Specification: Items HPMC Methoxyl content (-OCH3),w/% 20.0-28.0 Hydroxypropyl content (-OCH2CHOOHCH3),w/% 5.0-11.0 Gelling temperature, °C 55-80 Moisture content ,w/% max 1% Residue on ignition,w% max 1.5% Lead (Pb), ppm max 2 Arsenic (As) ,ppm max 2 Heavy metal max 20 Viscosity index Viscosity range (mpas) 1500 1200-2000 4000 3500-4500 8000 7000-9000 10000 9000-11000 15000 13000-17000 20000 18000-22000 40000 35000-45000 75000 65000-85000 100000 85000 150000 130000-180000 200000 >180000 Advantages: 1. Water soluble and thickening ability: this product is soluble in cold water, and it can form transparent sticky solution. In organic solvent of dissolved: because it contains a certain amount of hydrophobic methoxyl, this product is soluble in some organic solvent; it is also soluble in water and organic mixed solvent. 2. Hydroxypropyl methyl cellulose (HPMC) salt resistance: because ion and the polyelectrolytein exists in this product, its metal salt or organic electrolyte aqueous solution is stable. 3. Surface activity: HPMC for daily chemical aqueous solution has the surface activity, ensuring its emulsification, protective colloid and relative stability. 4. Low ash content: because ion exist in this product, in preparation process we can use hot water washing for effective refinement, so its ash content is very low. 5. pH stability: HPMC aqueous solution viscosity in the range of pH3.0-11.0 is more stable. 6. Water retention effect: this product is hydrophilic and its solution has high viscosity. 7. Film-forming property: HPMC can generate strong pliable and transparent sheet, which has the good oil resistance to ester performance. Application: l. used as adhesives, thickeners, water-binding agents, emulsifiers, film-forming reagents, dispersing agents and stabilizers in the pharmaceutical industry 2. used as adhesive and water-binding agents in building industry. 3. used as thickeners, dispersing agents and stabilizers in paint, printing and ink industry. 4. used in plastic industry for forming release agents, softeners, lubricants and so on. 5. used in the leather and paper industries, fruit and vegetable fresh-maintaining and textile industry and so on.
