DESCRIPTION:
HPMC is a semi-synthetic nonionic cellulose mixed ether that usually appears as a white or white-like powder. It is prepared by chemical modification of natural cellulose.
Good water solubility: It can be quickly dissolved in cold water to form a transparent viscous solution.
PRODUCT CHARACTERISTICS
Excellent thickening: Significantly improve the viscosity and consistency of the liquid, improve fluidity and stability.
Excellent film formation: When dried, a tough film is formed, which is water resistant, breathable and flexible.
Good biocompatibility: Non-toxic, tasteless, non-irritating, suitable for biomedicine field.
Environmentally degradable: Naturally degradable in the environment, in line with the requirements of green environmental protection.
PRODUCT USE
Construction industry: Used as water retaining agent and retarding agent of cement mortar to improve spreadability and operation time; As an adhesive, it is used to paste decorative materials such as tiles and marbles.
Coating industry: As a thickener, dispersant and stabilizer, improve the performance of coatings.
Pharmaceutical field: It can be used as film coating material, sustained release agent, capsule shell material, suspension aid, etc.
Food industry: Acting as thickener, emulsifier, stabilizer and other roles.
