Natural Phenolic XX Tube

Phenolic paper-based (X) tubing has been used extensively through the years in various applications and parts in switch gear, transformers, tap changers, munitions, rockets, bushings, sleeves, coil forms, core tubes and casings. Paper phenolic tubing has excellent electrical properties in high humidity conditions. The combination of the high-temperature resistant phenolic resin and a treated paper convolute wound tube provides excellent strength, weather resistance and electrical resistance. Phenolic XX is commonly used as table saw blade inserts. The "X" designations generally distinguish manufacturing processes which result in different levels of electrical properties (i.e., dielectric strengths). Paper-based phenolics are available in a variety of sheet, rod, and tube sizes.
