HPMC for Gypsum An Essential Additive in Construction

Applications in Construction and Other Industries

- Increased Construction Activities The rapid urbanization and infrastructural development in China have led to heightened demand for construction chemicals, including HPMC. Government initiatives aimed at boosting housing and infrastructure projects have further accelerated this trend.

The production of HPMC involves a series of chemical processes. First, natural cellulose is extracted from plants, usually derived from wood pulp or cotton. The cellulose is then treated with alkali to facilitate the etherification reaction, where the hydroxypropyl and methyl groups are introduced. The end product is then purified, dried, and milled into a fine powder form. This meticulous process ensures that HPMC retains its functional properties and quality for various applications.

3. Film-Forming Ability The polymer possesses excellent film-forming properties, allowing it to create robust barriers when applied to surfaces. This capability is especially beneficial in the cosmetic industry, where it is used in products like foundation and skincare formulations.
