Gentex (Zeeland, Michigan) has agreed to jointly develop materials for the medical tubing market with Natvar (Clayton, North Carolina), a subsidiary of Tekni-Plex (Sommerville, New Jersey).
Natvar will be granted a license to Gentex's Clearweld laser welding technology to compound, produce, and sell near infrared absorbing products in medical tubing applications.
The Clearweld process employs specialty infrared absorbing additives that are compounded directly into plastic resins to laser weld medical tubing and connectors. These laser-absorbing materials focus laser energy and convert it into heat. Localized heating at the interface of the laser and tube produces strong, hermetically sealed welds with minimal thermal and mechanical stress and no particulates making it ideal for medical applications.
This new technology will eliminate the need for solvents or adhesives used in assembly operations for many medical device applications today.
Clearweld was developed jointly by TWI (Great Abington, UK), an industrial research and development organization that specializes in material joining, and Gentex, which retains the sole right to commercialize the technology worldwide.
Gentex is a privately owned corporation with four operating units: Helmet Systems, Performance Materials, Respiratory Products and Electro-acoustic Products. The company makes high-performance products and systems for both the military and commercial markets with extensive research and development capabilities.
Natvar bills itself the leader in tubing extrusion technology for the medical and industrial markets. Natvar specializes in providing close-tolerance tubing components for such applications as intravenous therapy, hemodialysis equipment, cardiovascular procedures, urinary drainage, and catheterization.
