As an additive for cement mortar, the cellulose ether usually has an addition amount not more than 2% of cement mass. For the study on cellulose ether, there has been a long history of research abroad. For example, DOW had successfully developed and marketed as early as 1938. First, the higher viscosity the cellulose ether.. read more →

In the pharmaceutical industry, hydroxy propyl methyl cellulose (HPMC) can act as pharmaceutical excipients. It is widely used in oral drugs such as matrix controlled-release and sustained-release preparations as the release-blocking material to regulate the drug release, or as sustained-release agents, pellets and capsules of coating materials. The most widely used are dimethyl carboxymethyl cellulose.. read more →

In the formulations of building materials, the dosage of cellulose ether is only 0.1% to 1%. But it plays an irreplaceable role. Various applications of cellulose ether in building materials will be introduced as follows. 1. Latex and Latex Building Materials Such cellulose derivatives as MC, CMC, HEC and HPMC can be used in the.. read more →

The water retention property of HPMC is also related to the temperature used, and will decrease with increasing temperature. But in the actual material application, in many circumstances, the dry mortar is often used in construction under the conditions of high temperature (above 40 degrees). In the case of plastering for exterior wall putty under.. read more →

1. CMC and HPMC added to the mortar can play the dual role of water retention and thickening. With the increase of dosage, the layering degree of mortar will decrease. CMC is an ionic cellulose ether, and can react with Ca(OH)2 when added to the mortar. CMC has no obvious improvement in the water retention.. read more →

In the food industry, as a natural food additive, Sodium CarboxyMethyl Cellulose is non-toxic, safe and reliable, with no side effects and excellent performance, and its application is not limited. In food applications, Sodium CarboxyMethyl Cellulose is not only an excellent emulsion stabilizer and thickener, but also has excellent freezing as well as melting stability,.. read more →

As a pharmaceutical excipient, HPMC has great application value, and it has the advantages that other excipients do not have, so has been widely used in recent years, especially in the pharmaceutical industry. It has great superiority as an excipient. Research and development of it is of great significance to make it applied in wider.. read more →

Difference between Methyl Cellulose (MC) and Hydroxypropyl Methyl Cellulose (HPMC) 1. Hydroxypropyl Methyl Cellulose is easily soluble in cold water but difficult to be soluble in hot water. However, its gelling temperature in hot water is significantly higher than that of methyl cellulose (MC). And compared with Methyl Cellulose, the dissolution in cold water has.. read more →

Rheological Property of Methyl cellulose Solution   The rheological property of Methyl cellulose plays a very important role in many practical applications.  In coatings, cosmetics, food industry and building material products, it is bound to affect their flow behavior.   The viscosity of Newtonian fluid is not dependent on the shear rate (or the gradient.. read more →

Properties of Methyl Cellulose   Methyl cellulose have excellent water retention properties, and are widely used in the curing of cement and plaster, and some water-based paints and wallpaper adhesives with certain requirements for adhesion. The water retention capacity of methyl cellulose will increase with the increase of the hydrophilic group content and viscosity.  .. read more →
