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'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.
