Proteus® LSG HS PP-H

Homopolymer Polypropylene

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.
