Fabric 3025 Phenolic Cotton Laminated Sheet are manufactured by modified phenolic resin as binder and pure cotton fabric as reinforcement. They have exceptionally good heat resistance and will not creep under high temperature conditions. These grades are composed of cotton fabric impregnated with phenolic resin binder. They have good mechanical properties and toughness, good heat resistance and moisture resistance, excellent wear resistance, and easy to machine. Cotton based grades have greater mechanical strength than paper based grades.

NEMA grades X, XX and XXX Paper Reinforced Phenolic - natural color is typically 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 is outstanding for use as template material and/or backup material. A good rule of thumb in selecting a paper grade is to 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., XP, XXP, XXXP.
NEMA grades C and CE canvas Cotton-Cloth Reinforced Phenolic - natural color is typically light tan to brown. These grades are composed of a continuous cotton woven cloth impregnated with a phenolic resin binder. (Phenolics are the oldest, best-known general-purpose thermoset resins. They are among the lowest 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.) These grades contain a medium weave canvas and are known primarily for their mechanical properties. These grades are not recommended for primary electrical insulation.
