Sodium carboxymethyl cellulose (CMC)
Product performance and characteristics
CMC is a kind of high purity and refined cellulose ether prepared from natural cellulose. The appearance of the product is white powder. After dissolution, it has high light transmittance, better rheological property and thixotropic property. High degree of substitution, acid and salt resistance.
