Epoxy Glass Washers

At ASG, we excel in manufacturing washers from a diverse selection of materials, including those designed for electrical insulation like Epoxy Glass. Epoxy Glass materials are distinguished by their green coloration, which may vary in shade depending on the grade. They are available in sheet or rod forms with various thicknesses and sizes that can be easily cut down to produce washers.

To ensure precision and reliability, we prioritize not only material selection but also the quality of the cut. Our in-house manufacturing team meticulously follows customer specifications, including details such as the Outer Diameter (OD), Internal Diameter (ID), and thickness, ensuring an exact match. Our skilled workforce, coupled with state-of-the-art machinery, including presses, saws, and CNC machines, enables us to produce Epoxy Glass washers in a wide range of sizes and quantities.

    What are Epoxy Glass Washers?

    The Epoxy glass washers, fabricated from Epoxy Glass raw material, act as flattened rings to reduce friction and enhance stability, primarily serving as insulators. Epoxy Glass, a composite material with a distinct green hue, is created by compressing layers of fiberglass and saturating them with epoxy resin, resulting in a robust and rigid sheet or tube product.

    Epoxy Glass exhibits hardness and brittleness, offering impressive mechanical strength and temperature resistance. Furthermore, it excels in providing excellent electrical insulation properties. This attribute enables it to regulate the flow of electric current by supporting electrical conductors while preventing the current from passing through.

    Why use Epoxy Glass Washers?

    Washers manufactured from Epoxy Glass play a vital safety role, acting as barriers to control electrical current flow, ensuring the safety of people and tools during installations, repairs, or appliance use. Additionally, electrical insulation materials like Epoxy Glass prevent electrical arcing, a phenomenon where current flows between conductors through the air, causing ongoing electrical discharge. These materials are renowned for their strength, durability, and machinability. They are available in a wide range of sheet thicknesses, from 0.2mm to 100mm. Precision-cutting processes such as drilling, routing, and CNC milling are employed to create custom-sized washers, while thinner sheets are converted using presses.
