3. Construction HPMC is an essential component in construction materials, particularly in tile adhesives, plasters, and dry mortars. It enhances the workability, water retention, and adhesion of these materials, making them easier to apply and improving their final performance.


Composition and Properties


4. Ophthalmic Solutions HPMC E50 is also used in ophthalmic preparations due to its ability to provide lubrication and moisture retention, enhancing patient comfort.


Molecular weight refers to the mass of a molecule, typically expressed in Daltons (Da) or grams per mole (g/mol). In the case of HPMC, its molecular weight is influenced by the degree of polymerization, which is the number of repeating units in the polymer chain. HPMC is synthesized from cellulose, and during this process, hydroxypropyl and methyl groups are introduced. The ratio of these groups, along with the degree of polymerization, determines the overall properties of HPMC.

In tiling applications, PVA for tiling serves as a crucial additive that enhances the bonding strength between the tiles and the substrate. When used in tile adhesives, polyvinyl alcohol powder creates a stronger and more flexible bond, allowing for better adhesion, especially in areas that experience temperature fluctuations or moisture exposure. This improved bond reduces the likelihood of tiles cracking or coming loose over time, ensuring a longer-lasting and more durable surface.
