Product Description
Hydroxypropyl Methyl Cellulose
CAS: 9004-65-3
.Physical and Chemical properties:
1. Appearance: white or off-white powder, tasteless and tasteless
2. Granularity: ≧98.5% (100 M) ;100% (80 M).
3. Carbonization Temperature: 280-300℃.
4. Apparent Density: 0.25-0.70g/ (0.5g more or less), Specific gravity 1.26-1.31.
5. Discoloration Temperature: 190-200℃.
6. Surface tension: 42-56dyn/cm (20% aqueous solution).
7.Solubility:soluble in water and some organic solvents, in a certain proportion, such as ethanol/water, propanol/water,
dichloroethane, etc. The aqueous solution has surface activity, high transparency and stable performance. The products with different specifications have different gel temperatures, which is the thermal gel properties of HPMC. The solubility changes with the viscosity. The lower the viscosity, the greater the solubility. HPMC with different specifications have differentperformances. The dissolution of HPMC in water is not affected by pH
8. As the methoxy content decreases, the gel point will increase, the water solubility will decrease, and the surface activity
will decrease.
9. HPMC also has the characteristics of thickening ability, salt discharge, low ash content, pH stability, water retention,
dimensional stability, excellent film-forming properties, and extensive enzyme resistance, dispersibility and adhesion.

Application：
As a dispersant in the production of polyvinyl chloride, and is the main auxiliary agent for the preparation of PVC by suspensionpolymerization.
In addition, it is used as thickener, stabilizer, emulsifier, excipient, water retaining agent, film forming in the production of other petrochemicals, building materials, paint removers, agricultural chemicals, inks, textile printing and dyeing, ceramics, papermaking, cosmetics and other products, etc.
In synthetic resins，it can make the obtained products with the characteristics of regular particles, looseness, suitable apparentspecific gravity, and excellent processing performance, which basically replaces gelatin and polyvinyl alcohol as dispersants.
In building industry, it is mainly used for mechanized construction such as wall masonry, plastering, and caulking;
In special decorative construction, it is used for pasting tiles, marbles, and plastic decorations, which has high bonding
strength and can reduce the amount of cement.
As a thickener in the coating industry, it can make the coating bright and delicate, without powdering, and improve the leveling performance.
In plastering plaster, pasting plaster, caulking plaster, water-resistant putty, it can significantly increase its water retention and adhesive strength.
It can also be used in functional ceramics, metallurgy, seed coating agents, water-based inks, cosmetics, electronics, printing and dyeing, papermaking and other fields
