RESINEX Adds Trinseo’s Biocompatible PS for Medical Devices to its Portfolio

RESINEX has recently added STYRON™ 2678 MED, a biocompatible polystyrene from Trinseo, to its portfolio of polymers. 

ISO Compliant Biocompatible PS:
This general purpose injection molding grade has undergone testing based on ISO 10993 standards and is suitable for use in approved medical applications. It combines the versatility of polystyrenes with the specifically high reliability of supply needed in this industry, and it meets extended demands in terms formulation lock, notification of change and lot traceability. 

Typical applications include clear rigid packaging, diagnostic components, petri dishes and housings for test kits.


Special Characteristics:
Beyond the general advantages of polystyrene, such as outstanding transparency, high stiffness, rigidity and heat resistance, STYRON™ 2678 MED also provides further special characteristics required for medical devices including chemical resistance to fight infection. The material can be sterilized by ethylene oxide (EtO) and shows very good radiation stability when subjected to gamma- or e-beam sterilization, even at high doses. STYRON™ 2678 MED may also be processed further with secondary operations such as solvent bonding, welding and laser marking, typical for medical devices.

Hence, STYRON™ 2678 MED opens new applications for polystyrenes, going beyond those of general purpose food grades.
