Eastman Tenite Butyrate 285A2R30016 Natural, Trsp Cellulose Acetate Butyrate (discontinued **)
Categories:	Polymer; Renewable/Recycled Polymer; Thermoplastic; Cellulosic; Cellulose Acetate Butyrate, Molded
Material Notes:	Plasticizer 8%. Weight loss on heating = 0.3% per ASTM D 707. Soluble matter loss = 0.1% per ASTM D 570. Product Description: TENITE cellulosic plastics are noted for their excellent balance of properties - toughness, hardness, strength, surface gloss, clarity, and a warm feel. The mechanical properties of TENITE cellulosic plastics differ with plasticizer levels. Lower plasticizer content yields a harder surface, higher heat resistance, greater rigidity, higher tensile strength, and better dimensional stability. Higher plasticizer content increases impact strength. TENITE cellulose plastics are available in natural, clear, selected ambers, or smoke transparents and black translucents. Color concentrates are available in let-down ratios from 10:1 to 40:1. TENITE Cellulose Acetate Butyrate 285-16 has a plasticizer level of 16% and contains an odor mask. Applications: Medical; Tool handles Technical Data Sheet Characteristics: Formula 285 - odor mask. Comments: Properties reported here are typical of average lots. Eastman makes no representation that the material in any particular shipment will conform exactly to the values give Information provided by Eastman Chemical.
