Eastman Tenite™ Butyrate 264E2R30008 Natural Trsp Cellulosic Plastics
Categories: Polymer

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 translucent. Color concentrates are available in let-down ratios from 10:1 to 40:1. Tenite™ Cellulose Acetate Butyrate 264-08 has a plasticizer level of 8%. It meets FDA requirements for certain food-contact applications when supplied in specific FDA color numbers.

Application/Uses:

  • Toys/Sporting goods
