EVA Polyethylene Foam Gasket

EVA Polyethylene Foam Gaskets

Advanced Seals & Gaskets Ltd, a leading converter of Polyethylene foam gaskets, offers various grades, densities, and colors, including Expanded Closed Cell Cross Linked EVA Polyethylene foams at 30kg and 45kg densities. These versatile Polyethylene foams, also known as Block Foam, EVA Block Foam, or EVA PE Foam, are exceptionally strong and resilient due to their ethylene vinyl acetate content.

EVA Polyethylene foam is synthesized through copolymerization of vinyl acetate and ethylene. It serves as a viable alternative to materials like PVC and Polyurethane foams. In block or 'bun' form, it's available in various thicknesses, starting as thin as 1.5mm, suitable for gasket production. Our in-house manufacturing utilizes cutting-edge machinery to create bespoke gaskets, matching customer samples or drawings, from simple rectangular frames to intricate profiles with cut-outs and notches.

Our equipment includes presses, CNC, and kiss-cut machines, ensuring rapid and precise gasket production in diverse sizes. These EVA Polyethylene foam gaskets can be delivered plain or with finishes like foils, self-adhesives, or lamination with other materials. Depending on size and quantity, they can be supplied as loosely packed parts or kiss-cut on rolls for efficient usage.

    What are EVA Polyethylene Foam Gaskets?

    EVA PE foam gaskets, whether in strip or pad form, serve as intricately shaped materials to establish low-pressure seals. They prevent liquid or gas leakage and block dust and debris intrusion when compressed.

    These gaskets may also feature intricate details like holes and cutouts, created using CNC machines or die-cutting processes. EVA PE foam, a crosslinked Polyethylene foam, undergoes a manufacturing process called crosslinking, rendering it resistant to various substances, including chemicals.

    Ethylene-vinyl acetate (EVA) is a co-polymer of ethylene and vinyl acetate, known for its fine closed cell structure, impermeable to air and liquids. Crosslinking, combined with EVA additives, results in a lighter, more elastic material with superior stretching and compression recovery. It also boasts a smoother appearance compared to standard PE foam.

    Why use EVA Polyethylene Foam Gaskets?

    EVA PE foam gaskets, available in 30kg or 45kg densities and various colors, are crafted from sheets or rolls based on gasket size and quantity needs. Ethylene-vinyl acetate (EVA) Polyethylene, boasting a fine cell structure, renders these gaskets impervious to air and liquids, preventing moisture passage and absorption.

    While softer than some polyethylene foam gaskets, EVA Polyethylene variants exhibit exceptional resilience and durability, enduring impacts and pressure without degradation.

    Widely employed in the building and construction sectors, EVA PE foam gaskets serve to create seals and expansion joints. They can also be fashioned into shoe insoles, swimming floats, or boat fenders. EVA Polyethylene foam gaskets prove invaluable for filling gaps and addressing uneven surface irregularities.

    These versatile gaskets tackle issues such as unwanted rattles, noise, vibrations, and they effectively seal against air, gas, dust, and liquids. Furthermore, they cushion moving parts, reducing friction and preventing damage to components and equipment.

    The compressibility of EVA PE Foam gaskets is essential for their effectiveness. They must compress and occupy the entire space to establish a pressure-tight and airtight protective seal.
