When the formulation is applied to a substrate, the water evaporates, and HPMC forms a continuous film on the surface. This film provides adhesion, cohesion, and improved workability to the construction material. The thickening property of HPMC is a result of its long and flexible polymer chains, which entangle and interact with other particles in the formulation, leading to increased viscosity.
2.1 Data
Methyl cellulose and HPMC are two types of cellulose-based polymers commonly used in building materials. However, Methyl Cellulose is gradually being replaced by HPMC due to the higher requirements in modern construction. In addition, some suppliers refer to methyl cellulose as the common name for hydroxypropyl methyl cellulose (HPMC) and Hydroxyethyl methyl cellulose (HEMC). We will explore the difference between HPMC and HEMC in later articles.
Uses
Are HPMC Capsules Natural?

hpmc ltd. HPMC can improve the hardness, disintegration, and drug release of tablets, making it a valuable ingredient for pharmaceutical manufacturers. It is also used in ophthalmic preparations, topical creams, and suspensions due to its thickening and stabilizing properties.
(6) Polyvinyl chloride: As dispersant in the production of polyvinyl chloride, it is the main assistant in the preparation of PVC by suspension polymerization.


In the construction sector, HPMC gel is added to tile adhesives to improve their workability, water retention and bonding properties. It ensures a consistent and strong bond between the tile and the substrate.
Choosing HPMC over other binders offers important advantages for specific consumer groups:
