Three new medical-grade thermoplastic elastomers (TPEs) for biopharmaceutical tubing provide performance superior to the industry standard TPE in this application, making them effective alternatives to widely used silicone. Teknor Apex Company will introduce the new Medalist® compounds at MD&M West and will make a presentation on grades for peristaltic pump applications at the “Tech Theater” during the show.
Teknor Apex recommends three compounds for challenging tubing applications in the biopharma industry for peristaltic pumps and extreme low temperature applications. The materials designed for peristaltic pump tubing provide the elasticity required to keep pace with rapid pump action and the durability needed for the tubing to retain its shape and remain intact over time. In comparison with the industry-standard TPE alternative to silicone, the Medalist TPEs exhibit lower levels of spallation—the shedding of particles from the inner and outer surfaces of the tubing caused by repeated compression and release during pump operation.
These three Medalist compounds exhibit significantly lower permeability than silicones. They can be sterilized by means of e-beam, gamma irradiation, and ethylene oxide (EtO).
“At a time when silicones are in short supply, Teknor Apex can provide an assured global supply chain for all Medalist TPEs, producing them at ISO-13485-certified facilities in the U.S, and Singapore,” said Ross van Royen, senior market manager of regulated products. “As alternatives to silicone, our three new Medalist compounds provide better performance than the industry-standard TPE used thus far.”
The new Medalist compounds are made with FDA-listed ingredients, are certified at a minimum to the ISO 10993-5 standard for biocompatibility, and are REACH SVHC compliant. They are free of DEHP and other phthalates, BPA, and latex. Standard grades are ADM-free.
