NP338 Phenolic Sheet – Dual-Layer High-Performance Material

NP338 is a combination of two Norplex-Micarta grades, NP310 which is a canvas phenolic, on one side of the laminate, and NP315, a canvas phenolic with graphite added as a solid lubricant on the other side of the laminate. Material is conductive to electricity and should not be used where conductivity is detrimental to the application.
