    MODCELL®  HPMC is made by propylene oxide, methyl choride with alkali-cellulose  after a chemical process called etherification under rigidly controlled conditions. The resultant nonionic polymer is purified, dried and ground to a fine white powder, this water-insoluble cellulose is turned into water-soluble nonionic polymer. Hydroxypropyl methyl cellulose is a good film-former and varies somewhat in physical and chemical properties. HPMC is quite hydrophilic and readily soluble in cold water.

    Longou company is leading HPMC factory in China for 14 years. Our technical engineer team also develop modified products according to different applications to better improve the workability. Communicate with us to find out a suitable product for yout projects.

    Cellulose Ether Hydroxyethyl methyl cellulose HEMC LE40M for Gypsum Drymix Mortar

    Hydroxyethyl methyl cellulose HEMC is made from highly pure cotton cellulose. After alkali treatment and special etherification becomes HEMC. It does not contain any animal fats and other active ingredients.

    Hydroxyethyl methyl cellulose HEMC LE40M is multifunctional additive for ready-mix and dry-mix products. It is a high quality thickening agent and water retention agent, widely used in gypsum based products. 

  • Hydroxyethyl methyl cellulose LE6M CAS 9032-42-2 for ready mix mortar with high water retention

    Hydroxyethyl methyl cellulose LE6M CAS 9032-42-2 for ready mix mortar with high water retention

    Hydroxyethyl methyl cellulose CAS 9032-42-2, also known as hypromellose, cellulose hydroxypropyl methyl ether, is obtained by using high purity cotton cellulose as a raw material and special etherification under alkaline conditions.

    Hydroxyethyl methyl cellulose HEMC is widely used as a thickener, stabilizer and water retaining agent for building materials. It provides water retention and workability for mortars, it can improve adhesion, reduce skinning and increase open time. HEMC also has thickening ability, low ash content, PH stability, water retention, excellent film forming, and extensive enzyme resistance, dispersion and so on.

    Longou company is the main cellulose ether factory in China. It provides various grades of common cellulose ether and some modified cellulose ether specially for tile adhesive, wall putty, renders and etc.

    Cellulose ethers are a major class of commercially important water-soluble polymers for the construction and building industries. Cellulose ethers are capable of increasing the viscosity of aqueous media. The viscosifying ability of a cellulose ether is primarily controlled by its molecular weight, chemical substituents attached to it, and conformational characteristics of the polymer chain.

    Methylhydroxyethyl cellulose (MHEC), methylhydroxypropyl cellulose (MHPC), hydroxyethyl cellulose (HEC), modified cellulose ethers either alone or in combination are among the most widely used cellulose ethers in mortar formulations.

    Hydroxypropyl cellulose HPMC cellulose ether 100000 mpa.s HS CODE 3912390000

    Cellulose ether HPMC is short for hydroxypropyl cellulose. It is also called hypromellose,or hydroxypropyl cellulose. 

    Material: High purlty Refined cotton

    HPMC is a type of non-ionic cellulose ether, white powder appearance, odorless and tasteless, soluble in water and most polar organic solvents. Its water solution has a surface activity, high transparency, stable performance. HPMC has a thermal gel properties, after heating, the product solution formed the gel precipitation, dissolving after cooling. Different specifications products have different gel temperature. Solubility changes with viscosity’s difference. The lower viscosity, the higher solubility, different specifications HPMC have difference in properties, dissolving HPMC in water won’t be affected by PH value.

    Granularity: 100mesh, over 99% passing rate, Bulk Density: 0.25-0.70g(usu. 0.5g or so), Proportion: 1.26-1.31, Color Temperature: 190-200℃

    Carbonization Temperature: 280-300℃,Surface Tension: 42-56dyn/cm
    With the increase of Methoxyl, HPMC’s gel point decreases, the rise of water solubility and surface activity. HPMC has the features of thickening, salt removing, low ash content, fine film-forming properties. and wide range of anti-ether, dispersion, and adhesion properties.
