Technical Data Sheet
Tenite™ Propionate 377E4861312 Clear Trsp
Equipment & machinery
Packaging components non food contact
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 377-12 has a plasticizer level of 12%. It meets FDA requirements for certain food-contact applications when supplied in specific FDA color numbers.
