GENERAL DESCRIPTION
click to resize photo Heat Stabilized Polypropylene sheet provides all of the outstanding properties found in standard polypropylene, but has been subjected to a special heat-stabilizing process. As a result, this material is able to withstand higher service temperatures with less water absorption than standard polypropylene. It is laser-markable (see photo) and has superior dimensional stability.

The enhanced properties of heat-stabilized polypropylene make this material an excellent candidate for replacement of PBT, Acetal, PTFE, PPO and a number of other high-performance plastics. Recommended sterilization techniques include steam autoclaving and cold sterilization.

As a result, HS Polypropylene is an excellent material for surgical trays, caddies and instrument components.

HS PolyPro is available in white and black colored sheets only. Contact us for size availability.
