Top 4 Tips About HPMC Solubility
December 18th 2024
HPMC is a kind of cellulose ether which could be used in many application, such as in construction industry, food industry, pharmacy industry, daily chemical industry, and plays very important roles in building material, such cement mortar, tile adhesive, gypsum-based plaster, detergent and so on, and it will be critical for you to know how is the quality of the HPMC if you need to purchase it. Now, let me tell you four easy tips to judge the quality, and could do some tests if you have some lab equipment.
The whiter the better, the color is usually related to raw materials and purity, it has not too much influence on the use of the product, but if you have a better chance, why not choose the better one
The finer the better. Fineness is also an important performance indicator for cellulose ether. Fineness affects the solubility of cellulose ether. Only enough fine powder can avoid cellulose ether agglomeration when adding water.
the better the transmittance is, the better the HPMC is. A transparent colloid will be formed if the HPMC is added into water, then you can compare the transparency of different samples. And Transmittance will be an important performance indicator if HPMC is applied in detergent and shampoo.
The greater the specific gravity is, the better the HPMC is better. Because specific is related to the content of hydroxypropyl group, and if the content of hydroxypropyl group is high, the water retention is better
