Eastman Tenite Butyrate 485A2R30016 Natural Cellulose Acetate Butyrate
Categories:	Polymer; Renewable/Recycled Polymer; Thermoplastic; Cellulosic; Cellulose Acetate Butyrate, Molded
Material Notes:	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 485-10 contains an odor mask and an ultra-violet inhibitor(UVI). It has a plasticizer level of 10%. Applications/Uses: Housewares Recreational Tool handles Toys/Sporting goods
