Application of hydroxypropyl methylcellulose(HPMC)

The application of synthetic resin can make the obtained products have particle neat, loose, appropriate specific gravity and excellent processing performance.

Thus basically replacing gelatin and polyvinyl alcohol as dispersant.

In addition, propylene methyl cellulose in the process of construction industry, mainly used for wall, plaster whitewash, embedded seam and other mechanized construction;.

With dry coating industry as a thickening agent, can make the coating bright and fine, do not remove powder, improve the piping performance.

This pharmaceutical grade is a multi-purpose pharmaceutical excipients.

Can be used as thickener, dispersant, emulsifier, and film forming agent.

An adhesive in the tablets.

Can significantly improve the dissolution of drugs, and can be used as a film coating material, can enhance the waterproof of the tablet, can also be used in food.

Acylmethyl cellulose alias hydroxypropyl methyl cellulose.

Cellulose hydroxypropyl methyl ether: Hypromellose, Cellulose.

This product uses highly pure cotton cellulose as raw material, under alkaline conditions by special etherification.

The whole process is completed under automatic monitoring, without any animal organs and oils and other active ingredients.

This product is non-ionic cellulose ether, appearance white powder, tasteless.

Acryl methylcellulose is soluble in water and most polar organic solvents and an appropriate proportion of ethanol / water, propane alcohol / water, dichloroethane, etc., insoluble in ether, acetone, absolute ethanol, and expanded into a clarified or slightly turbid colloidal solution in cold water.

Aqueous solution has surface activity, high transparency and stable performance.HPMC has hot gel properties.

The product aqueous solution forms a gel precipitation after heating, and dissolves after cooling.

The product gel temperature of different specifications is different.

The solubility varies with the viscosity.

100 order pass rate is greater than 100%.Heack density: 0.25-0.70g (usually about 0.4g), 1.26-1.31.

Discolor temperature: 180-200℃, carbonization temperature: 280-300℃.
