Hydroxypropyl methylcellulose Hpmc powder
Our company has advanced liquid-phase reaction kettle and adopts the latest production technology to produce powdered hydroxypropyl methyl cellulose, which has been used as thickener, stabilizer, emulsifier, excipient, water-retaining agent and film-forming agent in the production of thermal insulation mortar, petrochemical industry, building materials, paint remover, agricultural chemicals, ink, textile printing and dyeing, paint, ceramics, paper making, cosmetics and other products. In building construction, it is used for wall laying, plastering, caulking, bonding ceramic tiles, marble, and high bonding strength, which can reduce the amount of cement used. It can significantly improve its water retention and bonding strength when used in plastering gypsum, bonding gypsum and water-resistant putty. Cement gypsum secondary products. Daily chemical shampoo, detergent, etc.

This product is industrial grade HPMC
1. Soluble in water and some solvents, such as ethanol/water, propanol/water, trichloroethane, etc. in proper proportion. The aqueous solution has. High transparency and stable performance. The gel temperature of products of different specifications is different, and the solubility changes with the viscosity. The lower the viscosity, the greater the solubility. The performance of HPMC of different specifications is different, and the dissolution of HPMC in water is not affected by the PH value.
2. With the decrease of methoxy content, the increase of gel point, the decrease of water solubility and the decrease of surface of HPMC.
3. HPMC also has the characteristics of thickening ability, salt resistance, low ash powder, PH stability, water retention, dimensional stability, excellent film forming property, and extensive enzyme resistance, dispersion and adhesion.
Precautions for packaging, storage and transportation
Packed in cardboard drums lined with polyethylene film, net weight of each drum: 25kg. Protect from sun, rain and moisture during storage and transportation.
