Common questions about cellulose products and their applications Part I: Basic problems of cellulose ether
Common questions about cellulose products and their applications Part I: Basic problems of cellulos ether 1. Mechanism of thickening and swelling The mechanism of thickening and swelling of hydroxyethyl cellulose 250HHR PC has two main points: − The hydroxyl group of hydroxyethyl cellulose forms a hydrogen bond network structure with water molecules − entanglement between […]
what is Hypromellose, hydroxypropyl methylcellulose (HPMC)?
What is it: HPMC is a chemically modified cellulose polymer that is off-white in color and considered safe for human consumption. It is most commonly used as an alternative to gelatin and gluten in vegan-friendly products. Common uses: Alternative to Gelatin: It serves as an alternative to gelatin because of its vegetarian source and its physical […]
Basic concepts of cellulose ether–MHEC and MHPC
In dry mortar, the addition of cellulose ether is very low, but it can significantly improve the performance of wet mortar, which is a major additive that affects the performance of mortar construction. The cellulose ether is mainly made of natural fiber, and is processed by alkali dissolution, graft reaction(etherification), water washing, drying, grinding and […]
