Phenolic round rod is a type of high-performance thermosetting plastic rod made from phenolic resins, often reinforced with glass or carbon fibers. It offers excellent insulating properties, high mechanical strength, and resistance to heat, chemicals, and moisture, making it suitable for applications requiring electrical insulation, mechanical components, and high-temperature environments such as electrical insulators, bearings, bushings, and other rigid, non-conductive, and thermally stable components.
