| Tritan™ EX401, specifically developed for the Infant Care market, is an amorphous copolyester with excellent appearance and clarity. Tritan™ EX401 contains a mold release derived from vegetable based sources. Its most outstanding features are clarity, excellent toughness, hydrolytic stability, and heat and chemical resistance. Tritan™ EX401 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™ EX401 can be converted into parts using injection molding, injection stretch blow molding (ISBM), and extrusion blow molding techniques. Tritan™ EX401 copolyester may be used in repeated use food contact articles under United States Food and Drug Administration (FDA) regulations. Contact Eastman representative for details on global food contact regulatory clearances. Eastman Tritan™ EX401 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™ EX401 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.&& |
