Shanghai Daoqin Plastics Co., Ltd.

        1.SA property can: 

         chemical and material features: SA is types hard, transparent material,不 easy generate internal stress cracking. transparent degree very high, its soft temperature degree and impact resistant strong/high degree ratio PS high. styrene formed make SA坚 hard, transparent easy processing; acrylonitrile formed make SA tool has chemical stability property and heat stabilized property. SA tool has very strong/high 承受载荷 can force, resistant chemical reaction can force, resistant hot deformation features and stability property.

        SA in add glass fiber additives can increase strong/high degree and resistant hot deformation can force, decrease small thermal expansion coefficient. SA Vicat softening temperature is 110℃. lower deformation temperature degree is 100C,SA shrinkage rate is 0.3~0.7%.

        2.SA process features:

        SA processing temperature degree generally in 200-250℃ is 宜. material easy wet, processing front drying small above, its flow property ratio PS稍差一点, injection pressure high (injection pressure: 350~1300bar), injection speed degree: use high speed injection. mold temperature control in 45-75℃ relatively good. drying 处理: if 储存不适当, SA has 一 吸 wet features.

        建议 drying conditions is 80℃, 2~4 small 时. temperature degree: 200~270℃. if processing thick products, can use low lower 限 熔化 temperature degree. for/regarding reinforcement type material, mold temperature degree need ultra- 60℃. cooling system must very good design, is mold temperature degree will effect/influence products appearance, shrinkage rate and bending. runner and gate: has gate can use. gate dimensions must very 恰当, 以避免 generate strip/profile 纹, and 空隙.

        3． typical applications scope/range:

         electrical (插 base/seat, housing/shell and other), day use product (厨房 device 械, plant/unit, electrical machine base/seat, belt/tape box/case and other), automotive industrial (车头灯 box/case, light 境, table/sheet and other), use product (餐 tool, food tool and other), product packaging safety 玻璃, water device outer housing/shell and water leading 旋扭.

         medical grade products (injection device, liquid tube/pipe, 肾渗折 plant/unit and reaction device). packaging materials (化妆 box/case, sleeve/set tube/pipe, 睫毛膏 cover/cap bottle 子, cover/cap, cover/cap device and nozzle and other), product (one-time property machine outer housing/shell, 刷子基材 and hard 毛, tool, false 牙, 牙刷柄, 笔杆, device tube/pipe and toward Monofilament) and other.
