What is bakelite sheet?

Bakelite sheet is a commonly used insulating material. It is a phenolic laminated sheet made of bleached wood paddle paper soaked with phenolic resin. It has the characteristics of insulation, no static electricity, wear resistance and high temperature resistance‌. It plays an important role in the power industry and electronic engineering.

What is phenolic cotton sheet?

Phenolic cotton sheet is a composite material with phenolic resin as the main component. It is usually made by mixing cotton cloth with phenolic resin and then processing it at high temperature and pressure. This material has excellent mechanical properties, water resistance, heat resistance and chemical stability and is widely used in the construction, furniture and home appliance industries.

The differences between a phenolic cotton sheet and a bakelite sheet

1. Different material sources: phenolic cotton sheet is made of chemically synthesized phenolic resin as the base material, while the bakelite sheet is made of natural wood as the raw material.
2. Different performance characteristics: phenolic cotton sheet has wear resistance, high temperature resistance, chemical corrosion resistance and other characteristics, while the bakelite sheet has excellent insulation performance, fire resistance and moisture resistance.
3. Different production process: phenolic cotton sheet is formed by high temperature and high pressure, while the bakelite sheet is specially treated and impregnated.
4. Different application fields: phenolic cotton sheet is widely used in electrical appliances, machinery and other fields, while bakelite sheet is mainly used in the power industry.

How to choose the right material?

Due to the different performance characteristics and application field of phenolic cotton sheet and bakelite sheet, the selection of materials should be determined according to the specific application scenario. If it is used in a harsh environment such as high temperature, high pressure, chemical corrosion, it is recommended to choose phenolic cotton sheet; If it is used in the power industry, it is recommended to choose a bakelite sheet.

The uses of bakelite sheet phenolic cotton sheet

Electrical engineering: phenolic cotton sheet is also widely used in the field of electrical engineering, such as for power system insulation structure, high voltage switchgear, transformer insulation, cable insulation and so on. Its excellent insulation and heat resistance can ensure the normal operation of electrical equipment and power system.
Electrical equipment manufacturing: phenolic cotton sheet is commonly used as insulation material for electrical equipment, such as insulation support, insulation board, insulation gasket and other components manufacturing. These insulating parts can effectively isolate the conductive part of the electrical equipment and prevent leakage or breakdown phenomenon and ensure the safe operation of the equipment.
Thermal barrier insulation: Because phenolic cotton sheet has good heat resistance, it is also commonly used as thermal barrier insulation material for thermal insulation, thermal insulation or fire protection applications.

The uses of bakelite sheet

1.‌ Machinery and mold: The bakelite board has high hardness and good wear resistance, so it is often used in the manufacture of fixtures and molds. It is widely used in PCB drilling pad, distribution box, fixture board and other aspects ‌.
2.‌ Electronic products: Bakelite board is often used in the manufacture of electrical components such as switch sockets, fuses, and insulating partitions for power tools and appliances. Its good insulation properties and mechanical strength make it an indispensable material in electrical equipment ‌.
3.‌ Medical and health: Bakelite board can replace metal to make artificial bone, which has the advantages of light weight, non-toxic and strong corrosion resistance, and is widely used in precision medical instruments and artificial bone ‌.
4.‌ Automotive industry: The characteristics of light weight, high mechanical strength, heat resistance, self-lubrication and so on to meet the needs of the automotive industry. Bakelite board is used for the production of various parts, such as bearings, piston rings ‌.
5.‌ Aerospace: Due to the superior comprehensive performance of the bakelite board, it has been widely used in aerospace products abroad and domestic J-8-II aircraft and Shenzhou spacecraft products successfully tried since the 1990s‌.
