一般描述
聚[4,4′-亚甲基双(异氰酸苯酯)-alt-1,4-丁二醇/二(丙二醇)聚己内酯] (PU/PCL)是一种聚氨酯溶液，可用作形状记忆聚合物和增强基材力学和热性能的增强质。它具有生物相容性，可用于内皮细胞增殖。聚己内酯型聚氨酯 (PU/PCL) 含有聚己内酯 (PCL)，可提高聚合物基质的疏水性。
应用
PU/PCL可用于制备聚氨酯膜，用于有效的气体分离。它还可用于合成具有良好热力学特性的生物医学用增强水凝胶。
汽车仪表板、电缆护套、侧壁衬里、织物层压材料、医疗管材、导液管、透皮贴片，并用于调味瓶密封件、鞋、轴衬和车轮。
特点和优势
具有良好的透明度、耐化学性、柔韧性和韧性的耐用耐磨高性能弹性体。可使用当前形式的产品，也可将产品进一步聚合化后使用。低压缩形变
