Product Description
Eastman Tritan™ Renew EX501-50 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 Renew EX501-50 exhibits low taste and odor retention versus cPP, excellent drop impact resistance, and dishwasher durability. Tritan Renew EX501-50 contains a mold release derived from vegetable based sources. Tritan Renew EX501-50 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 Renew EX501-50 can be converted into parts using injection molding, injection stretch blow molding (ISBM), and extrusion blow molding techniques.

Tritan Renew EX501-50 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.

Tritan Renew EX501-50 copolyester is included in Eastman Chemical Company’s Customer Notification Procedure which details our policy for customer notification when significant changes are made in Tritan™ Renew EX501-50 sold into the infant care market. This procedure provides the infant care industry an added layer of confidence in the consistent quality and performance of Tritan™.

Eastman Renew polymers have been certified by International Sustainability & Carbon Certification (ISCC), a global, independent agency for tracking sustainable content in a variety of industries. Renew polymers are produced with ISCC certified circular content by mass balance allocation.

Renew polymers enable a brand to reduce consumption of fossil feedstock-based plastics, achieve sustainability targets without compromise, and be a fast mover in a growing market for sustainable consumer products.
