• Bulk density:0.25-0.70g/cm3 (Ususlly around 0.5g/cm3).
• Real specific gravity: 1.26-1.31.
• Browning temperature: 190-200°C;
• Surface tension:(2%water solution) 42-56dyn/cm.
• Properties:Dissolved in water and some organic solvent such as etdanol.propyl alcohol.etdylene chloride,tde water solution is of surface activity.lt is a nonionic surface active agent.Gelation temperature is different for different grades.For example,among 60RT HPMC,60 is gelation temperature,namely,2%water solution will form gelation at 60°C.
• CAS 42dyn/cm HPMC Hydroxypropyl Methylcellulose is a pharmaceutical auxiliary material. It plays an important part in tdree fields:
• Tablets and granules coating.
• Controlled release of course,it can be used for many otder uses,such as PVC polymerization,construction products,foods,and personal care product.
• Place tde required amount of hot water heated to above 85°C,and HPMC gradually added while stirring gently,at first HPMC floats on tde Surface of tde water,but it is gradually dispersed to torm a uniform slurry,cool tde slurry while stirring it.
• Put one-tdird or two-tdirds of tde required qmount of water,heat to above 85 °C in a vessel.disperse HPMC and prepare a hot slurry while stirring,cool tde resultant mixture.
