With the development of the electrical industry, high insulation materials. 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 the phenolic laminates is applied?
The phenolic laminates in the phenolic laminated board has high mechanical strength, excellent moisture resistance and heat resistance, good electrical properties (poor board), easy processing, and is widely used in electrical products. The density of phenolic laminated paper and cloth board is about 1.35g / ㎝³, which is half lighter than aluminum. It is used a lot in aviation and other structures.
Phenolic laminates have good chemical resistance, resistance to organic solvents, organic acids and dilute inorganic acids. They are suitable for many chemical equipment and generally not suitable for alkaline media.
Laminated cardboard in phenolic laminates can withstand sawing, drilling, turning, milling, planing and other processing. After processing, there should be no cracks and slags. The thickness can be punched below 3㎜, and the cold punching type does not need heating General models need to be punched after preheating. They are used for insulating parts of high and low voltage electrical appliances and electronics industries.
The phenolic laminated board has better processing performance than paperboard and glass cloth board, higher adhesive strength and impact strength than paperboard, but has higher water absorption, reduced electrical insulation after moisture absorption, and is prone to mold. It is not suitable for use in hot and humid areas. Therefore, it is generally used as the insulating structural parts of low-voltage motors and electrical appliances, such as gaskets, slot wedges, and screws. There are many types of glass cloth panels, and their performance varies with different binder resins. Compared with other laminates, glass cloth panels have higher mechanical strength and heat resistance. Under high temperature, their resistance to bending and resistance Although the tensile strength and impact strength have been reduced, they are still higher than those of paperboard and cloth board.
The melamine glass cloth in the phenolic laminate has high strength, arc resistance and flame resistance, and is especially suitable for marine electrical appliances. Epoxy phenolic glass cloth board, silicone epoxy glass cloth board, diphenyl ether glass cloth board, polyimide glass cloth board, polyimide glass cloth board, etc. Heat resistance and flame resistance, so it is an excellent dielectric insulating material. The largest and most widely used is epoxy phenolic glass cloth board.
Because of its excellent performance in many aspects, glass cloth sheets in phenolic laminates are widely used in industries such as electrical, construction, chemical, electronics, aircraft, aerospace, automotive, electric locomotives and ships. If you have this need, you can contact us!
