Product Description

 

Product Description

Hydroxypropyl methyl cellulose (HPMC) or hypromellose, HPMC is odorless, tasteless,non-toxic cellulose ethers producted from natural hIgh molecular cellulose through series of chemical processing and achieved.

As a film forming polymer our product Hydroxypropyl Methyl Cellulose(HPMC) is the ideal material for empty capsule shell. Empty capsule shelL produce by our HPMC has the properties of low moisture content, superior stabilities, high filling rate.

Product Properties

1 . Resistance to salting : Hydroxypropyl methyl cellulose (HPMC) is a nonionic cellulose ether and it is not a polyelectrolyte . The aqueous solution of Hydroxypropyl methyl cellulose (HPMC) is comparatively stable even in the presence of metal salts or organic electrolytes . However, when the concentration of electrolytes exceeds a certain limit, gelation and precipitation may result .

2 . Surface activity : An aqueous solution of Hydroxypropyl methyl cellulose (HPMC) has a high surface activity and functions as a protective colloid agent , emulsion stabilizer and dispersant .

3 . Thermal gelation :An aqueous solution of Hydroxypropyl methyl cellulose (HPMC) will gel or precipitate when heated to a certain temperature , but it reverts to the original solution state on subsequent cooling . The temperature at which gelation or precipitation occur depends on the type of HPMC , its concentration and the rate of heating .

4 . pH stability :The viscosity of an aqueous solution of HPMC is hardly affected by acid or alkali , and the product can develop an original viscosity in the range of 3 . 0~11 . 0 . Therefore , the solution viscosity tends to keep stable during prolonged storage .

5. Water retention :Hydroxypropyl methyl cellulose (HPMC) is a high effective water retention agent . Its pharmaceutical grade product can be widely used in food, cosmetics and many other fields .

6 . Film forming :Hydroxypropyl methyl cellulose (HPMC) provides a strong , flexible and transparent film having a good barrier property against oil and grease .In food application , this property is often utilized for water retention and oil adsorption .

7 . Cohesiveness (Binding property) : Hydroxypropyl methyl cellulose (HPMC) , as a high performance binder, can also be used for molding food and medicine .
