Eastman Tenite 485E3720008 Cellulose Acetate Butyrate, Clear, Trsp
Categories: Polymer; Renewable/Recycled Polymer; Thermoplastic; Cellulosic; Cellulose Acetate Butyrate, Molded

Material Notes: Applications:
  • Toys/Sporting goods

Product Description: Tenite cellulosic plastics are noted for their excellent balance of properties including 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 485-08 contains an odor mask and an ultra-violet inhibitor(UVI). It has a plasticizer level of 8%.
