cm², holding pressure 40-60kg/cm², back pressure 5-15kg/cm²

ASA advantages:

1, ASA tool has good machine physical properties

ASA and ABS structure versus 似, acrylonitrile and butadiene 橡胶组 formed, its ABS as is engineering plastics tool has machine physical properties.

2, ASA tool has very strong/high weather resistance

polymer/macromolecule polymer in has di 键, di easy by can amount strong/high degree relatively large cationic light in outer 线 打开, 由此造 formed polymer/macromolecule polymer resistant aging property can decline, 而ASA positive is use 不含不 saturated and di acrylic substitute/replace ABS in has saturated and di butadiene 橡胶, therefore, can UV resistant 照射引起 degradation, aging, color, meanwhile for large gas in oxidation processing process in high temperature separation understanding or color has strong/high 保障, 由此极 large improves material anti-aging and resistant property can. according to testing 结果, ASA anti-aging property can is ABS 10倍 above.

3, ASA tool has comparison good high temperature resistance property can

4, ASA is types anti-static material, can make surface less 积灰尘

ASA application areas

automotive field/area:ASA in long time rear, 也不会像经特殊处理 resistant aging ABS that formed color (due to or water formed surface many micro and gas 蚀). ASA typical applications is outer 视镜, dispersion hot device 格栅, 尾部档 sheet/plate, lamp covers and other day and 雨淋, strong/high and other poor conditions lower external parts. currently, more is 逐步延伸 to 摩托车面 sheet/plate, automotive, small type housing/shell, sheet/plate and other field/area.

园艺 field/area:ASA by especially suitable for 园艺灌溉 equipment and 草坪切割 machine outer housing/shell and other.

electronics electrical field/area: by excellent used for resistant use equipment outer housing/shell, 如:缝纫 machine, electrical machine, equipment, 卫星天线 and other full housing/shell 体.

construction field/area:ASA/PVC掺 mixed material used for 屋面护墙 sheet/plate and type material, this 方面, outer already has ultra- 10 year application 经历.

due to ASA surface quality good and color stability, already by used for high grade and products, cold hot water device and other, this table/sheet 明ASA also tool has for agent and agent corrosion resistant property.
