HPMC Hydroxypropyl Methyl Cellulose - High-Quality Suppliers and Factory in China for Colloidal Solutions
Product Overview
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.

Frequently Asked Questions
What is HPMC and what is it made from?
HPMC (Hydroxypropyl Methylcellulose) is a semi-synthetic, non-ionic cellulose mixed ether. It is prepared through the chemical modification of natural cellulose, typically using cotton or wood as raw materials via alkalization and etherification processes.
What are the primary characteristics of HPMC?
HPMC features excellent thickening properties, outstanding film formation, good biocompatibility (non-toxic and tasteless), and environmental degradability. It also dissolves quickly in cold water to form a transparent, viscous solution.
In which industries is HPMC commonly used?
HPMC is widely used in the construction industry (as a water retaining and retarding agent), the coating industry (as a thickener and stabilizer), the pharmaceutical field (for capsule shells and sustained-release agents), and the food industry (as an emulsifier and thickener).
How should HPMC be dissolved and stored?
It is important to select the appropriate dissolution method according to the specific model of HPMC. For storage, it must be placed in a dry, clean, and cool environment to ensure its quality and performance are maintained.
What are the market prospects for HPMC?
Driven by global economic growth and increasing environmental awareness, the demand for HPMC continues to rise.
