Hydroxyethyl Cellulose (HEC) A Versatile Polymer in Modern Industries

Spray drying: The polymer dispersion is fed into a spray dryer where it is atomized into fine droplets. Hot air is then used to dry these droplets, forming small polymer particles.

HPMC is derived from cellulose, a natural polymer found in plant cell walls. The manufacturing process begins with the extraction of cellulose, which is then chemically modified through hydroxypropyl and methyl substitution. This process not only enhances the solubility and thermal stability of cellulose but also expands its applications. HPMC is widely used as a thickening agent, film former, and emulsifier, making it invaluable in the production of paints, coatings, pharmaceuticals, food products, and personal care items.
