Norplex-Micarta EndurX™ BP15NPN Phenolic Cotton Laminate Sheet
Categories:	Polymer; Thermoset; Filled/Reinforced Thermoset; Phenolic
Material Notes:	Post-forming canvas phenolic material. BP15NPN’s mechanical and electrical properties are similar to BP11EPN. It is made from a cotton fabric weighing more than 4 ounces per square yard and having a thread count of not more than 70 threads per inch in both the warp and filler directions. The binder is a modified phenolic resin system, which permits the material to be heated, formed into a shape and cooled under restraint to hold the newly formed shape.
Key Words:	Cotton, Phenolic, Micarta, Post-forming canvas
