This is the RS PRO Natural Polyamide (PA) Sheet, a standard engineering polymer stock material. It is a solid, unlaminated plastic sheet used for cutting, machining, and fabrication into mechanical components, gaskets, and industrial parts. Critical verification: confirm moisture content and storage conditions, as polyamide absorbs 6-7% water which significantly reduces tensile strength from 85 MPa (dry) to 60 MPa (wet).
