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. So let's go ahead and see where the phenolic laminated plate are used.
Phenolic laminated paper cloth board has high mechanical strength, excellent moisture resistance, heat resistance and good electrical performance (cloth board is poor). It is easy to process and is widely used in electrical products. The density of phenolic laminated paper and cotton board is about 1.35 g/㎝³, which is half lighter than aluminum. It's used a lot in aviation and other structures.
Phenolic laminated products have good resistance to chemical corrosion, organic solvents, organic acids and dilute inorganic acids. It is suitable for many chemical equipment, generally not suitable for alkaline media.
Phenolic laminated paperboard can bear sawing, drilling, milling, gouging and other processes. It will not crack and drop slag after processing. The thickness below 3 mm can be punched. Cold punching type of sheet does not need heating, and general type needs to be preheated after punching. Laminated phenolic paperboard are used for insulation parts of high and low voltage motors and electronic industries.
The processing performance of cloth board is better than paperboard and glass cloth board. The bonding strength and impact strength of phenolic cloth board is higher than paperboard. But its water absorption is high. After moisture absorption, electrical insulation drops, and easy to mold, not suitable for hot and humid areas. Therefore, it is commonly used as insulation structural parts of low-voltage motor, such as gaskets, groove wedges, screws, etc. Glass cloth board has a lot of kinds, its performance also varies with the difference of adhesive resin. Compared with other laminated sheet, phenolic resin glass cloth board has higher mechanical strength and heat resistance. Under the action of high temperature, its bending, tensile and impact strength is reduced, but still higher than tape paper board and tape cloth board.
Melamine glass cloth board has high strength, arc resistance and fire resistance, especially suitable for marine electrical appliances. Epoxy phenolic glass cloth board, organosilicon epoxy glass cloth board, diphenyl ether glass cloth board, polyimide glass cloth board and polyimide glass cloth board, etc. It has good dielectric performance, high heat resistance and fire resistance, so it is an excellent dielectric insulating material. Among them, the largest production and the most widely used one is epoxy phenolic glass cloth sheet.
Because of its excellent performance in many aspects, phenolic glass cloth board is widely used in the industries of electrical, construction, chemical, electronics, aircraft, aerospace, automobile, electric locomotive and ship. If you have this need, you can contact us!
