    The glass transition temperature is the temperature range at which a polymer transitions from a brittle, glassy state to a more flexible, rubbery state. This transition is not a sharp change but rather a range of temperatures over which the material's properties gradually change. For HPMC, Tg is particularly significant as it directly influences the polymer's mechanical properties, solubility, and stability.

    In the construction industry, HPMC is used to improve cement-based materials’ workability, adhesion, and durability. As a water retention agent, it prevents rapid water loss during curing. And it improves the strength and durability of the final product. HPMC also acts as a thickener and binder, improving the workability and adhesion of the mortar or grout.
