Take You To Understand What Material Laminate Is
Jun 23, 2022
Take you to understand the laminate - the specific material of the laminate is resin-impregnated fibers or fabrics that are laminated. Laminated products can be processed into various insulating and structural parts, which are widely used in motors, transformers, high and low voltage electrical appliances, electrical instruments and electronic equipment. Laminates can be plates, tubes, rods or other shapes.
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. Copper clad laminates for printed circuits have also developed rapidly due to the needs of the electronics industry. my country's electrical and electronic laminates are gradually developed after liberation. Thermosetting laminates in my country have formed a relatively complete series.
Laminate is a whole by lamination and thermocompression of two or more layers of resin-impregnated fibers or fabrics. Laminate properties depend on the substrate and adhesive as well as the molding process. Laminates can be classified into the following two types according to their composition, properties and heat resistance.
(1) Organic substrate laminates - using wood pulp insulating paper, cotton fiber paper, cotton cloth, etc. as reinforcing materials. The long-term use temperature can reach 120 ℃, and synthetic fiber products have also been developed as reinforcing materials.
(2) Inorganic substrate laminates—inorganic glass fiber cloth, alkali-free glass fiber mat, etc. as reinforcing materials. The long-term use temperature is 130~180℃, or even higher, depending on the adhesive resin.
