Hydroxypropyl Methyl Cellulose (HPMC) is also named as MHPC, are types of non-ionic cellulose ether, which are a powder of white to off-white color, that function as a thickener, binder, film-former, surfactant, protective colloid, lubricant, emulsifier, and suspension and water retention aid. In addition, these types of cellulose ethers exhibit properties of thermal gelation, metabolic inertness, enzyme resistance, low odor and taste, and pH stability. HPMC are widely used in construction,pharmaceutical,food,cosmetic,detergent,paints,textiles etc.We can provide the general grade HPMC, we also designed the modified HPMC according to customer requirements. After modified, we can get the product which have long open time, good anti-sagging,good workability etc.
Protection from water exudation and material sedimentation.
No effect on slurry fluidity with low viscosity
HPMC, while its water retention characteristics improve the finish performance on the surface.
6. A simple test method for the ash content of cellulose ether: weigh one to two grams of cellulose ether, ignite it with a lighter, weigh the ash residue left by the combustion of cellulose ether, and when the ash residue / cellulose ether is ≥ 5%, the quality of cellulose ether is basically unqualified. (there are sometimes errors in this method. First, the manufacturer compounded the products suitable for specific customers for customers before leaving the factory; second, the agents or manufacturers added flammable substances with low ash content when adulterating)
Methyl Hydroxyethyl Cellulose is a white, yellow-white or off-white powder or granules, hygroscopic after drying. It is a methylcellulose based cellulose. It has several properties used in the pharmaceutical and construction industries. Methyl Hydroxyethyl Cellulose (MHEC) alone or in combination is the most widely used cellulose in mortar formulations. MHEC has various properties such as thickening, emulsifying, binding, forming, protective colloid and water retention.
