EVA Polyethylene Foam Washers

At our onsite storage and conversion facility, Advanced Seals & Gaskets Ltd collaborates with reputable material manufacturers and suppliers, allowing us to offer a diverse range of foam washers in various grades, densities, and colors. Among the materials we utilize, one noteworthy option is Expanded Closed Cell Cross-Linked EVA Polyethylene foam, often referred to as 'EVA block foam.'

EVA Polyethylene foams, closely resembling standard Polyethylene, stand out due to their cross-linked nature, offering superior strength and resilience thanks to their ethylene vinyl acetate (EVA) content. This material results from a copolymerization reaction between vinyl acetate and ethylene, serving as a versatile alternative to materials like PVC foam.

Typically, EVA Polyethylene foam comes in block or 'bun' form, allowing us to cut washers as thin as 1.5mm. Our EVA Polyethylene foam washers are entirely bespoke, tailored to order based on dimensions, samples, or drawings provided by our customers, ensuring a precise fit for the intended application. If necessary, we can even produce small sample runs.

The production process for EVA Polyethylene foam washers hinges on their size and quantity. Our production team selects the appropriate machinery from our arsenal of atoms, autos, traveling head presses, and kiss cut pressing machines. For larger or thicker washers, we can program our CNC (oscillating knife) for efficient production, reducing lead times.

We maintain stock of EVA PE foam in various grades, colors, and densities. These foams offer further customization potential as they can be laminated with other materials or coated with a self-adhesive backing before being cut into washers, catering to the unique requirements of our customers.

    What are EVA Polyethylene Foam Washers?

    EVA Polyethylene foam washers comprise an Outer Diameter (OD), Internal Diameter (ID), and thickness, cut from sheet or roll materials. Their versatility allows them to serve various purposes: creating level surfaces, acting as spacers, or distributing pressure between nuts and bolts to establish seals.

    Comparable to other polyethylene foams, EVA Polyethylenes are produced in block form, with different densities and colors customized for specific applications. As a member of the Thermoplastic foam family, EVA PE foam showcases a uniform, closed-cell structure that renders it impervious to liquids, gases, and particles, ensuring effective sealing.

    Through the cross-linking process, the material gains strength, boosting compression strength, resistance to compression set, thermal stability, and tensile strength. EVA 30kg Polyethylene follows a manufacturing process similar to standard PE foams but includes EV, imparting a distinctive 'rubbery/spongy' texture and enhanced recovery. These washers prove highly suitable for demanding applications.

    Why use EVA Polyethylene Foam Washers?

    EVA Polyethylene foam washers come in diverse densities and colors, cut from sheets or rolls based on cost-effectiveness and quantity. These washers exhibit resilience and a closed, fine cell structure, making them impermeable to air, moisture, and chemicals.

    While softer than some counterparts, EVA Polyethylene variants offer remarkable durability, absorbing impact and pressure without tearing. Commonly employed in the construction industry, these washers serve multiple functions: creating seals, filling gaps, dampening noise and vibrations, and protecting against air, gas, dust, and liquids. They also minimize friction and safeguard equipment.

    Effective washers require compressibility to form pressure and airtight seals, a crucial requirement for gaskets, which EVA Foam washers fulfill. Additionally, EVA Polyethylene foam stands out for its resistance to wear, tear, Ozone, UV, and a broad working temperature range (-40°C to +80°C).

    The material's mechanical properties further contribute to noise and vibration control, making it suitable for thermal insulation. In summary, EVA Polyethylene foam washers offer a versatile solution for a wide range of applications.
