Product Description Product Description Sodium Carboxymethylcellulose sodium,White powder.Density 0.5-0.7 g/cm 3, almost odorless, tasteless, hygroscopic. Easy to disperse in water into a transparent colloidal solution, insoluble in organic solvents such as ethanol. The pH of 1% aqueous solution is 6.5 ~ 8.5, when pH>10 or <5, the viscosity of glue is significantly reduced, and the performance is best when pH=7. Stable to heat, the viscosity rises rapidly below 20 ° C, changes slowly at 45 ° C, and long-term heating above 80 ° C can denature its colloid and significantly decrease its viscosity and performance. Easily soluble in water, the solution is transparent; In alkaline solution is very stable, in the case of acid is easy to hydrolysis, PH value is 2-3 when precipitation, in the case of polyvalent metal salts will also react precipitation.Packaging & Shipping 25kg/bag COAItemStandardPhysical FormWhite to off-white powderViscosity(1% mPa.S)3000-4000Degree of Substitution0.70-0.90Purity,%99.5minpH Value 1%6.5-8.5Loss on drying, %8.0maxSodium Chloride, %0.5maxHeavy Metals (As Pb), ppm10.0maxlron, ppm2maxLead, ppm2maxAs, ppm3maxHg, ppm1maXCd,ppm1maXTotal plate count, cfu/g500/g maxYeast & Moulds, cfu/g100/g maxE.Coli, cfu/gNil/gColiform bacteria, mpn/gNil/gSalmonella, cfw/gNi1/25g
