Shanghai Daoqin Plastics Co., Ltd.

AES copolymer and ABS resin tool has versus structure, is for ABS weather resistance development types engineering plastics. AES resin most USA Copolymer-Rubber company production, currently its industrial production more is using/adopting solvent liquid method, solvent liquid method solvent agent use amount large, separation pure process complex, mono 体, solvent agent amount large, high solid content AES resin solvent liquid method production core technology still in outer several large type enterprise in, inner enterprise method production. therefore, high solid content AES resin production process tool has separation important 意义.

AES resin made methods

AES resin made methods has combined formed method and blending method 2 types, combined formed method is 按预先 setting AN( acrylonitrile )/EPDM/St( styrene )配 material ratio , use solvent liquid polymerization, emulsion polymerization or polymerization combined formed, to material is types 以EPDM is 主链! 以SAN(St-2AN copolymer ) is new type grafting copolymer EPDM2-g-2SAN. blending method is utilizing increase technology will EPDM and SAN in melt lower mixed combined made 备, although industrial methods has solvent liquid polymerization method ,但 in inner outer research 者们坚持不懈 努 force lower, other made methods has relatively large 进展.

AES resin property can

AES resin tool has weather resistance, therefore make it long time in oxygen, outer outer 线, light 照, wet, and other this conditions lower, it coating is can maintain it material property stability. therefore AES resin especially combined in outer 直接进行 use.

　　 generally use ABS resin tool has excellent gloss degree, molding property and resistant impact property and other this features, is due to it in combined formed ABS use butadiene in is has di structure, therefore especially easy by hot can and outer 线进行 separation understanding oxidation. in weather resistance long use AES resin 时候, 就会出现变 color and material property reduce 情况. although this type of issues can through using/adopting additives solution, is stabilizer for resin long stability property can function is has 限, therefore solution this type of issues most 根本 办 method is use has has di structure stability property 橡胶.

　　于此 meanwhile, AES resin not only is types weather resistance resin, but also due to AES resin has ratio ASA more add excellent low temperature resistance impact property can features, therefore AES resin by use to lifespan long, safety can plastics products and automotive parts production in.

AES resin if need coating 装 话, it in price upper more tool has competition force. especially is in electronics field/area, AES weather resistance also can long use, but also in use also can more good maintain products has new 鲜亮丽 color color.

AES injection molding process

drying conditions: 80~85℃( heat resistant AES:90-100℃) lower most less drying 3-4 small 时; AES材 material tool has wet property, requirements in processing front drying 处理; material wet degree ensure small 于0.1%.

processing temperature degree: 200~260℃,   heat resistant AES temperature degree improve/increase 10℃, in high temperature inner time long （应 small 于30 separation 钟）;

mold temperature degree: 40…80℃;

injection pressure: 500~800bar;

injection speed degree: in high speed degree;

screw back pressure: 10-40bar.
