Uses:
1. textile and dyeing industry
HPMC used in textile and dyeing industry as sizing agent and dying adjuvant to make stock limpidity and transparence. It is easy a good stabilizer of the stock and helps to form film. It is easy to desizing.
2.construction industry
HPMC are widely used to improve the performance of hydrogel construction materials such as cement and gypsum. In cement-based mortar, it can increase water retention, and to extend the opening and correcting hours and reduce sagging.
3. Industry grade
It is widely used as thickener, adhesive, water retention agent, film-forming agent,.
4. pharmaceuticals industry
The product is a medical accessory material. It can be used for densifiers, dispersing reagent, emulsifying reagent,lubricator and former etc. It's used as an adhesive and coating film in tablets, increasing markedly rate of dissolution and release,and strengthen water proof for tablets and also be used as mixed dispersing reagent ,eye drop reagent,controlled released matrix tablets,It is combined with other synthetic polymers and gel-type drug products to prevent ethanol separated from transparent gel drug while improve water keep ability.
