What is The Hardness of Bakelite (Phenolic Laminated PaperBoard)?

Bakelite boards and Bakelite sticks are also called Bakelite boards/sticks and phenolic laminated paperboards/sticks....

Bakelite boards and Bakelite sticks are also called Bakelite boards/sticks and phenolic laminated paperboards/sticks. They are made of high-quality bleached wood building paper and cotton linter paper as reinforcements, and phenolic resin made from high-purity, fully synthetic petrochemical raw materials as resin adhesives.

Main features of Bakelite boards and Bakelite sticks:
Good mechanical strength, anti-static, intermediate electrical insulation, made of insulating impregnated paper impregnated with phenolic resin, baked and hot pressed. This product is suitable for insulating structural parts in motors and electrical equipment with high mechanical performance requirements, and can be used in transformer oil. It has good mechanical strength and is suitable for PCB drilling pads, distribution boxes, jig boards, mold splints, high and low voltage distribution boxes, packaging machines, combs, etc. Suitable for motors, mechanical molds, PCBs, ICT jigs. Molding machines, drilling machines, table grinding pads.
