On September 19, participants and vendors gathered in East Providence, Rhode Island, for Tritan on Tour: an exclusive event hosted by Eastman and NN, Inc. showcasing how new materials and manufacturing processes can improve medical device performance. Representatives from Henkel, PolyOne, Dukane, Manta, Goddard, and Ensinger were on hand to share the latest advancements in medical injection molding applications.

Attendees learned how to select the best materials and streamline the manufacturing process, and strengthen the future of health care. They also got the opportunity to network with manufacturers, design engineers, and distributors, and discuss solutions for working with Eastman Tritan™ copolyester.

Thanks to all who attended and made this a fantastic event! If you'd like more information please visit our website http://www.eastman.com/Markets/medical/Pages/Introduction.aspx

我们经常收到有关使用Eastman医用级聚合物进行模塑成型的问题，并始终乐于答疑解惑并提供更多信息。以下是对我们最近收到的一个咨询请求的回复：
 
“Eastman MXF221共聚聚酯的热变形温度是多少？”
 
热变形温度（HDT）是聚合物或塑料在指定载荷下变形的温度。此处概述了我们最新产品Eastman MXF221 共聚聚酯的HDT。
 

热性能
变形温度
	在0.455 MPa（66 psi）的压力条件下	ASTM D 648	94°C（201°F）
	在1.82 MPa（264 psi）的压力条件下	ASTM D 648	83°C（181°F）

 
 
MXF221 is a biocompatible, fully compounded medical grade polymer that is uniquely suited for medical devices and electronic device housings. Developed from Eastman Tritan^™ copolyester, MXF221 offers superior chemical resistance to stringent disinfectants and drugs, improved durability, and greater longevity.
 
Thermal control is critical for injection molding. Keeping temperatures cooled below the HDT of MXF221 helps ensure successful demolding with no dragging or sticking of parts. Preparing a cooling strategy early in the tool design process can pay big dividends in cycle time and processability.

Eastman Tritan^™共聚聚酯具有独特的加工和性能特性，包括透明度、韧性、耐热性和耐化学性。它通常也可以替换到现有模具中，只需对加工参数进行最小的调整。与许多其他常用的聚合物相比，这种性能和加工的全面平衡使Tritan具有优势和设计灵活性。在医疗市场模制零件方面，使Tritan成为理想选择的一些特质包括：
 

• 韧性：卓越的韧性和耐用性。由Tritan制成的医疗设备外壳具有抗冲击和防摔性能，并且能够承受极端条件。
• 透明度：在伽马和电子束灭菌前后具有出色的透明度和保色性。
• Chemical resistance: Maintains part integrity when exposed to a wide range of harsh chemicals and disinfectants. This excellent chemical resistance also means improved ESC resistance during solvent bonding and other secondary operations.
• Heat resistance: Higher level of heat resistance, which some devices require to deliver their intended performance or for accelerated aging validation.
• Reduced scrap rates: Less defects due to black specks, flow marks, cracking, and breakage.
• No annealing required: Greater throughput and higher yield.
• Sustainability: Made without BPA, halogens, or ortho-phthalates.
