Phenolics are the oldest, best-known general purpose themoset resins. They are among the lowest in cost and easiest to process. Phenolics are quite adequate for a fair percentage of electrical applications. Generally speaking, they are not equivalent to epoxies in resistance to moisture, humidity, dimensional stability, shrinkage and retention of electrical properties in extreme environments. The paper reinforced phenolic has good electric strength properties with fair mechanical strength and are outstanding for use as template material and/or back-up material.

 

When selecting a paper grade phenolic, remember the more X's the better the electrical properties, while the fewer X's represent superior mechanical properties.

 

Paper grades can be modified by adding plasticizers to make them more conducive to part punching resulting in a P suffix added to the X designation, i.e., Phenolic Grade XP, Phenolic Grade XXP, Phenolic Grade XXXP.

 

Phenolic Grade X certifies to Mil-I-24768/12 PBM 

Phenolic Grade XX certifies to Mil-I-24768/11 PBG
