1、 product characteristic
CMC is widely used in different industrial areas as additive, cementing agent of tobacco industry, sizing agent and the addition agent for printing and dyeing of textile. Used in the mosquito-repellent incense, CMC has the good compatibility and it can mainly strengthen toughness, make the final product easy to be molding, enhance the degree of finish of surface and edge. Moreover, CMC can prevent dirt from re-depositing while being used both in dry powder detergent and liquid detergent; Meanwhile CMC mainly plays a role on stability and thickening in liquid detergent. In addition, CMC is used as adhesive, disintegrating and dispersing agent, humectants, suspending agent, stabilizer and so on in the pharmaceutical industry. |
