Types of HPMC
HPMC can be categorized based on its surface treatment and viscosity. The following table outlines the different types of HPMC available in the market:
| Type | Surface Treatment | Viscosity Range (mPa.s) | Applications |
|---|---|---|---|
| Surface-Treated HPMC | Modified for rapid dispersion in cold water | 300 – 100,000 | Liquid systems, personal care products, paints |
| Non-Surface Treated HPMC | Disperses quickly in hot water | 400 – 75,000 | Dry mix applications, mortars, tile adhesives |
Surface-Treated HPMC
Surface-treated HPMC is designed for applications requiring quick dispersion in cold water. It is ideal for liquid formulations, such as hand soaps and detergents. This type of HPMC ensures a smooth mixing process and enhances the overall performance of the final product.
Non-Surface Treated HPMC
Non-surface treated HPMC is primarily used in dry mix applications. It disperses rapidly in hot water, making it suitable for products like wall putty, tile adhesive, and self-leveling compounds. This type of HPMC is known for its excellent water retention and thickening properties.
Applications of HPMC
HPMC is utilized in various industries, including construction, personal care, and food. Here are some notable applications:
-
