Hydroxypropyl Methyl Cellulose (HPMC) is non-ionic cellulose ether, made by natural high polymer cellulose as raw material and series of chemical processing. They provide water retention and cohesiveness to mixtures. With special modification, it can be used to control thickening, water demand, workability, sag resistance, strength and other important properties of the final product.
It is widely used as thickener, adhesive, water preserving agent, film-foaming agent in building materials, industrial coatings, synthetic resin, ceramic industry, medicine, food, textile, agricultural, cosmetic and other industries.
