HEMC is better than HPMC?

By |2023-01-30T09:20:19+00:00January 4th, 2023|Industry knowledge|

HPMC and HEMC have similar roles in building materials. It can be used as dispersant, water retaining agent, thickener and binder, etc. It is mainly used in the molding of cement mortar and gypsum products. Used in cement mortar to increase its cohesiveness, workability, reduce flocculation, improve viscosity and shrinkage, and have water retention, reduce

HPMC is a variety of natural plant cellulose, and it is also an excellent pharmaceutical excipient, which has a wide range of sources. At present, it is widely used at home and abroad, and it is one of the pharmaceutical excipients with the highest utilization rate in oral drugs. HPMC plays a vital role in

Factors Affecting the Viscosity of Hydroxypropyl Methyl Cellulose

By |2022-12-05T08:45:12+00:00December 5th, 2022|Industry knowledge|

Hydroxypropylmethylcellulose (HPMC) is a nonionic water-soluble mixed ether of cellulose. Appearance is white to light yellow powder or granules, tasteless, odorless, non-toxic, chemically stable product, soluble in water to form a smooth and transparent viscous solution. 1. The relationship between viscosity and concentration The viscosity of hydroxypropyl methylcellulose increases with the concentration of the product

The characteristics of daily chemical grade cellulose ether

By |2022-12-02T07:04:18+00:00December 2nd, 2022|Product Applications|

Daily chemical grade hypromellose is a synthetic polymer made from refined cotton through chemical modification. Cellulose ether is a derivative of natural cellulose. The production of cellulose ether is different from synthetic polymers. Its basic material is cellulose, a natural polymer compound. Due to the particularity of the natural cellulose structure, the cellulose itself has

Properties of Hydroxypropyl Methyl Cellulose

By |2022-11-29T06:47:21+00:00November 29th, 2022|Product Applications|

Hydroxypropyl methylcellulose(HPMC) is easily soluble in cold water, but it will encounter difficulty in dissolving in hot water. But its gelation temperature in hot water is significantly higher than that of methyl cellulose. The solubility in cold water is also greatly improved compared with methyl cellulose. Hydroxypropyl methylcellulose(HPMC) is stable to acid and alkali, and

HPMC for construction additives

The higher the viscosity, the more obvious the thickening effect of the mortar, but it is not proportional. The higher the viscosity, the more sticky the wet mortar will be. During construction, it will stick to the scraper and have high adhesion to the substrate. But it does little to increase the structural strength of
