Material Notes:

Description: NP321 consists of a fine weave cotton fabric (linen) impregnated with a phenolic resin binder. Applications include vanes for air and liquid pumps, and compressors. NP321 remains very flat during fabrication and in the application. Wear resistance is improved by the addition of a lubricant in the system.Thickness Tested: 0.062", 0.125", and 0.500".
