Hydroxyethyl methyl cellulose (HEMC) is a non-ionic cellulose ether made from natural polymer material cellulose after a series of etherification. It is an odorless, tasteless, non-toxic white powder Or particles, soluble in cold and hot water to form a transparent viscous solution, insoluble in general organic solvents, and the dissolution is not affected by the pH value. It has the characteristics of thickening, bonding, dispersion, emulsification, film formation, suspension, adsorption, surface activity, moisture retention and salt resistance.
It can be packed in paper-plastic composite bag lined with polyethylene plastic bag, cardboard drum or plastic coated, etc. The net weight of each piece is 25KG. During storage and transportation, it should be protected from sun and rain, fire and moisture.
