ABS Lustran LK197

Lustran? ABS LK197 resin is a high-gloss, medium-impact extrusion grade of ABS (Acrylonitrile Butadiene Styrene). It provides a superior balance between rigidity and impact strength, as well as excellent melt strength for good thermoformability. It is easy to color with ABS color concentrates. Lustran? ABS LK197 resin is used for applications that require high gloss and higher rigidity, such as bathtubs, sinks, and shower surrounds for recreational vehicles, and interior liners for ice chests and picnic coolers.

成型性能

无定形材料,流动性中等,吸湿大,必须充分干燥,表面要求光泽的塑件须长时间预热干燥80-90度,3小时；

宜取高料温,高模温,但料温过高易分解(分解温度为270度).对精度较高的塑件,模温宜取50-60度,对高光泽.耐热塑件,模温宜取60-80度；

如需解决夹水纹，需提高材料的流动性，采取高料温、高模温，或者改变入水位等方法；

如成形耐热级或阻燃级材料，生产3-7天后模具表面会残存塑料分解物，导致模具表面发亮，需对模具及时进行清理，同时模具表面需增加排气位置；

冷却速度快，模具浇注系统应以粗，短为原则，宜设冷料穴，浇口宜取大，如：直接浇口，圆盘浇口或扇形浇口等，但应防止内应力增大，必要时可采用调整式浇口。模具宜加热，应选用耐磨钢；

料温对塑件质量影响较大，料温过低会造成缺料，表面无光泽，银丝紊乱料温过高易溢边，出现银丝暗条，塑件变色起泡；
