NP612 Phenolic Sheet – Flexible, Durable Electrical Insulation
Room temperature punching and shearing paper phenolic grade up to .125" thick. NP612 is more flexible with lower mechanical properties than NP611, and is intended for applications where electrical and moisture requirements are of secondary importance. NP612 meets the requirements of MIL-I-24768/20 and IEC-60893-3-4-PF CP 207.
