X/XX/XXX Paper Reinforced Phenolic Laminate Tubes
NEMA grades X, XX and XXX Paper Reinforced Phenolic has a typical natural color of light tan to brown. These grades are composed of a paper base impregnated with a phenolic resin binder. Phenolics are the oldest, best-known general purpose thermoset 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 as template material or back-up material.
