Proteus™ LSG HS PP-H (Life Science Grade, heat-stabilized) stock shapes are made from high purity polypropylene resin that has undergone additional filtration to remove the last remaining black particles, thus increasing purity. The material is pre-assessed for biocompatibility at the stock shape level for bioprocessing applications according to USP VI and ISO 10993 and is supported for use in non-body contacting medical applications.
Heat-stabilized to provide improved dimensional stability and a higher heat deflection temperature compared with standard polypropylene grades, Proteus™ LSG HS components can withstand repeated steam sterilization cycles and autoclaves and are highly resistant to cleaning agents, disinfectants and various solvents. For these reasons, Proteus™ LSG HS is a strong candidate for medical non-body contact applications such as surgical trays, caddies and device housing components.
