General description

羟丙基甲基纤维素(HPMC)是水溶性聚合物，是纤维素的衍生物。这种多聚糖溶于水中会形成胶体。羟丙甲纤维素是由天然物质经人工制备而成的亲水胶体。甲氧基含量28-30%，羟丙基含量7-12%。

Application

水和非水系统的增稠剂、具有抗脂性的透明薄膜、粘合剂、润滑剂、空间稳定剂和保水剂。
羟丙基甲基纤维素(HPMC)已用于：
  • 作为制备印刷油墨的粘度改性剂
  • 作为制备羟磷灰石(HAP)的增黏剂
  • 制备羟丙基甲基纤维素凝胶及复合体凝胶

Biochem/physiol Actions

羟丙基甲基纤维素(HPMC)可作为悬浮助剂、表面活性剂、润滑剂、保护性胶体和乳化剂。此外，HPMC聚合物的溶液形式具有热凝胶性，常用作粘合剂、增稠剂、成膜剂和保水剂。羟丙甲纤维素还具有表面活性。

Features and Benefits

溶于水，加热后可逆凝胶化，非离子，不与离子组分络合，具有表面活性和抗酶活性。溶液为假塑性。
