HPMC Hydroxypropyl Methyl Cellulose

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.

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.

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.

Usually cotton, wood as raw materials, through the alkalization, propylene oxide and chloromethane etherification process to prepare.

With global economic development and environmental awareness, its market demand continues to grow. Applications in green buildings, environmental protection coatings, biomedicine and other fields continue to expand, and the market scale is expected to further expand. But at the same time, the industry is also facing challenges in technological innovation, market competition and environmental protection requirements.

In the process of use, it is necessary to pay attention to the dissolution method, and choose the appropriate dissolution method according to different models. At the same time, pay attention to storage conditions, should be placed in a dry, clean cool place to ensure product quality and performance.
