This product include Hydroxypropyl Methyl Cellulose(HPMC)of pharmaceutical grade and industrial grade.
1. Pharmaceutical grade: this product is mainly used for pharmaceutic adjuvant that can be used as a thickener, dispersing agent, emulsifier and film-forming agent etc. When used as film coating and adhesive in drug tablets, it can significantly improve the waterproofing of tablets. Besides, it can also be used as suspension, ophthalmic preparation, slow and controlled release agent skeleton and floating tablets etc.. HPMC is combined with colloidal drugs as other synthetic polymers in order to prevent the separation of water and ethanol from transparent water and colloidal materials and improve water retention; and it is also used in food, cosmetics and other fields as thickener, emulsifier and to improve the rheological properties as well as other daily chemical industries, etc.
2. Industrial grade: industrial grade HPMC is mainly used as dispersant in PVC production and is also the main additive of PVC preparation for suspension polymerization. In building construction, it is mainly used for external wall thermal insulation system, thermal insulation mortar, decoration mortar, masonry mortar and selfleveling mortar etc.. It is used as thickener, stabilizer, emulsifier, excipient, water retaining agent, filmforming agent etc. in the production of petrochemical products,paint remover, agricultural chemicals, printing ink, textile printing and dyeing, ceramics, papermaking, cosmetics and other products. When it is applied to synthetic resin, the products obtained will be of characteristics such as regular and loose particles, suitable apparent specific gravity and good processing properties etc., which can essentially replace gelatin and polyvinyl alcohol as dispersant.
