Introduction of Hydroxypropyl methyl cellulose HPMC

1. Overview Hydroxypropyl Methyl Cellulose (HPMC) is a non-ionic cellulose ether made from natural polymer material – cellulose through a series of chemical processes. Hydroxypropyl methylcellulose (HPMC) is an odorless, tasteless, non-toxic self-coloring powder, which can be dissolved in c... Read More

What is Characteristics of HPMC in dry-mixed mortar

1. The characteristics of HPMC in ordinary mortar HPMC is mainly used as retarder and water retention agent in cement proportioning. In concrete components and mortar, it can improve viscosity and shrinkage rate, strengthen cohesive force, control cement setting time, and improve initial strength... Read More

What is Starch Ether?

Starch ether is mainly used in construction mortar, which can affect the consistency of mortar based on gypsum, cement and lime, and change the construction and sag resistance of mortar. Starch ethers are usually used in conjunction with non-modified and modified cellulose ethers. It is suitable ... Read More

What are Hydroxyethyl cellulose uses?

Hydroxyethyl cellulose (HEC) is a non-ionic cellulose ether made from natural polymer material cellulose through a series of etherification. It is an odorless, tasteless, non-toxic white powder or granule, which can be dissolved in cold water to form a transparent viscous solution, and the dissol... Read More

How do you make methylcellulose?

Firstly, the cellulose raw material wood pulp/refined cotton is crushed, then alkalized and pulped under the action of caustic soda. Add olefin oxide (such as ethylene oxide or propylene oxide) and methyl chloride for etherification. Finally, water washing and purification are carried out to fina... Read More
