General description
聚[（异氰酸苯酯）-共甲醛]（P-MDI）是一种扩链剂，每个异氰酸酯基均连接一个苯基。它是一种液态聚合物，用于在固化过程中保持不同聚合物单元之间交联反应的均匀性。它的交联位点（−NCO）使其可用于制备聚氨酯。
Application
P-MDI是一种异氰酸酯，可用于制备聚氨酯树脂、薄膜和泡沫。它可以形成高机械强度的、耐溶剂的膜，并可用作生物材料应用中的OTFT电极。
PPIF可与二醇共混以形成具有−NCO特征峰的聚氨酯混合物。它也可用作形成高拉伸强度介电材料的交联剂，该材料有望用于有机电子学领域。
Features and Benefits
高粘度、高官能度低聚物。
