Products detail
Product Name: | Hydroxypropyl Methylcellulose(hpmc) | |
CAS No: | 9004-64-2 | |
Product Type: | Synthesis Material Intermediates | |
Product spec: | 28-30% | |
Packing: | plastic-plated polypropylene woven bag,net weight:20kg | |
Post Time: | 2010-12-03 | |
Usage: | HPMC is mainly used as dispersant in the production of PVC and as thickener,stabilizer,emulsifier,excipient,water retention agent,film-forming agent in petrochemical,building materials,agrochemical,ink,printing and dyeing of textile,paper making,cosmetic,etc. | |
Description: | (1)Appearance:white or off-white powder (2)Particle size:throughput efficiency of above 98.5% in 100 mesh,and 100% in 80 mesh. (3)Carbonization temperature:280-300°C (4)Apparent density:0.25-0.70g.cm3(usually about 0.5g/cm3),specific gravity:1.26-1.31. (5)Color degradation temperature:190-200°C (6)Surface tension:42-56dyn/cn(2% aqueous solution) (7)Soluble in water and some organic solvents:its aqueous solution is of surface tension,high transparency and stable property.The solubility varies with the viscosity,the lower the viscosity is ,the higher solubility it has.The different HPMC is different is different in some properties and its solubility in water is not affected by PH. (8)The lower methoxyl content in HPMC,the higher gelatification temperature,the lower solubility in water and surface activity. (9)HPMC has also other characteristic such as thickening property.PH stability,water retention,excellent film-forming property and good disperse and adhesion power. |
