Hydroxypropyl methylcellulose can be divided into cold water instant type and hot melt type, co...Read more -
What factors will affect the viscosity of hydroxypropyl methylcellulose?
For the application of wet mortar, hydroxypropyl methylcellulose has good thickening properties, can significantly increase the bonding ability between wet mortar and the base layer, and can also improve the anti-sag performance of mortar, so it is widely used in plastering Mortar, external wall ...Read more -
What does a good hydroxypropyl methylcellulose ether HPMC look like?
In putty, cement mortar and gypsum-based slurry, HPMC hydroxypropyl methylcellulose ether mainly plays the role of water retention and thickening, and can effectively improve the adhesion and sag resistance of the slurry. Factors such as air temperature, temperature and wind pressure speed will a...Read more -
Effect of Hydroxypropyl Methyl Cellulose Ether (HPMC) on the Water Holding Capacity of Powder
Hydroxypropyl methylcellulose (HPMC) mainly plays the role of water retention, thickening and improving construction performance in cement, gypsum and other powder materials. Excellent water retention performance can effectively prevent the powder from drying and cracking due to excessive water l...Read more -
Application example of CMC in acidic milk drink
1. Theoretical basis It can be seen from the structural formula that the hydrogen (Na+) on CMC is very easy to dissociate in aqueous solution (generally exists in the form of sodium salt), so CMC exists in the form of anion in aqueous solution, that is, it has a negative charge and is amphoteric....Read more -
Sodium carboxymethyl cellulose (CMC) as a food thickener
Sodium carboxymethyl cellulose (also known as: sodium carboxymethyl cellulose, carboxymethyl cellulose, CMC, Carboxymethyl, Cellulose Sodium, Sodium salt of Caboxy Methyl Cellulose) is the most widely used and the largest amount used in the world today types of cellulose. CMC-Na for short, is a c...Read more -

Hydroxypropyl methyl cellulose, do you know?
1.HPMC is divided into instant type and fast dispersion type. The HPMC fast dispersion type is suffixed with the letter S, and glyoxal must be added during the production process. HPMC instant type does not add any letters, such as “100000″ means “100000 viscosity. 2. With or wi...Read more -
How is the trend of Cellulose ether?
Cellulose ether is made from cellulose through the etherification reaction of one or several etherification agents and dry grinding. According to the different chemical structures of ether substituents, cellulose ethers can be divided into anionic, cationic and nonionic ethers. Ionic cellulose et...Read more -
