Etherification Synthetic Principle of Hydroxypropyl Methyl Cellulose (HPMC)
Hydroxypropyl methylcellulose ((HPMC), raw cellulose, can be refined cotton or wood pulp, it is very necessary to crush it before alkalization or during alkalization, and the crushing is through mechanical energy Destroy the aggregate structure of cellulose raw materials to reduce the degree of c...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 -
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 -
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 -
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 -
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 -

The important role of cellulose ether in mortar
Cellulose ether can significantly improve the performance of wet mortar, and is a main additive that affects the construction performance of mortar. Reasonable selection of cellulose ethers of different varieties, different viscosities, different particle sizes, different degrees of viscosity and...Read more -
The role of cellulose ether in ready-mixed mortar
In ready-mixed mortar, the addition amount of cellulose ether is very low, but it can significantly improve the performance of wet mortar, and it is a main additive that affects the construction performance of mortar. Reasonable selection of cellulose ethers of different varieties, different visc...Read more -
Application of Cellulose Ether in Food
For a long time, cellulose derivatives have been widely used in the food industry. Physical modification of cellulose can adjust the rheological properties, hydration and tissue properties of the system. The five important functions of chemically modified cellulose in food are: rheology, emulsifi...Read more -
What is the role of hydroxyethyl cellulose in coatings!
What is Hydroxyethyl Cellulose? Hydroxyethyl cellulose (HEC), a white or light yellow, odorless, non-toxic fibrous or powdery solid, prepared by etherification reaction of alkaline cellulose and ethylene oxide (or chlorohydrin), belongs to Nonionic soluble cellulose ethers. Since HEC has good pro...Read more -
Application of Hydroxyethyl Cellulose (HEC) in Latex Paint
Thickeners for latex paints must have good compatibility with latex polymer compounds, otherwise there will be a small amount of texture in the coating film, and irreversible particle aggregation will occur, resulting in a decrease in viscosity and coarser particle size. Thickeners will change th...Read more
