Teknor Apex Co. claims its new rigid PVC compounds can replace polycarbonate in clear medical components.
The company says its Apex SCR compounds are suited to connectors and check valves and similar components. It says the new vinyls show comparable strength, rigidity and high clarity while reducing or eliminating stress cracking that can occur at interfaces between polycarbonate and flexible PVC components such as tubing. Companies typically have tried to avoid PC stress cracking by focusing on the plasticizer formulation in the flexible PVC.
Teknor Apex of Pawtucket, R.I., said Apex SCR meets ISO and USP biocompatibility standards, can be sterilized with ethylene oxide and heating methods, and is easy to process. According to the materials firm, they can provide cost savings where over-engineered resins might be chosen for an end-use.
Y-connectors, cannulae, Luer fittings, suction Yankauers, filter housings and specimen containers are other applications suited to the rigid PVC compounds.
