NP318

It (NEMA CF) is a post-forming canvas phenolic material, which is composed of a cotton fabric and a modified phenolic resin system that allows the material to be heated, formed into a specific shape, and then cooled under restraint to hold the newly formed shape. NP318 does not meet the NEMA requirement for non-afterglow for Grade CF, but is used for applications by Boeing Aircraft, with exemption of the non-afterglow requirement.
