Hydroxy propyl methyl cellulose (HPMC) is a white to off-white fibrous powder or granule, soluble in water and some organic solvents, but insoluble in ethanol. Its CAS NO. is: 9004-65-3.
Applications:
1. Construction industry: The water-retaining properties of HPMC prevent the slurry from cracking due to drying too quickly after application, and enhances the strength after hardening.
2. Ceramic manufacturing industry: Hydroxy propyl methyl cellulose (HPMC) powder is widely used as adhesive in the manufacturing of ceramic products.
3. Coating industry: Hydroxypropyl methylcellulose has a good compatibility in water and organic solvents, so it can be used as a thickener, dispersant and stabilizer in the coating industry.
4. In printing: HPMC can be used as a thickener, dispersant and stabilizer in the ink industry.
5. Pharmaceutical industry: HPMC can be used as coating materials, film materials, rate-controlling polymer materials.
