InvibioÆs PEEK-CLASSIX polymer is a US Pharmacopoeia Class VI thermoplastic designed for
medical device applications requiring blood or tissue contact of less than 30 days, including
catheters, surgical instruments, analytical equipment, blood management and drug delivery
systems. This material is one of the most chemically resistant polymers available and exhibits a superior combination of strength, stiffness and toughness making it ideally suited for medical device applications. Invibio offers PEEK-CLASSIX polymer in black and white unfilled grades.

This agreement enables medical and pharmaceutical companies to purchase custom formulations
and colors directly through Foster, which increases FosterÆs product offerings, and extends
InvibioÆs customer base.

   FosterÆs dedication and focus on providing customized polymer compounds to the biomedical
market is a perfect complement to our portfolio of core PEEK-CLASSIX polymer grades," said
Michael Callahan, President of Invibio. "With this agreement, customers will have a
significantly wider range of material solutions developed from our PEEK-CLASSIX polymer."
"Medical devices are getting smaller while the demand for performance is increasing," said
Larry Johnson, Foster CorporationÆs Director of Sales and Marketing. "In many cases, designs
have been optimized and further advancements rely on unique materials such as PEEKCLASSIX
polymer.

  Our expertise in custom medical formulations will allow us to tailor PEEKCLASSIX polymer compounds to individual requirements in cutting-edge applications."

  Compounds can be formulated by Foster using a variety of additives including radiopaque filler,
fiber reinforcements and a variety of color pigments. These compounds can replace stainless
steel and other metals, resulting in cost-effective, innovative medical applications with
outstanding wear, heat, electrical and chemical resistance.

  Instruments designed with these compounds, could be repeatedly sterilized using conventional sterilization methods without the degradation of its mechanical properties.
