4. Construction HPMC dispersions play a vital role in the construction industry, particularly in the formulation of tile adhesives, renders, and dry mortars. The addition of HPMC improves the workability and adhesion of these materials, ensuring better performance and durability in various building applications.

The glass transition temperature for HPMC varies based on its molecular weight and substitution level. Generally, lower molecular weight grades of HPMC exhibit lower Tg values compared to their high molecular weight counterparts. This variance arises because lower molecular weight materials possess fewer entanglements among polymer chains, leading to enhanced molecular mobility at lower temperatures. As a result, the Tg of HPMC can range from approximately 50°C to 120°C. Understanding this range enables manufacturers to select the appropriate grade of HPMC for specific applications, ensuring the material performs effectively under operational conditions.

2. Pharmaceuticals In the pharmaceutical industry, hydroxyethyl cellulose serves as a binder and thickening agent in tablets and ointments. It is often utilized in controlled-release formulations, where it aids in the gradual release of active ingredients. HEC is also incorporated into formulations to improve suspensions of insoluble drugs, enhancing their effectiveness.
