Insulation materials are essential functional materials for electrical equipment, power systems, electronics, transportation, machinery and other industrial applications. Phenolic paper laminates are widely used because they combine good electrical insulation, mechanical strength, dimensional stability, oil resistance and machinability.

Phenolic Paper Boards are commonly used for electrical insulation plates, spacers, barriers, structural components, switchgear parts, transformer and motor components, tooling applications and other machined insulation parts. As demand for reliable insulation materials continues to grow across electrical and industrial manufacturing, selecting a supplier with stable production, processing capability and quality control is increasingly important.

YILONG is an integrated manufacturer specializing in the research, development, production, machining and technical service of electrical insulation materials. With its own manufacturing facilities and precision processing capabilities, YILONG provides both standard insulation sheets and customized components for industrial customers.

Phenolic Paper Boards for Electrical and Industrial Applications

Phenolic Paper Boards are rigid laminated materials manufactured from cellulose-based insulating paper and phenolic resin through controlled impregnation, pressing and curing processes. The combination of paper reinforcement and phenolic resin provides a practical balance of mechanical and electrical properties.

Depending on the grade and application, the material can be used for mechanical insulation components, low-voltage electrical equipment, transformer parts, switchgear components, tooling and various structural applications.

YILONG offers several phenolic paper laminate grades, including PFCP201, PFCP202 and PFCP203, allowing customers to select a suitable material according to their mechanical, electrical, thermal and machining requirements.

PFCP201

PFCP201 is designed for mechanical and low-voltage electrical applications where good machinability, mechanical strength and electrical insulation are required. It is suitable for insulation structural components and various fabricated industrial parts.

PFCP202

PFCP202 is developed for applications with higher electrical insulation requirements. It can be used for electrical insulation components and selected transformer-related applications where stable electrical performance is important.

PFCP203

PFCP203 provides a balanced combination of mechanical and electrical properties. It is suitable for insulation components, structural parts and customized machined products requiring reliable material performance and good machinability.

YILONG Integrated Manufacturing and Machining Capability

YILONG is not only a supplier of Phenolic Paper Boards, but also provides integrated precision machining services for customers who require finished insulation components.

The manufacturing facilities include automatic impregnation production lines, large-format machining equipment and automated hydraulic pressing equipment. YILONG also operates a 2,000-ton automated CNC press to support stable and consistent laminate production.

The company's annual insulation board production capacity exceeds 35,000 tons, while precision machining capacity exceeds 5,000 tons per year. With approximately 98 CNC and related processing machines, YILONG can handle both large-volume material orders and customized machining projects.

Complete Processing Services

YILONG provides a wide range of machining processes according to customer drawings, samples and technical specifications.

Available processes include sawing, turning, milling, planing, grinding, drilling, tapping, punching, shearing, edge milling and CNC machining. Depending on the design of the component, additional processes such as precision grinding and finishing can also be arranged.

This integrated capability allows YILONG to complete the process from sheet cutting and forming to final machining and inspection, helping customers reduce the need to coordinate multiple suppliers.

Quality Control from Raw Material to Finished Product

Stable material performance depends on consistent control throughout the manufacturing process. YILONG has established a quality management system covering raw materials, impregnation, pressing, machining and final inspection.

YILONG has obtained ISO 9001 quality management system certification and has been recognized as a high-tech enterprise for multiple years. Its products have also undergone RoHS testing and relevant electrical material quality testing.

Every production batch is subject to quality inspection before shipment. For customized components, dimensional accuracy, machining quality and appearance are checked according to the agreed requirements. Finished parts are cleaned, inspected and properly packed before delivery.

Customized Phenolic Paper Boards Solutions

Different electrical and mechanical applications require different material thicknesses, dimensions, tolerances and machining processes. YILONG therefore provides customized Phenolic Paper Boards and finished insulation components based on customer drawings or samples.

Customers can provide technical drawings, samples or application requirements. YILONG's technical team evaluates the material grade, dimensions, machining method and inspection requirements before production.

For precision components, the production process can cover material cutting, forming, CNC machining, drilling, tapping, grinding and final inspection. This allows YILONG to provide a complete solution from insulation material to finished component.

Applications of Phenolic Paper Laminates

The combination of electrical insulation and mechanical properties makes Phenolic Paper Boards suitable for a variety of industrial applications.

Electrical Equipment and Switchgear: Typical applications include insulation plates, barriers, spacers, supports and structural components for electrical equipment, distribution cabinets and switchgear.

Transformers and Motors: Selected grades can be used for insulation components in transformers and motors, including structural parts and fabricated electrical insulation components.

Machinery and Tooling: The material's machinability also makes it suitable for mechanical parts, tooling components, fixtures, backing plates and other industrial applications requiring a rigid and machinable insulation material.
