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：
 
“What is the heat deflection temperature for Eastman MXF221 copolyester?”
 
Heat deflection temperature (HDT) is the temperature at which a polymer or plastic deforms under a specified load. The HDT of our latest offering, Eastman MXF221 copolyester, is outlined here.
 

Thermal properties
Deflection temperature
	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^™ copolyester offers a unique blend of processing and performance properties, including clarity, toughness, and heat and chemical resistance. It can also often be substituted into existing molds with minimal adjustments to processing parameters. This total balance of performance and processing gives Tritan advantages and design flexibility over many other commonly used polymers. Some qualities that make Tritan an excellent choice when it comes to molding parts for the medical market include:
 

• Toughness: Exceptional toughness and durability. Medical device housings made with Tritan are impact- and shatter-resistant and have the ability to withstand extreme conditions.
• Clarity: Outstanding clarity and color retention before and after gamma and e-beam sterilization.
• 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.
