I am a firefighter developing a product for personal protective equipment. The piece I am creating is a knee pad with a plastic impact shell and foam padding. I have very little knowledge on the vast variety of plastics available. There are limitations to what I can use. The plastic needs to be fire resistive with a melting point of 500 deg F. It will need to have good impact qualities and not be brittle. The plastic shell will be about 0.1875 thick. I will need to be able to use an industrial machine to stitch the padding to it. Does anyone have suggestions on what type of plastic would be best for this application? We will most likely be injection molding this but a thermoform is possible too.
