HPMC (Hydroxypropyl methylcellulose) is generally used in putty powder with a viscosity of 100,000 mPa.s(NDJ), while mortar requires a relatively high viscosity and should be selected with a viscosity of 150,000mPa.s to achieve the desired effect. The most important role of HPMC is water retention and thickening secondly. Therefore, in putty powder, it is okay […]

The use of cellulose ether HPMC in external thermal insulation mortar: cellulose ether plays a role of bonding and increasing strength in this material. The sand will be easier to coat, improve work efficiency, and have the effect of anti-sagging. Higher water retention performance can extend the working time of the mortar, improve shrinkage resistance and crack resistance, improve surface quality, and increase bonding strength.

1. What are the main uses of hydroxypropyl methylcellulose (HPMC)? HPMC is widely used in construction materials, coatings, synthetic resins, ceramics, pharmaceuticals, food, textile, agriculture, cosmetics, tobacco and other industries. HPMC can be divided into construction grade, food grade and pharmaceutical grade according to its usage. Currently, most Chinese domestic production is at the construction […]

Why HEMC is the better choice than HPMC for manufacturing of Cement tile adhesive and Wall putty?

Water-retaining and Principle of HPMC

HPMC, which is uniformly reacted, has even distribution of methoxy and hydroxypropoxy groups and high water retention.

1, this method is suitable for the determination of the dynamic HPMC viscosity of non-Newtonian fluids (polymer solution, suspension, emulsion dispersion liquid or surfactant solution, etc.).

In dry mix mortar, Adding a little HPMC can significantly improve the performance of wet mortar. It can be seen that HPMC is a major additive that affects the construction performance of mortar.

Hydroxypropyl methyl cellulose HPMC is a non-ionic cellulose ether made from natural polymer material cellulose through a series of chemical processing. They are an odorless, tasteless and non-toxic white powder that swells into a clear or slightly turbid colloidal solution in cold water.
