High Quality ESD Bakelite Sheet 3mm to 50mm | Antistatic Phenolic Sheet

by:ZTELEC     Time: 2026-03-3

In precision manufacturing and electronic assembly, electrostatic discharge (ESD) can damage components. A single ESD event can not only destroy precision chips but also ignite dangerous sparks in volatile environments.

This is where high-quality ESD bakelite sheets come in. As a derivative of traditional phenolic laminates, these sheets combine cotton fabric to enhance the mechanical strength of phenolic resin with unique surface resistivity. Whether you need 3mm thin sheets for insulating pads or 50mm heavy-duty sheets for fixture fittings, a thorough understanding of this material is crucial for optimizing your production line.

This guide will comprehensively explore the complete range of antistatic phenolic resin sheets and their advantages in industrial applications.

What are Antistatic Phenolic Resin Sheets?

ESD bakelite sheets, also known as antistatic phenolic resin sheets, are industrial insulating sheets made from phenolic resin as a base material, reinforced with other materials, and processed using special techniques to achieve stable antistatic properties.

Its core characteristics are as follows:

Stable surface resistance range

Excellent electrical insulation performance

High mechanical strength and good wear resistance

Easy to cut, drill and CNC machine

Compared with ordinary bakelite boards, antistatic bakelite sheets are more reliable in preventing static electricity accumulation and discharge.

Antistatic Phenolic Sheet Product Specifications: Thicknesses from 3mm to 50mm

The diversity of thicknesses is one of the core advantages of modern antistatic phenolic resin sheets. Our products cover the most commonly used sizes in the industry, specifically as follows:

3mm – 6mm (Thin Sheet):

This thickness is suitable for backing boards, thin insulating barriers, and PCB (Printed Circuit Board) fixture covers. The thinner profile gives it good flexibility, allowing it to be easily processed into complex shapes.

10mm – 20mm (Medium-Thick Sheet):

This thickness is a mainstay product on assembly lines, ideal for jigs, wave soldering trays, and workbenches with medium load-bearing requirements.

25mm – 50mm (Thick Sheet/Block):

This thickness of phenolic resin sheet is often used for structural supports and heavy-duty fixtures. It is also suitable for complex mechanical components that require both strength and static dissipation.
