Membrane manufacturers have relied on Eastman cellulose esters to manufacture high quality membranes via efficient production processes for over 70 years. Today Eastman offers materials specifically for this market, both for industrial applications as well as food and beverage filtration processing.

Eastman Membrane Material M300 is a high-purity cellulose acetate with a very consistent viscosity. Eastman Membrane Materials M203, M210 and M230 are all acetates with increasing molecular weight. All are highly filtered and screened throughout the manufacturing process and offer the versatility formulators need to produce high performing membranes.
