HEC

Alsdee hydroxyethy cellulose (HEC) is a nonionic water-soluble polymer derived form cellulose it is a cellulose ether ,but it differs in that it is nonionic and its solution are unaffected by cations .Alsdee dissolves readily in cold or hot water .Its solution have somewhat different flow properties from those obtained with other water soluble polymers .It is used to produce solutions having a wide range of viscosity .Such solutions are pseudoplastic that is ,they vary in viscosity depending on the amount of shear stress applied . propertyStandardMoisture, wt%≤6Ash,wt%≤5Transparency,% (2% solution)≥70pH(1% water solution)5.5 8Viscosity typeAll viscosities are determined at 25°C,using a Brookfield LVT viscometer with spindle and speed combinations depending on viscosity level. While ‘s’ means speediness dissolution, and ‘r’ means retard dissolution.TypeConcentration,%Viscosity, mPa·sspindle /speed(rpm)15s, 15r5100 1801/30350s,350r2250 4502/602000s,2000r21500 25003/306000s,6000r24500 65004/6015Ms,15MR11000 15003/6030MS,30MR11500 24003/3050MS,50MR12400 30003/30100MS,100MR13500 44004/60Note: Special products can be provided according to the require of customers.
