AS resin Scientific Names is acrylonitrile - styrene copolymer (acrylonitrile-styrene copolymer).由 acrylonitrile and styrene copolymer formed polymer/macromolecule combined material. generally styrene 15%-50%. transparent belt/tape color 至琥珀针 color solid 体. density 1.06. has thermoplastic property. easy color. dilute acid, dilute alkali, dilute alcohol and effect/influence. solvent ketone, acid ester, chlorine ethylene and other in. can used as engineering plastics. tool has excellent heat resistant property and resistant solvent agent property. used for made oil resistant machine parts, table/sheet housing/shell, table/sheet 盘, battery box/case, machine 油箱, battery outer housing/shell, packaging container, day use product and other. can formed Monofilament. main/primary used as production ABS resin mixed material.  

AS resin material 质概况

acrylonitrile - styrene copolymer is acrylonitrile and styrene through method, method or emulsion method made. transparent or semi transparent water white pellets. versus for density 1.06-1.08. rate 1.57. balanced water property 0.66%. heat deflection temperature (HDT) 82-105℃. tool has high gloss, high transparency, high impact, good heat resistant property and mechanical properties. rigid property large, tool has relatively high chemical stability property, resistant water, oil resistant, resistant acid, resistant alkali, resistant alcohol type. solvent ketone type solvent agent and certain 芳烃, chlorine 代烃. weather resistance in and other, property relatively large.

tensile strength:72-78MPa

impact strong/high degree:2.1-2.5kJ/m2

洛氏 hardness:R76-80

melt 指数:l. 4-3.3g/10min

SAN(AS) ratio polystyrene (PS) has more high impact strong/high degree and excellent heat resistant property, oil resistant property, chemical resistant property. it can very good resistant certain make polystyrene (PS) force cracking type. elastic property modulus is has thermoplastic property plastics in relatively high types.

AS is styrene - propylene copolymer 体, easy generate internal stress cracking. transparent degree very high, its soft temperature degree and impact resistant strong/high degree ratio PS high.

AS resin material property can

SAN(AS) tool has very strong/high 承受载荷 can force, resistant chemical reaction can force, resistant hot deformation features and stability property. SAN(AS) in add glass fiber additives can increase strong/high degree and resistant hot deformation can force, decrease small thermal expansion coefficient. SAN(AS) Vicat softening temperature is 110℃. lower deformation temperature degree is 100℃. SAN(AS) shrinkage rate is 0.3-0.7%. SAN(AS) is types hard, transparent material. styrene formed make SAN(AS)坚 hard, transparent easy processing; acrylonitrile formed make SAN(AS) tool has chemical stability property and heat stabilized property.

AS resin injection molding process

AS 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 一. drying if 储存不适当, SAN(AS) has 一 吸 wet features. drying conditions is 80℃, 2-4 small 时.

熔化 temperature degree 200-270℃. if processing thick products, can use low lower 限 熔化 temperature degree.

mold temperature degree 40-80℃. 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.

injection pressure 350-1300bar injection speed degree use high speed injection

runner and gate has gate can use. gate dimensions must very 恰当, 以避免 generate strip/profile 纹, and 空隙.

AS resin application scope

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 and other. used for made as oil resistant, heat resistant, chemical resistant product industrial products, and table/sheet sheet/plate, table/sheet frame, housing/shell, battery box/case, box/case, multiple and and other.
