|
Medical grade Propylux HS is made from an FDA approved polypropylene resin. Through a unique
heat-stabilizing process, the extruded material is able to withstand higher temperatures with less water
absorption than standard polypropylene. Recommended sterilization techniques for Propylux HS include
steam autoclaving and cold sterilization.
The following physical property information is based on actual tests performed on extruded sheet.
