以聚丙烯 (PP)、乙烯醋酸乙烯共聚物 (EVA) 或低密度聚乙烯 (PE) 为基础的色母料最适合 Dynaflex™ G7650-1(天然)着色。使用熔体流动速率较高(范围为 25 - 40 克/10 分钟)的色母料,则能达到较好的颜色分散效果。典型的色母料用量为 1% 至 5%(重量)。不应采用以 PVC 为基础的色母料。色母料是否适用,应由用户通过试验来最终确定。在使用此产品之前或之后,均须用熔体流动速率较低 (0.5 - 2.5 MFR) 的聚乙烯 (PE) 或聚丙烯 (PP) 彻底进行置换。Dynaflex™ G7650-1(天然)可利用高达 20% 的回收料同时其性能所受影响却极小,但该回收料必须是未受到污染的。为了最大限度地减小模塑期间其性能所受的影响,熔体温度应维持得尽可能低。回收料的有效性应由用户最终确定。Dynaflex™ G7650-1(天然)具有极好的熔体稳定性。最长停留时间可能会根据机筒尺寸有所变化。通常,如果机器闲置 8 - 10 分钟或以上,则应将机筒排空。不需要干燥注射速度:1 - 3 英寸/秒第一阶段 - 提升压力:250 - 800 psi第二阶段 - 保持压力:30% 的升压保持时间(厚部件):3 - 10 秒保持时间(薄部件):1 - 3 秒 |
