Our ESD FR4 epoxy fiberglass laminate (also known as anti-static fiberglass board) is a high-quality industrial composite material. It is composed of high-performance woven fiberglass fabric and advanced anti-static epoxy resin, tightly pressed together under high temperature and high pressure.

Unlike inexpensive sheets with temporary coatings, our material incorporates conductive particles—such as high-quality carbon black—uniformly into the matrix. This ensures stable, long-lasting electrostatic discharge (ESD) protection that will not wear or wash off, while maintaining a surface resistivity of 10⁶–10⁹ Ω to safely dissipate static charges without generating sparks.

Wuxi Shangjue Technology Co., Ltd. offers three professional-grade categories to meet your structural layout and budget constraints:

1.Single-sided anti-static sheet: Features a dual-color structure. One side is black and anti-static (10⁶–10⁹ Ω), while the other is light green, offering electrical insulation and high-temperature resistance.

2.Double-sided anti-static sheet: Consists of a high-dielectric-constant, aqua-green core sandwiched between two layers of high-quality black anti-static material.

3.Fully encapsulated anti-static board: Offers complete three-dimensional uniformity. Every part—including internal surfaces exposed after deep CNC machining or milling—maintains identical anti-static properties.

• Our custom ESD FR4 sheets provide reliable protection and structural integrity for extensive electronics and automotive supply chains:

  • Electronics Manufacturing: PCB ICT/FCT test fixtures, bases for precision testing instruments, and surface pads for electronic assembly workbenches designed to protect IC components.

  • New Energy Sector: Inter-cell insulation gaskets for high-discharge lithium battery packs, solar photovoltaic backsheet trays, and insulation for heavy-duty electric vehicle (EV) components.

  • Precision industrial housings: protective covers for electronic components, high-voltage capacitor substrates, protective platforms for laser cutting tables, and laboratory vacuum chambers.

  • Advanced robotics technology: UAV (Unmanned Aerial Vehicle) robotic arms, structural frames/mounts, and automated factory electrical panels.

• • Excellent heat resistance and flame retardancy: withstands continuous operating temperatures up to 180°C. Certified to the UL94 V-0 self-extinguishing flame retardancy standard.

  • Superior surface flatness: A smooth, defect-free surface—devoid of pits or bubbles—enabling the precise placement of sensitive microchips.

  • Excellent moisture and chemical resistance: Low water absorption ensures high dimensional stability in humid cleanroom environments, resisting warping, twisting, and chemical solvent attack.

  • High mechanical strength and machinability: High flexural strength makes it a robust chassis for industrial control cabinets, while it maintains clean cutting edges during machining.
