Electrical grade board, also known as phenolic board or bakelite, is a type of board made by using high-quality bleached wood pulp and cotton flock as reinforcing materials, and phenolic resin, a reaction product of high-purity, fully synthetic petrochemical raw materials, as the resin binder.

Materials
Phenolic Laminated Board: Molding compound made by heat pressing bleached wood pulp impregnated with phenolic resin.
Usage
FR4 PCB: Known for its insulating properties, non-static generation, wear resistance, and high-temperature tolerance, FR4 PCBs are widely used in electronic products as insulating switches and variable resistors, for molds in mechanical applications, and as fixtures on production lines. They are also suitable for use in transformer oil.
Bakelite, a synthetic chemical material, solidifies upon heating and cannot be reshaped into anything else. It is known for its non-absorbent, non-conductive, high-temperature resistance, and high strength properties. Due to its widespread use in electrical products, it has earned this name.
Electronic production tooling fixtures manufacturing, performance testing.

Features

Excellent electrical properties at room temperature, good machinability, density of 1.45, warp less than or equal to 3‰, with superior electrical, mechanical, and processing characteristics. Paper-based FR-4 is a common laminated board and also one of the most widely used and large-scale industrial laminates in the world.
Key Features: Good mechanical strength, antistatic, medium electrical insulation. Made by impregnating insulating paper with phenolic resin, then baked and heat-pressed. Suitable for insulation structural components in motors and electrical equipment with high mechanical performance requirements, and can be used in transformer oil. Good mechanical strength, applicable for PCB drilling pads, distribution boxes, fixture boards, mold clamping plates, high and low voltage wiring cabinets, packaging machines, combs, etc. Suitable for motors, mechanical molds, PCBs, ICT fixtures. Molding machines, drilling machines, table grinding pads.
Imported Epoxy Laminated Board Applications: Suitable for PCB drilling, silicone rubber molds, fixtures, distribution boards, and electrical mechanical parts.


Application

Suited for motors, electrical equipment, and insulated structural components with high mechanical performance requirements. Good mechanical strength, primarily used in the processing and testing of insulation components in ICT, ITE fixtures, testing fixtures, silicone rubber keypads, fixture plates, mold clamps, worktop grinding pads, packaging machines, tea trays, combs, etc.
