Redefining the balance between toughness and …

1 Redefining the balance between toughness and heat new-generation copolyesterEASTMAN Medical PolymersEastman better prepared thanever to meet your packaging trends are driving an increased need for innovative,compliant, and reliable medical devices and combines industry experience and polymer capability to help OEMs stay ahead of these trends. By adding Eastman Tritan copolyester MP100 to its provenpolymer portfolio, Eastman Chemical Company hasstrengthened its offering for customers in the rigid medicalpackaging market Eastman Tritan copolyester MP100 is an enhanced-performance copolyester.

2 This medical-grade polymer delivers a unique balance of design, processing, and performance advantages. It offers all the advantages of Eastar copolyester 6763,the industry standard for rigid medical packaging for thepast 20 years. In addition, Tritan MP100 delivers higher heat resistanceand greater inherent toughness than Eastar and otherpolymers, including acrylic multi-polymer and acrylonitrile resins. Strengthening a proven portfolio Eastman Tritan copolyester MP100 includes the sameproperties that have made Eastar copolyester 6763 theindustry standard for rigid medical packaging, includingchemical resistance, clarity, and toughness .

3 Tritan MP100 offers extrusion, thermoforming, and sealing properties that are similar to Eastar. In addition, Tritan MP100 offers the advantages of higherheat resistance and greater toughness , which satisfyunmet needs for some applications. The launch of Tritan MP100 follows the successful introduction of medical-grade Tritan for molded medicaldevices and housings.

7 Of EastmanTritan copolyester MP100 provides advantages for sterilization and durability. These advantages can translateto timely rewards for customers who specify Tritan for rigidmedical packaging: Allows more rapid accelerated-aging protocols fasterand more reliable shelf-life qualification can help reducetime, labor, and go-to-market delays Higher sterilization chamber temperatures are not limitedby the package, allowing faster EtO cycle time and reduced risk of warping and sticking. Slower aging and increased shelf life provide greater confidence.

8 Here s one more clear advantage to throw into the package. Eastman Tritan copolyester MP100 delivers unmatchedclarity, seen in its high level of light transmittance, lowlevel of haze, and minimal color shift even after EtO orgamma radiation. This provides some valuable benefits forthe quality perception of your brand: Outstanding post-sterilization clarity and color, comparedwith other polyesters and, especially, other competitivematerials Rapidly returns to crystal clarity following gamma sterilization Higher-quality appearance throughout packaging life cycle Eastman Tritan copolyesterTemperature resistance testing to 90 CEastman Tritan copolyester and ANEach tray was heated to 90 C for 10 minutes.

9 Although these were extreme temperatures, EastmanTritan copolyester did not warp or of what you expect from Tritan copolyester MP100 delivers the same reliable results as Eastar copolyester 6763 throughout the extrusion, thermoforming, and heat-sealing shrinkage and heat-sealing parameters of Tritan are all similar to Eastar 6763. When less is more making packaging more toughness of Eastman Tritan copolyester MP100provide an opportunity to redesign the packaging to reducethickness, which requires less source material and may result in reduced shipping costs and energy use.

10 Tritan also can reduce the need for secondary packaging, such as complicated cardboard and foam all Eastman medical-grade copolyesters, Eastman Tritan copolyester MP100 is free of many compounds that create disposal problems, including halogens, orthophthalate plasticizers, and bisphenol-A(BPA). Tritan also is free of chlorine, which helps managethe risk of generating polychlorinated pollutants during incineration of medical more robust portfolio for themedical Chemical Company has supplied a wide range ofmaterials for the medical market for more than 65 , as always.
