Products Description
This product is industrial grade HPMC, mainly used as a dispersant in the production of polyvinyl chloride, and is the main auxiliary agent for the preparation of PVC by suspension polymerization. In addition, it is used as a thickener, stabilizer, emulsifier, excipient, water-retaining agent, film-forming agent, etc. in the production of other products such as petrochemicals, coatings, building materials, paint removers, agricultural chemicals, inks, textile printing and dyeing, ceramics, papermaking, and cosmetics. In the application of synthetic resins, the obtained products can have the characteristics of regular particles, looseness, appropriate apparent specific gravity, and excellent processing performance, thus basically replacing gelatin and polyvinyl alcohol as dispersants. In addition, in the construction process of the building industry, it is mainly used in mechanized construction such as wall building, plastering, and caulking; especially in decorative construction, it is used to paste tiles, marble, and plastic decorations, with high bonding strength, and can also reduce the amount of cement. It is used as a thickener in the coating industry to make the layer bright and delicate, without powder shedding, and improve leveling performance.
Physical properties
Appearance: White or off-white powder, odorless.
- Solubility:
- Soluble in cold water, insoluble in hot water (gelling at high temperature).
- Insoluble in organic solvents (such as ethanol, acetone).
- Viscosity range: Wide range (5~200,000 mPa·s, depending on model and concentration).
- pH stability: Stable in the pH range of 2~12.

Uses
This product is used as a thickener, dispersant, adhesive, excipient, oil-resistant coating, filler, emulsifier and stabilizer in the textile industry. It is also widely used in synthetic resins, petrochemicals, ceramics, papermaking, leather, medicine, food and cosmetics.
Main functions
- Thickener: Increase solution viscosity, used in coatings, adhesives, etc.
- Water-retaining agent: Delay water evaporation in building materials (such as cement mortar).
- Adhesive: Forming of pharmaceutical tablets and foods.
- Emulsifier stabilizer: Prevent emulsion stratification.
- Sustained-release agent: Control drug release rate (pharmaceutical field).
Model classification
HPMC models are usually distinguished by viscosity (such as HPMC E5, E15, K4M, etc.), and different suffixes indicate:
- E series: high degree of substitution, suitable for building materials.
- K series: low degree of substitution, suitable for sustained release of medicines.
- F series: food grade.
