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 -
Hydroxypropyl methyl cellulose ether (HPMC) for dry powder mortar
The Chinese name of HPMC is hydroxypropyl methylcellulose. It is non-ionic and is often used as a water-retaining agent in dry-mixed mortar. It is the most commonly used water-retaining material in mortar. The production process of HPMC is mainly a polysaccharide-based ether product produced by a...Read more -
Application of Cellulose Ether in Hot Melt Extrusion Technology
Joseph Brama invented the extrusion process for the production of lead pipes in the late 18th century. It was not until the middle of the 19th century that hot-melt extrusion technology began to be used in the plastics industry. It was first used in the production of insulating polymer coatings f...Read more -
Properties of Hydroxypropyl Methyl Cellulose Ether in Mortar
As one of the important cellulose ether admixtures in dry powder mortar, hydroxypropyl methylcellulose has many functions in mortar. The most important role of hydroxypropyl methylcellulose in cement mortar is water retention and thickening. In addition, due to its interaction with the cement sys...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 -
Etherification Synthetic Principle of Hydroxypropyl Methyl Cellulose (HPMC)

Proportion and Application of HPMC in Machine-blast Mortar
The mechanized construction of mortar has been tried and promoted for many years in China, but no substantial progress has been made. In addition to people’s skepticism about the subversive changes that mechanized construction will bring to traditional construction methods, the main reason ...Read more -
Hydroxypropyl methyl cellulose ether for construction
Product characteristics of hydroxypropyl methylcellulose for construction Soluble in water and some organic solvents. Can be dissolved in cold water. Its maximum concentration only depends on the viscosity. The solubility changes with the viscosity. The lower the viscosity, the greater the solubi...Read more -
Introduction to the basic properties of pharmaceutical grade HPMC

This product is a semi-synthetic material, which is part of methyl and part of polyhydroxypropyl eth...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 -
CMC application characteristics and process requirements in food
The use of CMC has many advantages over other food thickeners: 1. CMC is widely used in food and its characteristics (1) CMC has good stability In cold foods such as popsicles and ice cream, the use of CMC can control the formation of ice crystals, increase the expansion rate and maintain a unifo...Read more
