Product Description Brief IntroductionHydroxypropyl Methyl Cellulose (HPMC) is non-ionic cellulose ether made from natural polymer cellulose through seriesof chemical processes. It contains almost all properties of methyl cellulose (MC) and is the first choice for the production ofhigh-quality building materials additives. HPMC has the characteristics of thickening, dispersing, emulsifying, film forming,suspension, adsorption, surface activity, moisture retention and protective colloid. It is suitable for construction dry mortar,caulking compound, interface agent, coating, and self-leveling agent for new building materials.HPMC Properties1. Water RetentionWater retention will be improved, which helps to solve the problem of cement or gypsum construction materialsdrying too fast and poor hardening or cracking due to insufficient hydration.2. WorkabilityIt can enhance the plasticity of mortar and improve the coating efficiency in construction projects.3. AdhesivityIt can make mortar attach to base material better since the plasticity of mortar is enhanced.4. Slip ResistanceIt can prevent slipping problem between mortar and the base material in construction project as a result of itsthickening effect.Physical Properties ItemIndexAppearanceWhite or slightly off-white powderParticle Size80 mesh 100% sieving rateViscosity (Brookfield RV2% 20°C)100-80000 cpsLoss on drying (wt%)≤5.0Salinity (wt%)≤5.0Technical Index HPMCModelDN65DN70DN75Methoxyl Content (%)17.0-22.016.5-20.019.0-24.0Hydroxypropyl Content (%)4.0-9.56.0-12.04.0-12.0Gel Tempreture (°C)59-6868-7570-90Moisture Content (%)≤5.0≤5.0≤5.0Ash Content (%)≤4.0≤4.0≤4.0PH Value5.0-8.55.0-8.55.0-8.5Viscosity Range Spec.Viscosity ByBrookfieldViscosity ByNDJ-1 Spec.Viscosity ByBrookfieldViscosity ByNDJ-1400350-550350-550 1500010000-1500012000-18000800650-1000650-1000 4000024000-3200030000-5000015001200-18001200-1800 7500032000-4000050000-9000025002000-30002000-3000 10000038000-4500080000-12000040003200-48003200-4800 15000045000-67000120000-18000080006400-96006400-9600 200000≥67000≥180000 ???
