Product Description:
Hydroxypropyl methylcellulose (INN name: Hypromellose), also simplified as hydroxypropyl methylcellulose (HPMC), is a variety of nonionic cellulose mixed ethers. It is a semi-synthetic, inactive, viscoelastic polymer .This product is industrial grade HPMC, mainly used as the dispersing agent for PVC production and as the main assistant used in producing PVC suspension polymerization.
It is also used as thickener, stabilizer, emulsifier, excipient, water retention agent, and film-forming agent etc.in producing petrochemicals, building materials, paint removers, agricultural chemicals, inks, textiles, ceramics, paper. cosmetics and other products.
Main uses:
1, construction industry: as a cement mortar water retention agent, slow coagulant so that mortar has pumping. In plaster, gypsum, putty powder or other building materials as a adhesive, improve applicability and extend the operating time. Used as paste tile, marble, plastic decoration, paste enhancer, but also reduce the amount of cement. HPMC's water retention performance allows the slurry to crack too fast after application, enhancing the strength of the hardening.
2, ceramic manufacturing industry: in the manufacture of ceramic products widely used as adhesive.
3, the coating industry: in the coating industry as thickeners, dispersants and stabilizers, in water or organic solvents have good solubility. As a delacor.
4, ink printing: in the ink industry as thickener, dispersant and stabilizer, in water or organic solvents have good insoluble.
