CA-398-6

CA-398-6 is a low viscosity solutions grade cellulose acetate polymer.  It is commonly used as the main film former in paper, paperboard, and wood coatings.  Coatings formulated with CA-398-6 offer superior chemical, heat, and UV resistance and will outperform coatings made from nitrocellulose.  CA-398-6 has been approved by the FDA to be used in paper and paper board coatings that will come into contact with food.  Additionally, CA-398-6 can be cast into durable films that are useful as tape backing.  Films made from CA-398-6 are strong, clear, and chemically resistant making them an ideal polymer for membrane manufacturing.  Membranes composed of cellulose acetate like CA-398-6 have excellent resistance to fouling and can be cleaned using chlorine, acids, and bases.  This makes cellulose acetate membranes ideal for filtration operations with a high risk of membrane fouling like dairy processing, beverage clarification, waste water treatment, and desalination.  In addition, cellulose acetate membranes have a natural ability to separate CO2 from CH4.  This is why cellulose acetate is the most commonly used membrane material for spiral wound and hollow fiber membranes for natural gas filtration.
