Overview
Phenolic (PF CC), also known as laminated phenolic cotton cloth, is a thermosetting composite material made by impregnating layers of cotton fabric with phenolic resin under heat and pressure. The result is a high-strength, rigid laminate that offers good mechanical properties, excellent machinability and superior electrical insulation. It is commonly used in mechanical and electrical applications that require dimensional stability, wear resistance and moderate heat tolerance. Its cotton base gives it a natural self-lubricating quality, which reduces wear in sliding parts and provides a quieter operating environment.
