Description
Material Notes:
Plasticizer 14%. Weight loss on heating = 0.6% 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 translucent. Color concentrates are available in let-down ratios from 10:1 to 40:1. TENITE Cellulose Acetate Propionate 358-08 has a plasticizer level of 8%.Applications: Medical; OphthalmicTechnical Data Sheet Characteristics: Formula 358 – base. 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 given.Information provided by Eastman Chemical.
