In the electrical insulation and precision machining industries, material dimensions and performance stability are critical factors when selecting materials. If you are looking for a board with excellent machinability, strong electrical insulation properties, and high temperature resistance, phenolic bakelite sheet is an ideal choice.
We currently supply 1020 × 1220 mm phenolic bakelite sheets in large quantities and offer full-range thickness customization to meet the specific needs of different customers. Whether for large-scale standard component production or special non-standard machining projects, we can provide suitable solutions.
Phenolic bakelite sheets are manufactured by laminating phenolic resin with insulating paper (or cotton fabric) under high temperature and high pressure. The finished material provides excellent mechanical strength and stable electrical performance. Key characteristics include:
High insulation resistance and strong dielectric strength effectively prevent electrical leakage, ensuring safe operation.
Dense structure and high hardness with smooth edges.
The material is easy to machine using turning, milling, planing, drilling, and other processes, and screws can be firmly fixed.
Heat resistance reaches Class B or higher, with minimal dimensional change under temperature variations.
Flame-retardant performance meets UL94 V-0, helping to slow the spread of fire.
Good resistance to oils, weak acids, and certain solvents, making it suitable for various industrial environments.
We provide the standard 1020 × 1220 mm sheet size, which conforms to common industrial board specifications. This size can be directly used for applications such as distribution boxes, fixture plates, and mold clamping plates, helping reduce the cost of secondary cutting.
It is also compatible with commonly used materials such as FR-4 epoxy sheets and fiberglass laminate boards, making it convenient for combined or matching applications.
To meet different operating conditions, we offer a wide range of thickness options suitable for various applications:
3 mm – 10 mm
This is the most common thickness range, widely used for PCB drilling backup boards, fixture plates, and distribution box partitions.
10 mm – 50 mm
Suitable for applications requiring higher mechanical strength, such as mechanical mold clamping plates, surface grinding pads, and packaging machine structural components.
Requirement Communication: Provide information such as the application scenario, required thickness, and order quantity.
Solution Design: Based on your requirements, we recommend suitable material types (such as standard phenolic paper laminate, anti-static phenolic board, or fabric-reinforced phenolic sheet) and appropriate thickness.
Sample Confirmation: Small-batch samples can be provided for performance testing to ensure the product meets your expectations.
Mass Production: Precision lamination processes are used to ensure sheet thickness uniformity within ±0.1 mm.
Fast Delivery: We support 48-hour shipment, helping meet urgent project requirements.
These sheets are widely used in electrical equipment, motor manufacturing, and industrial machinery.
Switchgear insulation partitions, transformer structural components, motor end plates, and power distribution support parts.
Motor end covers, insulation gaskets, and internal structural support components.
Wear-resistant structural parts, insulating base plates, and automation equipment components (CNC precision machining supported).
From precision electronic components to heavy industrial machinery, phenolic bakelite sheets can meet a wide range of industrial manufacturing needs.
With our own production lines, we eliminate unnecessary intermediaries, ensuring competitive pricing and stable supply capacity.
The 1020 × 1220 mm standard size is available with sufficient inventory for fast delivery.
Non-standard thicknesses such as 2.5 mm, 12 mm, and 45 mm can also be customized according to specific requirements.
Each sheet undergoes flatness inspection and dielectric strength testing before leaving the factory, ensuring consistent and reliable quality.
Our 1020 × 1220 mm standard sheets and full-thickness customization services can be tailored to your specific project requirements.
