What is phenolic paper sheet?

Phenolic paper sheet is a type of board that uses phenolic resin as a binder and presses multiple layers of paper or paperboard through a specific process. Phenolic resin is a thermosetting resin made by polycondensation of phenolic compounds (such as phenol, cardanol, etc.) and aldehyde compounds (such as formaldehyde) in the presence of a catalyst. This resin has excellent heat resistance, corrosion resistance, water resistance and electrical insulation properties, so phenolic paper sheet also inherits these characteristics accordingly.

Performance characteristics of phenolic paper sheet

1. Excellent mechanical properties: Phenolic paper sheet has high density, high hardness, high strength, strong pressure resistance, and is not easy to deform, crack or break.

2. High strength and wear resistance: Phenolic paper sheet has high strength and hardness. So it can withstand greater pressure and friction, and is not easy to deform or damage.

3. Excellent fire resistance: Phenolic paper sheet has excellent fire resistance, is not easy to burn, and does not produce toxic gases during combustion. This feature makes phenolic paper sheet an ideal fireproof material in the fields of construction, furniture and transportation. When a fire occurs, phenolic paper sheet can effectively prevent the spread of the fire and buy precious time for escape and rescue.

4. Corrosion resistance: Phenolic paper sheet has strong resistance to corrosive substances such as acids, alkalis, and salts.

5. Good electrical insulation performance: Phenolic paper sheet has high electrical insulation performance and can withstand high voltages without breakdown or leakage. This feature makes phenolic paper sheet an ideal insulation material in the fields of electrical equipment and electronic products.

6. Environmentally friendly and healthy: Phenolic paper sheet is non-toxic, odorless, non-radioactive, and is a green and environmentally friendly material.

Application fields of phenolic paper sheet

1. Electronic industry: Phenolic paper sheet is widely used in electrical insulation, electronic instruments, measuring instruments, etc. due to its excellent insulation performance. For example, it is used in switch components, insulating electrical appliances, line insulation parts, sockets, electrical signals, etc., with a long service life and safe and reliable operation.

2. Mechanical industry: Due to the high hardness and strength of phenolic paper sheet, it is also widely used in machine manufacturing, automobile manufacturing, textiles, shipbuilding, aerospace and other fields. For example, it is used in machine gears, springs, transmission belts, brake pads, fasteners, etc.

3. Construction industry: Phenolic paper sheet is often used in the manufacture of building materials and the production of building fireproof materials due to its fire resistance, heat insulation, sound absorption, sound insulation and moisture resistance. For example, it can be used in building sound insulation, sound absorbing materials, thermal insulation materials, etc., which can effectively isolate sound and heat sources.

As a multifunctional insulation material, phenolic paper sheet has broad development prospects in the market with its excellent performance characteristics and wide range of applications. In the future, with the continuous advancement of technology and the continuous changes in the market, phenolic paper sheet will continue to innovate and bring more convenience and comfort to people's lives and work. At the same time, enterprises should also strengthen technology research and development and market research, and continuously improve the quality and performance of products to meet consumer needs and market development.
