La description

HPMC, white or similar to white granular powder; odorless. Soluble in water and some organic solvents. There are industrial grade and pharm grade, and widely used in various industries and daily life. CAS NO: ********3 Physical and Chemical Properties: 1、 Appearance: white or similar to white granular powder; odorless. 2、 Particle size: ***0 mesh>*8.5%; **0 mesh>**0%. 3、 Carbonization temperature: ******0°C. 4、 Apparent density: 0.***0.*0/cm³(usually about 0.5/cm³)，specific density 1.***1.*1. 5、 Discolor temperature: ******0°C. 6、 Surface tension: 2% water solution is ****6dyn/cm. 7、 Solubility: soluble in water and some organic solvents, as appropriate proportion ethanol/water, propanol/water, trichloroethane etc. Solution is surfactant, transparent, and stable performance. Different specifications have different gelation temperature. HPMC dissolved in water are not affected by PH value. 8、 HPMC with methoxyl content decreased, the gel point increased, water solubility decreased, surface activity also decreased. 9、 No heat, and was not involved in the metabolism of the human body. Main use: There are two grade in this product, industrial grade and pharm grade. Industrial grade main used in building industry, like retaining agent, retarder, adhesives, water preserving agent, film-forming agent, also used in ceramic industry as adhesives. Pharm grade HPMC is widely used as multi-purpose pharmaceutical excipients, can be used as thickener dispersant, emulsifier and film-forming agent etc. It’s also used in petroleum drilling and daily-used chemicals. Packing: In *5kgs cardboard drum lined with PE or in woven bag with PP lining; stored indoors in dry and draughty palce; avoid rain and sunlight during transporting.
