Teknor Apex to present new medical TPEs for face masks at MD&M West

Teknor Apex has announced to introduce two new families of medical-grade TPEs for injection moulded face masks at MD&M West, which will held from 6 - 8 February 2018 in Anaheim, CA, USA. The new compounds include a deformation-resistant series for flexible masks and a series of gels that provide a gas-tight cushion for rigid ones moulded from polypropylene.

Medalist 50100 Series TPEs for flexible masks are more deformation-resistant than PVC and, as thermoplastics, provide a more economical alternative to silicones, says Teknor Apex. In respiratory therapy oxygen masks, the Medalist TPEs provide a comfortable fit on the face yet retain their shape during packaging and storage, without need for inserts. Their PVC-like transparency facilitates patient monitoring. Medalist 50100 Series compounds are available in 58, 68, and 73 Shore A hardness.

Medalist 10100 Series TPE gels for rigid-mask cushions bond to polypropylene in insert or two-shot moulding, providing an alternative to the traditional air-filled PVC “balloon” cushions that must be glued onto the rigid component. According to Teknor Apex, the cushion conforms to the patient’s face to ensure a gas-tight fit that is more secure than the PVC cushion and has a lower profile on the face. Grades in the series include a clear 8 Shore A compound and a translucent one with 18 Shore A hardness. Pre-coloured compounds are available to enable device manufacturers to differentiate their product offerings, so it said.

"More and more, medical device OEMs are choosing Medalist as an alternative to both PVC and silicone for face masks,” said Ross van Royen, senior market manager of regulated products for the TPE Division of Teknor Apex. “In flexible mask applications, the Medalist MD-50100 series provides the same clarity and flexibility as PVC, but with better deformation resistance, allowing for improved packaging and storage. These materials can also be used as more economical alternatives to silicone face masks."

Teknor Apex produces Medalist compounds in ISO-13485 facilities in the USA and Singapore. The new materials comply with FDA requirements for food-grade ingredients, ISO 10993-5 standards for biocompatibility, and REACH SVHC directives. They are free of DEHP and other phthalates, BPA, and latex. Standard grades are ADM-free.
