Hydroxypropyl Methylcellulose (HPMC)
Hydroxypropyl methyl cellulose is a synthetic high molecular polymer prepared by chemical modification with natural cellulose as raw material. It is a white or slightly yellow powder. Good water solubility. The hydroxypropyl methyl cellulose has properties such as thickening, adhesion, dispersion, emulsification, film formation, suspension, adsorption, gelation, protective colloid properties, surface activity and moisturizing functions.Our main HPMC products include ZK250, ZK200.
