Eastman Tenite Butyrate 485A2R30023 Natural, Trsp Cellulose Acetate Butyrate  (discontinued **)
Categories: Polymer; Renewable/Recycled Polymer; Thermoplastic; Cellulosic; Cellulose Acetate Butyrate, Molded

Material Notes: Plasticizer 23%. Weight loss on heating = 1.2% 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 cellulosic 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 485-23 contains an odor mask and an ultra-violet inhibitor(UVI). It has a plasticizer level of 23%.

Applications: Housewares; Recreational; Tool handles; Toys/Sporting goods

Formula 485 - odor mask; UVI.
