Product Description

Tritan™ EX501 is an amorphous copolyester specifically developed for the Infant Care market. Its most outstanding features are consistent glass-like clarity even after multiple dishwasher cycles. Additionally, Tritan™ EX501 exhibits low taste and odor retention versus cPP, excellent drop impact resistance, and dishwasher durability. Tritan™ EX501 contains a mold release derived from vegetable based sources. Tritan™ EX501 meets infant care sterilization requirements via boiling water or microwave steam sterilization. This new-generation copolyester can also be molded into various applications without incorporating high levels of residual stress. Combined with Tritan™ copolyester's outstanding chemical resistance and hydrolytic stability, these features give molded products enhanced durability in the dishwasher environment, which can expose products to high heat, humidity, and aggressive cleaning agents.

Tritan™ EX501 can be converted into parts using injection molding, injection stretch blow molding (ISBM), and extrusion blow molding techniques.

Tritan™ EX501 copolyester may be used in repeated-use food contact articles under United States Food and Drug Administration (FDA) regulations. Contact an Eastman representative for details on global food contact regulatory clearances.
