Product Description
Tenite™ cellulosic plastics are noted for their excellent balance of properties – toughness, hardness, strength, surface gloss, clarity and 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 380-18 has a plasticizer level of 18%. It is resistant to high processing temperatures.
