Technical Details & Test Data
- HPMC
HPMC - Hydroxypropyl methylcellulose is a cellulose ether produced in our state of the art factory located in Zacapu Mexico.
Cellulose is a substantial structural component of the cell wall of plants and can be considered as one of the most important biopolymers in nature. It is insoluble in water. By modifying the cellulose, water-soluble derivatives are achieved. Besides methylcellulose and others, HPMC is one of most commonly used derivatives for many different applications.
Properties
HPMC forms clear solutions in water. In comparison to other hydrocolloids, aqueous solutions of HPMC become a gel when heated to temperatures specific for each grade.
The reversibility of the thermal gelation is a special property of HPMC.
Gelation points are depending on different factors such as e.g. degree of substitution which is adjusted by our modern production technology.
Another key property of HPMC is the ability to form transparent films. In other applications, HPMC can also be used to achieve stickiness.
HPMC is compatible with other natural and synthetic polymers such as e.g. starch, xanthan, casein, polyvinyl alcohol, cellulose- and guar ethers , and is also tolerant towards salts even in higher concentrations.
The functionalities of HPMC are accessible among a very broad pH range.
