Bakelite Sheet Fundamentals | Features and Selection Points of Phenolic Resin Laminate

The greatest features of phenolic laminate sheets are their excellent electrical insulation and moderate mechanical strength. They are difficult for electricity to pass through, making them suitable as insulating components for distribution boards and electronic devices. Another advantage is their good machinability, allowing for easy processing with milling machines and lathes. Furthermore, since they are available at a relatively low cost, they are also suitable for mass-produced parts. On the other hand, their heat resistance is limited compared to engineering plastics, and they may degrade in prolonged high-temperature environments. Additionally, paper-based types have water absorption properties, so it is necessary to note that performance changes may occur depending on the humidity environment.
