Norplex-Micarta EndurX™ BP21NPM Phenolic Cotton Laminate Sheet, MoS2 Lubricated
Categories:	Polymer; Thermoset; Filled/Reinforced Thermoset; Phenolic
Material Notes:	BP21NPM is composed of a linen substrate combined with a phenolic resin system which contains molybdenum disulfide for reduced wear and increased lubrication. Provides the same lubricity as BP13NPM, but has better machining qualities. The mechanical strength is similar to, but slightly less than BP21NPN. BP21NPM is used in applications where reduced wear is needed in non-conductive applications.
Key Words:	Cotton, Phenolic, Micarta, Molybdenum Disulfide Lubricant
