MC, HPMC and HEMC
You May Also Be Interested In:
MC, HPMC and HEMC are non-ionic cellulose ethers produced from natural high molecular cellulose through series of chemical changes. They are characterized by the solubility in water, water retention, non-ionic type, stable PH value, surface activity, reversibility from gelling to solving at different temperature, thickening, binding, film-forming, lubricating and mold resistance. Due to all these special properties, they are widely applied for thickening, gelling, dispersing, stabilizing, water retaining and mixing improving in industries like building material, painting, synthetic resin, porcelain, medicine, food, textile, agriculture, cosmetics, cosmetics and tobacco.
