With the development of the electrical industry, high insulation properties are required. Laminated plastic products with high strength, high temperature resistance and adaptability to various use environments have emerged one after another. Now let’s take a look at where laminates are used?

Phenolic laminated paper cloth board has high mechanical strength, excellent moisture resistance and heat resistance, good electrical properties (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/㎝³, which is half lighter than aluminum. It is widely used in aviation and other structures.

Phenolic laminate products have good resistance to chemical corrosion and are resistant to organic solvents, organic acids and dilute inorganic acids. They are suitable for many chemical equipment and are generally not suitable for alkaline media.

Laminated cardboard can withstand sawing, drilling, turning, milling, planing and other processing. There should be no cracks or slag after processing. The thickness is less than 3mm and can be punched. The cold stamped type does not need to be heated. General models need to be pre-processed. Hot post punching. They are used in insulating parts for high and low voltage electrical appliances and electronic industries respectively.

The processing performance of cloth board is better than that of cardboard and glass cloth board, and the bonding strength and impact strength are higher than that of cardboard. However, it is highly water-absorbent. After absorbing moisture, the electrical insulation property decreases and it is easy to grow mold. It is not suitable for use in hot and humid areas. Therefore, it is generally used as insulating structural parts of low-voltage motors and appliances, such as washers, wedges, screws, etc. There are many types of glass cloth boards, and their properties also vary with different adhesive resins. Compared with other laminates, glass cloth boards have higher mechanical strength and heat resistance. Under high temperature, their bending and resistance Although the tensile and impact strength have decreased, they are still higher than those of plastic board and tape board.

Melamine glass cloth board has high strength, arc resistance and flame resistance, and is especially suitable for marine electrical appliances. Epoxy phenolic glass cloth, silicone epoxy glass cloth, diphenyl ether glass cloth, polyimide glass cloth, polyamide-imide glass cloth, etc. have good dielectric properties and high Heat resistance and flame resistance, so it is an excellent dielectric insulating material. Among them, the epoxy phenolic glass cloth board with the largest output and the widest application is.

Glass cloth panels are widely used in electrical, construction, chemical, electronic, aircraft, aerospace, automobile, electric locomotive and shipbuilding industries due to their excellent performance in many aspects.
