Producer: 
Eastman
Eastman Cellulose Acetate (CA-398-3, Food Contact) is one of the lower viscosity solution grades of cellulose acetate. The average ASTM viscosity of CA-398-3, Food Contact is 3 seconds. Eastman CA-398-3, Food Contact is supplied in the form of a fine, dry, free-flowing powder. This multipurpose rheology enhancer, provides high strength and good resistance to ultraviolet light, heat, oils and greases. It is used in lacquers for glass, plastic, wire and release coatings. It may be blended with appropriate solvents, plasticizers, and other modifying resins to formulate coatings for paper, glass, plastic, wire screen, and electrical wiring. When CA-398-3, Food Contact is dissolved in appropriate solvents a clear, colorless solution is produced.Eastman CAB-398-3, Food Contact is based on cellulose, one of the most abundant natural renewable resources. The calculated approximate bio-content value of 55% for Eastman CA-398-3, Food Contact was determined by using six bio-based carbon atoms per anhyroglucose unit divided by the total number of carbons per anhyroglucose unit. Although the value reported is not specifically measured for bio-carbon, it can be estimated based on typical partition data.This product is manufactured, stored, handled and transported by Eastman under conditions adhering to current Good Manufacturing Practices for food contact applications. This product meets requirements for use in certain food contact applications under regulations of the U.S. Food and Drug Administration (21 CFR), European Commission (Regulation 10/2011) and the Switzerland Ordinance of the FDHA on materials and articles intended to come into contact with foodstuffs (817.023.21, Annex 10). Contact your Eastman representative or authorized Eastman distributor for specific regulatory compliance documentation.For applications that do not require food contact compliance, please refer to Eastman CAB-398-3.
