China Ordinary Hydroxypropyl Methyl Cellulose​

China Ordinary Hydroxypropyl Methyl Cellulose (HPMC)

Hydroxypropyl Methyl Cellulose (HPMC) is a semi-synthetic polymer derived from cellulose, widely used across multiple industries. Ordinary HPMC refers to the standard-grade variant that requires thermal dispersion for complete dissolution, distinguishing it from instant-dissolving types.

As the world's largest HPMC producer, China supplies over 60% of global demand, with ordinary HPMC remaining a staple product for its cost-effectiveness and reliable performance.

Key Characteristics of Ordinary HPMC

1. Thermal Dispersion Requirement

• Requires initial mixing in hot water (typically 60-80°C) before cold water addition

• Forms smooth solutions without clumping when properly dispersed

2. Viscosity Stability

• Maintains consistent viscosity across pH ranges (2-11)

• Provides reliable thickening performance in final applications

3. Film-Forming Properties

• Creates uniform, flexible films upon drying

• Offers excellent oxygen barrier characteristics

4. Temperature Tolerance

• Exhibits reversible thermal gelation behavior

• Maintains functionality across wide temperature ranges
