What is the phenolic cloth
Phenolic laminated cloth is made of cotton impregnated with phenolic resin, after baking, hot pressed. Heat resistant grade E. With high mechanical properties, oil resistance and dielectric properties of phenolic board, high mechanical strength, excellent in moisture resistance and heat resistance, good electrical properties (less layout), easy processing, 3025 phenolic layout widely used in electrical products. Phenolic laminated paper, board density of about 1.35g/ cm, 50 percent lighter than aluminum, many in aviation and other structure.
3025 phenolic resin pressing material has good chemical resistance and can resist organic solvent, organic acid and rare inorganic acid. It is suitable for many chemical equipment and is not suitable for alkaline medium.
3025 phenolic laminated board can withstand sawing, drilling, milling, planing, car and other processing, after processing should not crack and drop the thickness of 3 mm below the punching process, without heating cold punching type, general type by punching after preheating. Respectively used in high and low voltage electrical machinery, electrical and electronic industry insulation parts.
