Low viscosity Hydroxypropyl Methylcellulose
Hydroxypropyl methylcellulose (HPMC) is a nonionic cellulose ether polymer. Depending on the degree of substitution of the substituent groups and the degree of modification, they exhibit different chemical properties. It is a nonionic white cellulose ether powder.
Key Features and Performance
Low-viscosity grade HPMC maintains basic properties such as film-forming ability, water retention, and stability while offering lower solution viscosity and excellent flowability. It is particularly suitable for applications requiring high solid content, high flowability, or special rheological properties.
- Excellent flowability: Suitable for self-leveling, spraying, and other application methods
- High transparency: Clear solution with uniform dispersionfont
- Excellent film-forming performance: Enhances the density and durability of the finished product
- Easy to mix: Good compatibility with other components
- Low foaming: Reduces bubble defects
Field of application
Low-viscosity hydroxypropyl methylcellulose is suitable for industrial and pharmaceutical applications that require high fluidity, permeability, and rapid dissolution.
- Ready-to-use dry-mixed mortar
Simply add water and stir to achieve rapid and uniform dissolution, reducing waiting time.
- Chemical formulation production
Used in water-based systems requiring immediate dissolution, such as water-based coatings and adhesives.
- Cosmetic cold mixing process
Forms a uniform system quickly without heating during production, reducing energy consumption.
- Pharmaceutical and food industry
Used as an instant thickener or colloidal stabilizer.
- Water treatment agents
Disperses quickly to achieve uniform mixing.
