Viscosity Properties of Hydroxypropyl Methyl Cellulose
Hydroxypropyl methylcellulose (HPMC) is a non-ionic, water-soluble cellulose mixed ether. Appearance is white to slightly yellow powder or granular material, tasteless, odorless, non-toxic, chemically stable, and dissolves in water to form a smooth, transparent and viscous solution. One of the mo...Read more -
The synthetic method of hydroxypropyl methylcellulose
Generally, in the synthesis of hydroxypropyl methylcellulose, the refined cotton cellulose is treated with alkali solution at 35-40°C for half an hour, squeezed, the cellulose is pulverized, and appropriately aged at 35°C, so that the obtained alkali fibers are averagely polymerized degree is wit...Read more -
HPMC/HPS hot-cold gel blend
Hydroxypropyl methylcellulose (HPMC) film has excellent performance, but because HPMC is a thermal gel, the viscosity at low temperature is too low, which is not conducive to coating (or dipping) and drying at lower temperature to prepare edible film, resulting in poor processing performance; in ...Read more -
The importance of hydroxypropyl methylcellulose (HPMC) for water retention in mortar!
Why is the requirement for water retention in mortar so high, and what are the outstanding advantages of mortar with good water retention? Let me introduce to you the importance of HPMC water retention in mortar! The need for water retention Water retention of mortar refers to the ability of ...Read more -
The role of hydroxyethyl cellulose (HEC) in coatings!
Hydroxyethyl cellulose (HEC), a white or light yellow, odorless, non-toxic fibrous or powdery solid, prepared by etherification of alkaline cellulose and ethylene oxide (or chlorohydrin), belonging to the genus Nonionic soluble cellulose ethers. Because HEC has good properties of thickening, susp...Read more -
Research Progress of Cellulose based Edible Films
1. Cellulose is passed by D-glucopyranose β- A linear polymer formed by the connection of 1,4 glycoside bonds. The cellulose membrane itself is highly crystalline and cannot be gelatinized in water or formed into a membrane, so it must be chemically modified. The free hydroxyl at the positions C-...Read more -
Hydroxypropyl methylcellulose HPMC gel temperature problem
Regarding the gel temperature of hydroxypropyl methyl cellulose HPMC, many users rarely pay attention to the gel temperature of hydroxypropyl methyl cellulose. Now hydroxypropyl methyl cellulose is generally distinguished according to its viscosity, but for For some special environments and speci...Read more -
Application and preparation of hydroxyethyl methyl cellulose HEMC
