Product details

Also known as epoxy fiberglass laminated sheets, our industrial laminated boards are premium composite materials crafted from high-grade electronic alkali-free fiberglass fabrics bonded with pure epoxy resin adhesives. Manufactured under strict high-temperature and high-pressure curing processes, these industrial insulation composites deliver stable physical rigidity, reliable dielectric performance, and outstanding environmental adaptability. The product line covers two globally recognized mainstream grades, including standard industrial grade and flame-retardant high-end grade, which can fully cater to low-cost conventional applications and high-standard safety-sensitive industrial scenarios. Widely trusted in power electronics, automated machinery, and new energy industries, these industrial insulation composites have become essential core components for modern electrical equipment insulation and structural support.

Technical Specifications

We supply standardized and customizable industrial board sizes to meet diverse engineering and machining demands. Standard bulk panel dimensions include 1000×2000mm and 1220×2440mm (4×8ft), which fit most universal industrial installation requirements. The regular thickness range covers 0.5mm to 100mm, while ultra-thin 0.1mm sheets and ultra-thick 150mm customized boards are available for special project needs. Rich color options including yellow, green, and black are provided for different grade configurations.

As reliable Epoxy Resin Board Materials, the two core grades feature distinct performance parameters for differentiated usage. The 3240 yellow board supports a continuous working temperature of 130℃ with an HB flame retardant rating, serving as a cost-effective solution for general insulation projects. The upgraded FR4 board adopts UL94-V0 self-extinguishing flame retardant technology, featuring stronger high-temperature resistance and more stable insulation in dry and humid environments, making it the preferred material for high-end electronics and new energy equipment.

Product Features

This series of laminated boards boasts superior comprehensive performance compared with traditional insulating materials. First of all, it achieves exceptional electrical insulation stability. It maintains consistent dielectric properties in extreme high-low temperature and humid working conditions, with high voltage resistance and breakdown prevention capabilities, effectively eliminating electrical leakage and short circuit risks for electronic and power equipment.

In terms of mechanical performance, the material features high rigidity, excellent bending resistance and impact resistance. It is highly adaptable to precision cutting and shaping processes, supporting professional CNC Machining of Epoxy Boards such as drilling, milling, turning, and grooving. Thanks to stable mechanical toughness, finished insulation material cnc machined parts can replace partial metal components for lightweight structural applications, reducing equipment cost while ensuring structural stability.

The material also excels in environmental resistance. It can withstand erosion from weak acid, weak alkali and organic solvents, with ultra-low water absorption rate. There is almost no insulation performance attenuation in long-term damp working environments. With professional insulation material processing technology, we can retain all original excellent properties of the board while completing customized shaping, ensuring long-term stable service life of finished parts.

Application Scenarios

With stable material quality and flexible processing adaptability, our boards and processed parts are widely applied in multiple core industrial fields. In the power industry, they are commonly used for high-voltage switchgear partitions, terminal blocks, transformer insulation frameworks, and arc extinguishing plates to ensure safe operation of power facilities.

In the PCB and electronics industry, the materials serve as PCB drilling backing plates, wave soldering fixtures, SMT tooling plates, and FPC reinforcing plates, providing precise and stable support for electronic processing. For mechanical automation equipment, customized insulation material cnc machining produces professional insulating gaskets, gears, bearing spacers, and planet wheels, solving insulation and transmission demands for automated equipment.

In the new energy and lithium battery sector, the boards are processed into battery cell insulation partitions, fixture boards, and positioning insulation parts, fully adapting to the high safety and high stability standards of new energy equipment manufacturing.

Customization Options

We provide all-round personalized industrial solutions to meet unique project requirements for global clients. We offer standard and Custom Epoxy Boards with customized sizes, thicknesses, and colors. Whether you need ultra-thin precision sheets or ultra-thick heavy-duty boards, we can complete customized production according to technical drawings.

Besides standard size customization, our core service covers full-process Custom Processing of Epoxy Resin Board. Our professional technical team conducts secondary precision processing including special-shaped cutting, hole opening, grooving, chamfering and surface polishing. We can also adjust material performance parameters targeting special corrosive, high-temperature and high-humidity working scenarios, delivering one-stop customized insulation material solutions for different industrial scenarios.

Production Process

Our finished products adopt standardized and refined production workflows to guarantee stable and reliable batch quality. The whole process starts with strict screening of raw Epoxy Resin Board Materials, selecting high-purity electronic-grade alkali-free fiberglass cloth and high-quality epoxy resin glue as the base materials. After precise proportioning, the fiberglass cloth is fully impregnated with epoxy resin to ensure uniform glue penetration and consistent material composition.

The impregnated semi-finished materials are laminated and stacked according to customized thickness standards, then sent to professional equipment for high-temperature and high-pressure integrated hot-press curing. After molding, the boards are trimmed, polished and surface treated. Combined with precise insulation material processing and testing procedures, all finished products undergo strict tests on insulation performance, pressure resistance, flame retardancy and mechanical strength before delivery. Every batch of products complies with international industrial standards, providing reliable quality assurance for global industrial procurement clients.
