Introduction of Processability of Phenolic Laminate Board

Phenolic laminated cloth board is made of cotton cloth soaked with phenolic resin, baked and hot pressed. The heat resistance grade is e. With high mechanical properties, oil resistance and certain dielectric properties, phenolic cloth plate has high mechanical strength, good moisture resistance and heat resistance, good electrical properties (cloth plate is worse), easy to process, 3025 phenolic cloth plate is widely used in electrical products. The density of phenolic laminated paper and cloth board is about 1.35g/cm, which is half lighter than aluminum. It is widely used in aviation and other structures.

Phenolic laminated cloth board products have good chemical corrosion resistance, can resist organic solvent, organic acid and dilute inorganic acid. It is suitable for many chemical equipment, and generally not suitable for alkaline medium.
Phenolic laminated cloth board can withstand sawing, drilling, turning, milling, planing and other processing. After processing, there shall be no cracks and slag falling. For punching with thickness less than 3mm, heating is not required for cold punching. For general models, preheating is required before punching. They are respectively used for insulation parts of high and low voltage electrical machinery and electronic industry.

Phenolic laminated cloth board has better processing performance than cardboard and glass cloth board, higher adhesive strength and impact strength than cardboard, but it has large water absorption, and its electrical insulation is reduced after moisture absorption, and it is easy to grow mold, so it is not suitable for use in hot and humid areas. Therefore, it is generally used as the insulation structural parts of low-voltage motor, such as washers, slot wedges, screws, etc. There are many kinds of glass cloth board, and its performance varies with the adhesive resin. Compared with other laminates, glass cloth board has higher mechanical strength and heat resistance. Under the high temperature action, its bending, tensile and impact strength is lower, but still higher than that of rubber cardboard and rubber cloth board.
