Ethyl Cellulose Description: 1. Out looking:HPMC is a white or light gray mobile power with odorless and tasteless.2. Soft thermoplasticity. Softening point:135～155℃.fault specific gravity: 0.3～0.4g/cm3 .relative density:1.07～1.18g/cm3 . Melting point:165～185℃and dissolves in water and all kinds of organic solvents. EC has good thermo stability. Minimized ash residuals. No sticking, but acerbity. Can form rigid film. Even at low temperature, it also can has good bending resistance, innocuous, antibiosis. Inertia metabolism. Degradation oxidation oxygenation easily occur when under sunshine or violate radiation.3. Important characteristics1)Hard to burn.2)Good thermo stability.3)Not discolor under sunshine.4)Good flexibility.5)High dielectricity.6)Excellent bast-resistance and acid resistance.7)Fine anti-ageing capacity.8)Good salt-tolerance and moisture resistance.9)Stable for chemicals and not deteriorate for a longtime storage.
