Cellulose Acetate(CA)
- Composition: Mixture of triacetate and diacetate
- Characteristics:Low static charge and high strhgth
- Sterilizable: May be repeatedly sterilized without loss of integrity or change in bubble point
- Clean: 0.1 wt% aqueous extractables
-
Related to MCE membranes: - improved solvend resistance to low molecular weight alcohols - better heat resistance - lower protein binding
