Material Notes:

Description: Post-forming canvas phenolic material. Mechanical and electrical properties similar to NP310E. 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.Thickness Tested: 0.062", 0.125", and 0.500".
