Hydroxypropyl Methylcellulose HPMC/HEC/MHPC

Short Description:

Hydroxypropyl methylcellulose, also known as hypromellose, is one of the non-ionic cellulose mixed ethers.It is a semi-synthetic, inactive, viscoelastic polymer, often used as a lubricant in ophthalmology, or as an excipient or excipient in oral medicine.
It is soluble in water and some solvents, such as ethanol/water, propanol/water in appropriate proportions. The aqueous solution has surface activity. High transparency and stable performance. Different specifications of products have different gel temperatures and solubility changes with viscosity. The lower the viscosity, the greater the solubility. Different specifications of HPMC have different performances. The dissolution of HPMC in water is not affected by pH.

    Hydroxypropyl Methylcellulose Function:

    1. Construction industry: As a water-retaining agent and retarder of cement mortar, it makes the mortar pumpable. Used as a binder in plaster, plaster, putty powder or other building materials to improve spreadability and prolong operation time. It can be used to paste ceramic tiles, marble, plastic decoration, paste enhancer, and can also reduce the amount of cement. The water retention properties of HPMC prevent the slurry from cracking due to drying too fast after application, and enhance the strength after hardening.
    2. Ceramic manufacturing industry: widely used as a binder in the manufacturing of ceramic products.
    3. Coating industry: As a thickener, dispersant and stabilizer in the coating industry, it has good compatibility in water or organic solvents. As a paint remover.
    4. Ink printing: As a thickener, dispersant and stabilizer in the ink industry, it has good compatibility in water or organic solvents.
    5. Plastics: used as mold release agents, softeners, lubricants, etc.
    6. Polyvinyl chloride: It is used as a dispersant in the production of polyvinyl chloride and is the main auxiliary agent for the preparation of PVC by suspension polymerization.
    7. Pharmaceutical industry: coating materials; film materials; rate-controlling polymer materials for sustained-release preparations; stabilizers; suspending agents; tablet binders; viscosity-increasing agents
    8. Others: It is also widely used in leather, paper product industry, fruit and vegetable preservation and textile industry.

    Hydroxypropyl methylcellulose Dissolution Method:

    1. All models can be added to the material by dry mixing.
    2. When it needs to be added directly to the aqueous solution at room temperature, it is best to use the cold water dispersion type, and it usually takes 10-90 minutes to thicken after adding.
    3. For ordinary models, first stir and disperse with hot water, and then add cold water to stir and cool to dissolve.
    4. If agglomeration and wrapping occurs during dissolution, it is due to insufficient stirring or the normal type is directly added to cold water. At this time, it should be stirred quickly.
    5. If bubbles are generated during dissolution, they can be allowed to stand for 2-12 hours (the specific time is determined by the consistency of the solution) or be removed by vacuum, pressurization, etc., or an appropriate amount of defoamer can be added.
