COCs challenge nylon, PVC for medical bags


The initial application for the industry's first cyclic olefin copolymer (COC) elastomer is expected to debut soon in an extruded medical application.

The newly developed material targets plastics such as nylon and polyvinyl chloride (PVC) in medical applications including tubing and bags. The benefits of the COC elastomer for film are toughness, purity and moisture barrier.

"These transparent polymers are candidates for applications requiring toughness and flexibility," said Timothy Kneale, president of TOPAS Advanced Polymers, Inc. (Florence, KY) in an interview with Plastics Today. The polymer is more expensive than nylon or PVC, but it offers in-plant recyclability making the economics more competitive.
