Hpmc Excipient

    This product is an industrial grade HPMC, mainly used as a dispersant in the production of polyvinyl chloride. It is the main additive for the preparation of polyvinyl chloride by suspension polymerization. In addition, it is also used as a thickener, stabilizer, emulsifier, excipient, water retaining agent, film-forming agent, etc. in the production of other petrochemical, coating, building materials, paint remover, agricultural chemicals, inks, textile printing and dyeing, ceramics, papermaking, cosmetics and other products. Its application in synthetic resins can make the resulting products have characteristics such as regular particles, looseness, suitable apparent density, and excellent processing performance, which can basically replace gelatin and polyvinyl alcohol as dispersants. In addition, in the construction process of the construction industry, it is mainly used for mechanized construction such as wall masonry, plastering, and joint filling; Especially in decorative construction, it is used to paste tiles, marble, plastic decorations, etc., with high bonding strength and can also reduce the amount of cement used. Used as a thickener in the paint industry, it makes the coating bright and delicate, does not shed powder, and improves leveling properties.

Appearance: White or off-white powder or granules.
Solubility: It can quickly disperse and swell in cold water to form a clear or slightly turbid colloidal solution.
Thermal gelation: The aqueous solution will form a gel after heating, and can be dissolved again after cooling.
Thickening: It can significantly increase the viscosity of the liquid.
Adhesion: It can be used as an adhesive to enhance the bonding strength between materials.
Emulsification: It can be used as an emulsifier to stabilize the emulsion system.
Film-forming: It can form a film with good toughness and transparency.





Water retention: It can effectively retain moisture and prevent materials from drying out too quickly.
Surface activity: It has surface activity and can reduce surface tension.
Enzyme resistance: Not easily degraded by enzymes.

Not sensitive to pH value: Within the pH range of 2-12, the solubility of HPMC in water is not affected.

Compatibility with other additives: Can be used in combination with multiple additives.
