HPMC Hydroxypropyl Methyl Cellulose

HPMC is odorless, tasteless and non-toxic. HPMC (hydroxypropyl methylcellulose) is a multifunctional polymer material, usually white or slightly yellow powder, with good water solubility, thickening, water retention and film-forming properties. When HPMC is mixed with water, it can quickly dissolve and form a transparent or translucent viscous liquid, showing good solubility and rheology.It is widely used in the construction, medicine, food and daily chemical industries as a thickener, stabilizer, excipient, etc. to improve product performance and quality.

As a multifunctional polymer material, the market demand for HPMC is growing steadily. This is mainly due to cellulose function in many key fields, such as tile adhesives, putty powder and coatings in the construction industry, tablets and capsules in the pharmaceutical industry, and flour products and ice cream in the food industry. At the same time, HPMC’s environmental performance and sustainable development also make it a popular choice in the future market. Through continuous research and development and improvement of production processes, we can provide you with higher quality and more competitive powder cellulose products.

As one of the professional cellulose manufacturers,we select refined cotton as the cellulose substrate, and prepare auxiliary materials such as sodium hydroxide, propylene oxide, and methyl chloride. Refine cotton reacts with sodium hydroxide to generate alkali cellulose in preparation for the etherification reaction. Under controlled conditions, alkali cellulose reacts with etherifying agents (methyl chloride, propylene oxide) to introduce hydroxypropyl and methyl groups to form HPMC. The reaction product is washed to remove impurities and then dried to obtain HPMC powder. The dried HPMC is ground and sieved to ensure uniform particle size. The cellulose powder is packaged and strictly controlled to ensure that the product meets the standards.

HPMC should be stored in a dry environment to avoid moisture. Be sure to stir thoroughly before use to ensure uniformity. When using HPMC, it is necessary to accurately mix according to application requirements to ensure the effect; avoid high temperatures during processing to protect performance. At the same time, comply with safety regulations and wear protective equipment.
