2. Construction Industry In construction, HPMC is used as an additive in mortars, tile adhesives, and other building materials. Its water retention properties significantly enhance workability and enhance the durability of construction materials, making it an essential component as urbanization continues globally.
- 2. Construction Industry
The production of HPMC is characterized by controlling the degree of substitution and the molecular weight. The degree of substitution refers to how many of the hydroxyl groups in the cellulose molecule have been replaced by methyl and hydroxypropyl groups. This parameter influences the water solubility and viscosity of HPMC. For instance, HPMC with a higher degree of substitution and molecular weight tends to have better thickening properties and higher gel strength, making it appealing for various applications.
what is hpmc made fromIn TRS 996-JECFA 74/51, WHO evaluate is as followings:
To synthesize hydroxyethyl cellulose, cellulose is first extracted from plant sources such as wood pulp, cotton, or other fibrous materials. The cellulose is then treated with an alkali solution to remove impurities and increase its reactivity. Next, the cellulose is reacted with ethylene oxide in the presence of a catalyst under controlled conditions to introduce hydroxyethyl groups onto the cellulose backbone.
2. Viscosity The viscosity of HPMC can significantly affect its performance in formulations. Higher viscosity grades are suitable for applications requiring thicker consistency, while lower viscosity grades are ideal for liquid formulations. Buyers should assess the viscosity requirement based on their specific needs.
HPMC is synthesized through the reaction of cellulose with propylene oxide and methyl chloride. The numbers in its name, such as 4000, indicate the viscosity grade—specifically, the viscosity of a 2% aqueous solution at 20°C, which for HPMC 4000 is approximately 4000 mPa·s. This viscosity allows HPMC 4000 to function effectively as a thickener, gelling agent, and suspension agent.
