Bakelite is a man-made synthetic chemical substance, once it is heated and shaped, it will solidify and cannot be shaped into other things. Because of its non-absorption, non-conductivity, high temperature resistance, high strength, etc., and it is widely used in electrical products, it is named. Bakelite board now has important applications in mechanical mold manufacturing, electronics, and electrical appliances. The reason for today's achievement is inseparable from its performance parameters.

Characteristics of bakelite board

All parts of the anti-static bakelite board have the same anti-static value, and the overall resistance value is 10^8-10^10Ω, which has stable anti-static performance. After machining or surface wear, the anti-static value does not change. It is resistant to organic solvents, does not dissolve at room temperature, and the use temperature is -20-120℃. It has high mechanical strength and excellent processing performance.

Main application of bakelite board

PCB drilling, jigs, switchboards, mechanical parts, test benches, SMT technical work benches.

The use of bakelite board

Because of its insulation, no static electricity, abrasion resistance and high temperature resistance.Bakelite board has become the insulation switch and variable resistance of electronic products, molds for machinery and fixtures on the production line, and can be used in transformer oil and other products. . Electrical laminated wood is an insulating and supporting material widely used in transformers and transformers. It has the advantages of moderate specific gravity, high mechanical strength, easy vacuum drying and easy mechanical processing. Its dielectric constant is close to that of transformer oil, and the insulation coordination is reasonable. It can be used in transformer oil at 105°C for a long time.

Electrical laminated wood has been widely used in oil-immersed transformers to make parts such as upper and lower pressure plates, lead brackets, iron yoke pads, etc., and used to make clamps in transformers. It replaces steel plates, insulating cardboard, epoxy cardboard, The application of epoxy glass cloth board in these aspects reduces the weight and material cost of the transformer. Electrical laminated wood board is a veneer made of high-quality birch wood by steaming, peeling and drying. After coating with special insulating glue, it is made by high temperature and high pressure.
