Five of the fluoropolymer coatings that Surface Solutions Group applies to medical devices have been tested by an independent laboratory to be free of perfluorooctanoic acid (PFOA), the company says. This includes coatings that often are used as low-friction surfaces for guidewires, hypo tubes, mandrels and similar products.
According to the company, PFOA has been used in the manufacture of fluoropolymers since 1947. When recent laboratory tests showed “significant adverse effects” on animals, EPA added the surfactant to its watch list of chemicals that are potentially hazardous to humans. The agency is developing new rules to minimize human exposure and mandatory implementation of the final version is set for 2015, the company says.
