Phenolic board is a kind of insulating board with good performance. It can be used in many fields. Now let us introduce its application types.

With the development of the electrical industry, high insulation. Laminated plastic products with high strength, high temperature resistance and adaptability to various use environments have appeared one after another. Now let's take a look at where is the laminate application?

Phenolic laminated paper cloth board has high mechanical strength, excellent moisture resistance and heat resistance, good electrical performance (poor cloth board), easy processing, and is widely used in electrical products. The density of phenolic laminated paper and cloth board is about 1.35g/cm³, which is half lighter than aluminum. It is used a lot in aviation and other structures.

Phenolic laminates have good chemical resistance and can withstand organic solvents, organic acids and rare inorganic acids. They are suitable for many chemical equipment and generally not suitable for alkaline media.

Laminated cardboard can withstand sawing, drilling, turning, milling, planing and other processing, and there should be no cracks and slag after processing. The thickness of less than 3mm can be punched, the cold punching type does not need to be heated, and the general type needs to be punched after preheating. Respectively used for high and low voltage electrical appliances and insulation parts in the electronics industry.

The processing performance of the cloth board is better than that of paperboard and glass cloth board, and the adhesive strength and impact strength are higher than that of paperboard. However, the water absorption is large, the electrical insulation is reduced after moisture absorption, and it is easy to grow mold, which is not suitable for use in hot and humid areas. Therefore, it is generally used as insulation structural parts of low-voltage motors and appliances, such as washers, slot wedges, and screws.

There are many types of glass cloth boards, and their performance varies with different binder resins. Compared with other laminates, glass cloth board has higher mechanical strength and heat resistance. Under the action of high temperature, its bending resistance, tensile strength and impact strength are reduced, but they are still higher than that of rubber paper board and rubber cloth board.

Melamine glass cloth board has high strength, arc resistance and flame resistance, especially suitable for marine electrical appliances. Epoxy phenolic glass cloth board, organic silicon epoxy glass cloth board, diphenyl ether glass cloth board, polyimide glass cloth board, polyamine-imide glass cloth board, etc., with good dielectric properties and higher Heat resistance and flame resistance, so it is an excellent dielectric insulating material. Among them, the most widely used is epoxy phenolic glass cloth board.

Because of its excellent performance in many aspects, glass cloth panels are widely used in industries such as electrical, construction, chemical, electronics, aircraft, aerospace, automobiles, electric locomotives, and ships. If you have any needs in this regard, you can contact us!
