Teknor Apex has introduced new medical thermoplastic elastomer compounds for injection moulded face masks and cushions which offer performance and cost advantages over PVC and silicones, officials said in a 27 Nov news release.
The officials at the Pawtucket, Rhode Island-based materials supplier added that flexible masks made of clear Medalist-brand 50100 series TPEs retain their shape in packing and storage.
New grades of Medalist 10100 series gels also provide secure cushions for rigid polypropylene masks, officials said.
Teknor will introduce the new compounds at the upcoming MD&M West trade show, 6-8 Feb Anaheim, California.
"More and more, medical device OEMs are choosing Medalist as an alternative to both PVC and silicone for face masks," Teknor executive Ross van Royen said in the release. Van Royen is senior market manager of regulated products for the firm's TPE Division.
He added that, in flexible mask applications, the new Medalist grades provide the same clarity and flexibility as PVC, but with better deformation resistance. They also can be used as "more economical alternatives" to silicone face masks, van Royen said.
Teknor produces Medalist compounds at plants in the US and Singapore. The new materials comply with FDA requirements for food-grade ingredients.
Teknor employs more than 2,000 worldwide and has annual sales of more than $600 million. In North America, Teknor is one of the region's 30 largest makers of compounds and concentrates, according to Plastics News data.
