Polypropylene combined with styrenic block copolymers (SBCs) from Kraton are rapidly penetrating medical markets as a replacement for polyvinyl chloride (PVC) in intravenous bags and tubing.
"You're seeing traction in the marketplace for viable alternatives to PVC," John Marx, global industry manager in the Advanced Materials Group at Kraton, told PlasticsToday in an interview. "We're seeing growth year over year." The growth last year was particularly remarkable—about 91% in the IV market alone.
"The trending toward PVC alternatives began six to eight years ago and we were at the forefront of that," said Marx. "You're basically now seeing the market acceptance and the continuing pressures to move away from PVC."
