Before diving into viscosity grades, it’s essential to understand what HPMC is. HPMC is a non-ionic, water-soluble polymer derived from cellulose, a natural polymer. It is modified through the substitution of hydroxyl (OH) groups in the cellulose structure with hydroxypropyl and methyl groups. This modification enhances water solubility and thermal stability, making HPMC suitable for a wide range of applications.

Hydroxypropyl Methylcellulose (HPMC) is a widely used cellulose ether that possesses a range of properties making it suitable for diverse applications across various industries. Among its various grades, HPMC 4000 stands out as a versatile ingredient, primarily due to its unique chemical structure and functional attributes. This article delves into what HPMC 4000 is, its properties, and its significance in multiple fields such as pharmaceuticals, food, cosmetics, and construction.

What Is HPMC Used For?

2. Wall Coatings In the production of paints and coatings, REP contributes to better adhesion and film formation. The ease of application and improved surface properties lead to a more aesthetically pleasing and durable finish.

Different Grades of HPMC

The chemical formula of hydroxyethyl cellulose can be represented as (C₂H₆O₂)n, where n refers to the degree of polymerization that varies depending on the source and processing method. The hydroxyl groups in cellulose are replaced with hydroxyethyl groups, making HEC soluble in water and providing it with certain rheological properties. The degree of substitution (DS) is a key parameter, influencing viscosity, solubility, and performance in applications.
