Hydroxypropyl Methylcellulose

Hydroxypropyl Methylcellulose (HPMC for short) is an important chemical and building material additive obtained by chemical modification of natural cellulose, which has a variety of excellent physical and chemical properties and application characteristics.

The main properties of HPMC powder are as follows.

Good solubility: HPMC has good solubility and swelling in water, which can be fully dispersed and dissolved in cement-based, lime-based, gypsum-based and other cement-based materials, increasing the fluidity and processability of the materials.

Good viscosity adjustment ability: The viscosity of HPMC can be adjusted according to different production processes and application requirements, which can control its fluidity and processability in cement-based materials, and also improve its crack resistance and durability.

Excellent water retention: HPMC has good water retention and moisture retention properties, which can slow down the evaporation of water and maintain the water content of cementitious and other materials, which is conducive to the early strength development and crack resistance improvement of materials.

Good surface activity and dispersibility: HPMC contains hydroxyl and methyl groups in its molecules, which have good surface activity and dispersibility and can effectively disperse and stabilize tiny particles, such as air bubbles and particle impurities, in cementitious and other materials.

Good biocompatibility: HPMC is a natural cellulose derivative with good biocompatibility and non-toxicity, which will not cause harm to the environment and human health.

HPMC has a wide range of applications, mainly in construction materials, food, pharmaceuticals, cosmetics and other fields. In the field of construction materials, HPMC is mainly used in cement mortar, wall coatings, waterproof materials, tile adhesives and other materials, which can improve the fluidity, processing properties, anti-cracking properties and durability of materials, and improve the quality and service life of materials.
