| Dynaflex™ G7930-1 NSFG can be recycled as a filler or impact modifier for polyolefins, or can be recycled by grinding and reintroduction to the molding process. Similar to PP or PE recycling process, if separated appropriately, it can be recycled many times.Municipality waste stream recycle code is "7" which is designated for "Other".Please contact GLS Thermoplastic Elastomers for a copy of our Recyclability Compliance letter. |

| 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™ G7930-1 NSFG 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）。可以使用液体颜料，但以矿物油为基础的载体对最终硬度值会有显著的影响。不应采用以 PVC 为基础的色母料。若使用 GLS 可供的预着色复合材料，则可达到较好的配色一致性。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™ G7930-1 NSFG 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™ G7930-1 NSFG 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：200 - 900 psi第二阶段 - 保持压力：50% 的升压保持时间（厚部件）：3 - 10 秒保持时间（薄部件）：1 - 3 秒 |
