Hypromellose, also commonly known as hydroxypropyl methycellulose (HPMC) is a coating agent and film-former used as an inactive ingredient in the pharmaceutical industry. It has also been used as a rate-controlling polymer for sustained-release dose forms.
Hydroxypropyl Methyl Cellulose (HPMC) are widely used in construction, pharmaceutical,food, cosmetic,detergent,paints,as thickener, emulsifier, film-former, binder, dispersing agent, protective colloids.We can provide the regular grade HPMC, we also can provide modified HPMC according to customer requirements. After modified and surface treatment, we can get the goods which is dispersed in water quickly, lengthen open time, anti-sagging, etc.
Hydroxypropyl methyl cellulose (HPMC) is a natural polymer materials as raw materials,through a series of chemical processing and prepared non-ionic cellulose. It contains almost methyl cellulose(MC) of all the performance, your first choice for production of high quality building materials additives.To meet the needs of environmental protection, Our product with high water retention, dispersion, good fineness, good work ability, easy dissolution characteristics.It suitable for dry mortar building, both inside and outside wall putty powder milk (cream), adhesives, caulks, interface agents, coatings, self-leveling agent of new building materials.
Regarding HPMC questions and answers 6. What is the proper viscosity of hydroxypropyl methylcellulose (HPMC)? ——Answer: Generally 10W is enough for putty powder, and the requirement for mortar is higher, and 15W-20W is better. Moreover, the most important role of HPMC is water retention, followed ...
3. What are the dissolution methods of hydroxypropyl methylcellulose (HPMC)?——Answer: Hot water dissolution method: Since HPMC does not dissolve in hot water, HPMC can be uniformly dispersed in hot water at the initial stage, and then quickly dissolve during cooling. Two typical methods are describe
