Product Description
Eastar™ Renew copolyester 6763-25 meets ISO 10993 and/or USP Class VI biocompatibility requirement; Food Contact Status compliant.

Eastar™ Renew 6763-25 is a clear, amorphous material that can be molded and extruded with ease. Its excellent performance properties include clarity, toughness, good melt strength, no dusting, no stress whitening, good heat sealability, easy cutting and thermoforming. Eastar™ Renew 6763-25 may be colored using color concentrates, dry colors, or liquid colorants. Eastar™ Renew 6763-25 can be safely sterilized with proper ethylene oxide, radiation, or electron beam methods without property loss or color shift. Eastar™ Renew 6763-25 provides:

  • Superior, long-term clarity provides easy identification of instruments
  • Excellent puncture resistance and impact toughness ensure package integrity
  • Excellent ability to be subjected to several methods of sterilization, providing flexibility and security to the device manufacturer
  • Excellent optical and physical property stability post sterilization
  • Good melt strength offers wide processing latitude and ease in thermoforming

    The production and trimming of rigid medical trays made from sheet of Eastar™ Renew 6763-25 results in little or no dust or particulates. After the thermoformed trays are made, they are put in polybags. The polybags of trays are then placed in protective boxes for storage or shipment. As long as the polybags in the protective boxes are intact and no outside contamination is evident, the thermoformer or medical device manufacturer should not need to clean the tray prior to packaging a device and sealing the package. If contamination is found on the medical trays and cleaning is required, use a lint-free towel. Blowing the tray out with filtered, deionized, non-lubricated air is also acceptable, assuming this does not stir up dust from the surrounding area. Using alcohol, which could cause crazing, or water, which would not evaporate, is not recommended.

    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.
