AdvanSource Biomaterials Corporation (NYSE Amex: ASB), a leading developer of advanced polymer materials for a broad range of medical devices, today announced the recent filing of a patent for its newly launched ChronoSil polymer product, a silicone-urethane copolymer. This patent application relates to silicone-urethane copolymers and methods for making ChronoSil. ChronoSil can have many physical properties which are usually associated with polyurethanes, but also the feel and characteristics of silicones.

The ChronoSil product family maintains the inherent benefits of a polycarbonate-based urethane, including high pressure resistance, tensile-strength and superior chemical resistance combined with silicone’s industry-recognized advantages such as heightened elongation, superior elasticity and a low coefficient of friction.

Michael Adams, President and CEO, stated, “We were pleased to announce our new biomaterial product, ChronoSil, a thermoplastic silicone polycarbonate urethane, which was exhibited at the recent MEDTEC IRELAND Medical Design and Manufacturing Exhibition and Conference in Galway, Ireland. Two of the objectives that are key to our business strategy include the development of innovative biomaterials to meet the needs of medical device developers and manufacturers while building additional value through a growing portfolio of patented products. This recent patent application supports our commitment to both of these objectives. We are pleased with the efforts of our research and development team and look forward to continued innovation from this talented group of scientists and engineers.”
