3025 Phenolic Cotton Cloth Laminated Sheet

Phenolic Insulation Board for Electrical and Machined Parts

The 3025 phenolic cotton cloth laminated sheet is a kind of bakelite sheet, which is a phenolic laminated sheet made from cotton cloth and phenolic resin under high temperature and pressure.

It is also known as phenolic laminated sheet, phenolic cotton cloth sheet or cotton fabric bakelite sheet. Compared with phenolic paper laminated sheet, cotton cloth reinforced phenolic sheet has better toughness, impact resistance and machinability. It is commonly used for electrical insulation parts that need both mechanical strength and stable insulation performance.

In electrical equipment factories and machining workshops, this material is often selected for bushings, washers, spacers, support plates, insulating pads and other CNC machined insulation parts.

Chengrui supplies 3025 phenolic cotton cloth laminated sheet in different thicknesses and sheet sizes. Cutting, drilling and drawing-based machining can also be discussed according to customer requirements.

Advantages of Phenolic Cotton Cloth Sheet

1. Good Machinability

Phenolic cotton cloth laminated sheet is suitable for cutting, drilling, milling, turning and punching.

It can be processed into insulating washers, bushings, spacers, support plates and customized insulation parts. For buyers who need finished parts instead of full sheets, machinability is one of the most important reasons to choose this material.

2. Better Toughness Than Phenolic Paper Board

Because the sheet uses cotton cloth reinforcement, it has better toughness and impact resistance than paper-based phenolic laminated sheet.

This makes it more suitable for parts working under mechanical stress, friction or repeated assembly pressure.

3. Electrical Insulation Performance

The phenolic resin system provides electrical insulation performance for low-voltage and general electrical equipment applications.

It can be used as an insulating structural material in motors, electrical apparatus, machinery and transformer-related environments.

4. Oil Resistance

3025 phenolic cotton cloth laminated sheet has oil resistance and can be used in transformer oil applications where phenolic cotton cloth material is suitable. For special oil-immersed applications, customers should confirm working temperature, oil condition and part design before order.

Applications

• Electrical Insulation Parts

Phenolic cotton cloth laminated sheet is widely used in electrical equipment where insulation and mechanical support are required at the same time.

• Machined Phenolic Insulation Parts

Many buyers do not use full sheets directly. They cut or machine the sheet into finished parts: bushings, sleeves, gaskets or customized CNC insulation parts.

• Transformer-Related Applications

3025 phenolic cotton cloth laminated sheet can be used in transformer-related environments, including applications in air and transformer oil, depending on the final working condition.

Typical uses include insulating supports, spacers and machined insulation parts.

Phenolic Cotton Cloth Sheet vs Phenolic Paper Sheet

Choose phenolic cotton cloth laminated sheet when the part needs better toughness, machining performance or friction resistance.

Choose phenolic paper laminated sheet when the application mainly needs a cost-effective flat insulation board.
