Lustran® ABS 648

丙烯腈丁二烯苯乙烯

INEOS ABS (USA)

产品说明：

Lustran ABS 648 resin is a general-purpose injection molding grade of ABS (acrylonitrile butadiene styrene). It is a high-impact, high-gloss resin with a good balance of physical properties and easy flow to enhance moldability.

Lustran ABS 648 is used in applications requiring extra toughness. It is well-suited for complex part designs with difficult-to-fill molds. Lustran ABS 648 is used in home appliances for floor care housings, vacuum cleaner housings, and kitchen electrical appliance housings; lawn and garden applications; and electric power tool housings. It is also used in irrigation parts and electrical utility boxes. Per the restrictions of the Consumer Product Safety Improvement Act (CPSIA) that went into effect on February 10, 2009, Lustran ABS 648 can not be used to manufacture children's toys or child care articles. As with any product, use of Lustran ABS 648 resin in a given application must be tested (including field testing, etc.) in advance by the user to determine suitability.

制备方法

ABS的生产方法很多，可分为掺合法，接枝法，联用法个接枝-掺合法四大类，约十一种制备工艺。如今大多采用的是乳液法，当前最有广阔前途的是乳液接枝法。ABS通过改变三种单体的比例和采用不同聚合方法，可制得各种规格产品，其结构有以弹性为主链的接枝共聚物和以树脂为主链的接枝共聚物，一般三种单体 的比例范围大致为丙烯腈 25%~35%，丁二烯25%~30%和苯乙烯40%~50%。

由于PC/ABS是两种聚合物的共混，又以PC为主，在加工制品时，有时还会在浇口处出现斑纹现象，通常是由于高速注射时，熔料扩张进入模腔造成。熔体破裂所致。从成型工艺方面入手，可以采取提高物料温度，提高喷嘴温度，减慢注射速度等措施来减少PC/ABS制品斑纹的出现，也可以提高模具温度，增设增滥槽，增加浇口尺寸，修改浇口形状等来解决。例如对大型薄壁制件采用扇形浇口，也可以采用耳形浇口，在浇口出口处增设一个耳槽，使浇口附近的喷射，料流冲击斑痕，以及残余应力都集中在耳槽，而不影响PC/ABS制件质量。同时，由于多个浇口注塑或者分流道多时，也会出现熔接线。
