MHEC is one of the key materials used to improve the application behavior of cement tile adhesive. It supports water retention, bonding strength, thickening, and workability.

The key difference between HPMC and MHEC lies in their gel temperature. The gel temperature of HPMC is generally around 60–75℃, depending on the group content and production process, whereas the gel temperature of MHEC is usually above 80℃.

Polyvinyl Alcohol 2488, commonly known as PVA 2488, is one of the most widely used water-soluble polymers in industries such as construction chemicals, textile sizing, paper processing, adhesives, coatings, ceramics, emulsions, and packaging.

Polyvinyl alcohol itself is not produced directly from vinyl alcohol monomers because vinyl alcohol is chemically unstable. Instead, PVA is manufactured through the hydrolysis or alcoholysis of polyvinyl acetate.
