商品详细描述
本品为非离子型纤维素醚,外观为白色的粉末,无嗅无味,溶于水及大多数极性有机溶剂和适当比例的乙醇/水、丙醇/水、二氯乙烷等,在乙醚、丙酮、无水乙醇不溶,在冷水中溶胀成澄清或微浊的胶体溶液。水溶液具有表面活性,透明度高、性能稳定。HPMC具有热凝胶性质,产品水溶液加热后形成凝胶析出,冷却后又溶解,不同规格的产品凝胶温度不同。溶解度随粘度而变化,粘度越低,溶解度越大,不同规格的HPMC其性质有一定差异,HPMC在水中溶解不受PH值影响。颗粒度:100目通过率大于100%。堆密度:0.25-0.70g/ (通常0.4g/ 左右),比重1.26-1.31。变色温度:180-200℃,炭化温度:280-300℃。HPMC具有增稠能力,排盐性、PH稳定性、保水性、尺寸稳定性、优良的成膜性以及广泛的耐酶性、分散性和粘结性等特点。 ![](http://imgupload.yihubaiying.com/imagestore20160427199a6fae-8ebb-43c6-ae90-b338f7c4a1fb.jpg)
