Mitsubishi Chemical Advanced Materials Proteus™ LSG HS PP-H Heat Stabilized Polypropylene

Categories:

Polymer; Thermoplastic; Polypropylene (PP)

Material Notes:

Life Science Grade, Heat Stabilized PP-H stock shapes, made from high purity homopolymer polypropylene resin. Shapes are pre-assessed for biocompatibility at the stock shape level (USP VI & ISO 10993) and are supported for use in non-body contact medical applications. Exhibits superior resistance to steam sterilization, cleaning agents, and disinfectants over standard PP materials, and has improved dimensional stability.
