Product Description

   
                                                                         Ethyl Cellulose EC Pharmaceutical Grade

 

Ethyl Cellulose is a white, tasteless, odorless, non-toxic granule or powdery, it is stable in light and heat Softening temp. 135-155°C, Melting point165-185°C. Ethyl cellulose is soluble in common solvent, It is compatible with varieties of resins and plasticizer. The film and plastic articles made form ethyl cellulose have good mechanical strength and toughness at higher or lower temperature.
