Conductive Polyethylene Foam Washers
At Advanced Seals & Gaskets Ltd, we specialise in manufacturing and supplying conductive polyethylene foam washers — precision-engineered components designed for use in electrical, packaging, and industrial applications. As one of the UK’s leading gasket and washer suppliers, we offer a vast range of polyethylene foam grades and densities, allowing us to deliver the perfect solution for every project.
Polyethylene foams are among the most versatile materials available, offering excellent performance in both industrial and electrostatic discharge (ESD) environments. One of the most effective types is conductive polyethylene foam, which combines durability with high conductivity — ideal for protecting sensitive components from static electricity.
Our conductive foam washers are custom-made to your specifications, ensuring a perfect fit and function. Each washer is cut in-house from block foam, which can be split to thicknesses as low as 1.5mm and supplied in sheet or roll form before conversion. Whether you need a single prototype or a large production run, we manufacture to the highest standards with rapid turnaround times.
Custom Manufacturing Process
Every conductive polyethylene foam washer we produce is made to order using your supplied dimensions, CAD drawings, or samples. Our production team uses advanced machinery — including atom and auto presses, travelling head presses, kiss-cutting equipment, and CNC oscillating knife cutters — to ensure accuracy and efficiency for every batch.
Depending on your needs, washers can be supplied plain, self-adhesive backed, foil laminated, or combined with other materials for enhanced performance. We can deliver them loosely packed or kiss-cut on rolls for easy integration into automated production lines.

What Are Conductive Polyethylene Foam Washers?
Conductive polyethylene foam washers are precision-cut rings featuring an Outer Diameter (OD), Inner Diameter (ID), and specific thickness, designed to sit between two surfaces to distribute pressure evenly, create seals, or act as spacers.
Unlike standard polyethylene foams, conductive PE foam contains carbon additives that provide permanent conductivity. This ensures electrostatic charges are safely dissipated through the washer rather than accumulating and damaging sensitive equipment.
The result is a high-performance, ESD-safe washer that offers long-term durability and protection. These properties make conductive foam washers suitable for use in electronics manufacturing, telecommunications, medical devices, and precision engineering applications.
Why Use Conductive Polyethylene Foam Washers?
In industries where static-sensitive components are handled, even a slight electrostatic discharge (ESD) can cause irreversible damage. Conductive polyethylene foam washers help eliminate this risk by providing a controlled conductive pathway for charge dissipation.
They are widely used for packaging, storage, and transportation of delicate electrical components, offering superior protection against electrostatic discharge, vibration, and impact.
Beyond static protection, conductive foam washers also:
- Reduce unwanted noise and vibration
- Fill gaps and irregular surfaces.
- Provide insulation and cushioning.
- Offer moisture and dust sealing properties.
Their closed-cell structure prevents air, gas, and liquid penetration, while their lightweight, flexible nature makes them easy to handle and install.
Benefits Of Using Conductive Polyethylene Foam Washers
- Permanent and consistent ESD protection
- Ideal for repeat use in packaging, handling, and assembly applications
- Provides controlled dissipation of static charge
- Lightweight yet durable with excellent cushioning properties
- Reduces the risk of component damage and costly replacements
- Moisture-resistant closed-cell structure for long-term reliability
These benefits make conductive polyethylene foam washers an essential component in any environment where static safety and performance are priorities.
Advantage Of Using Conductive Polyethylene Foam Washers
Conductive PE foam washers combine durability, flexibility, and conductivity, offering an ideal balance of physical and electrical performance. Key advantages include:
- High tear strength and impact absorption
- Vibration damping and shock resistance
- Excellent resistance to water, grease, solvents, and chemicals
- Operating temperature range up to +90°C
- Odourless, non-toxic, and resistant to mould or bacterial growth
- Permanent conductivity — unaffected by humidity or ageing
Since conductive polyethylene is supplied in block form, it can easily be split or laminated to achieve non-standard thicknesses, ensuring precise and cost-effective manufacturing.
Common applications include medical devices, handheld electronics, LED displays, telecommunications equipment, and many other environments where static control and reliability are essential.
