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. |
