Application:
CMC is a kind of linear high polymer ionic substances, refinement for fibrous white or light yellow powder, non-toxic, tasteless, soluble in hot and cold water become transparent viscous solution, has the general natural rubber and synthetic rubber do not have many advantages, is widely used in food processing, beverage, textile, papermaking, oil drilling, daily chemical, paint, tobacco, building materials, ceramics, mosquito-repellent incense, detergent and other industries, has a unique thickening agent, emulsifier, water retention agent, binder, dispersion, suspending agent, bulking fixing agent, retarder in various sectors play their part, commonly known as "industrial monosodium glutamate."
