Introduction to the basic properties of pharmaceutical grade HPMC
1. The basic properties of HPMC Hypromellose, English name hydroxypropyl methylcellulose, alias HPMC. Its molecular formula is C8H15O8-(C10Hl8O6)n-C8Hl5O8, and its molecular weight is about 86000. This product is a semi-synthetic material, which is part of methyl and part of polyhydroxypropyl eth...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 -
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 -

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 -
