Evazote Foam Gaskets
Advanced Seals & Gaskets Ltd are leading converters of Evazote foam products. Our extensive storage facilities allows us to stock Evazote on blocks, sheets and rolls in a range of densities and colours all ready to be cut into bespoke gaskets. Evazote® Foams are closed cell cross-linked ethylene copolymer foams, and look almost identical to Plastazote variants, however Evazote foams are stronger and more resilient due to the EVA (ethylene vinyl acetate) added to the raw compound.
Evazote or EVA foams are produced by a copolymerization reaction between vinyl acetate and ethylene, resulting in a versatile material which can be used as an alternative to other materials such as PVC foam. As with other polyethylene foams, Evazote foams manufactured in block form which can be split down into sheets of various thicknesses starting from as little as 1.5mm, or rolls - made by joining blocks of material together prior to splitting them, both of which can be used to further convert into cut gaskets.
As our Evazote foam gaskets are produced in-house on state of the art machinery, we can manufacture bespoke items to match our customers samples or drawings, from a simple rectangular picture frame gasket, to a more complex profile with cut-outs and notches - we can offer a solution. Whether it’s a small sample batch or a multi-thousand run, we have a machine to quickly and accurately produce perfectly formed gaskets in a range of sizes, these include a number of presses, CNC and kiss cut machines. Our Evazote foam gaskets can be produced plain or with a choice of finishes including foils, self adhesives or laminated to other materials. Depending on the size and quantity of the gasket, they can be supplied as loosely packed parts, or kiss-cut on a roll for quick and efficient use.

What are Evazote Foam Gaskets?
EV30 or Evazote foam gaskets can take the form of a strip or pad, but are generally an intricately cut shaped piece of material placed between two surfaces to create a low pressure seal preventing the leakage of liquids or gas and to seal against the intrusion of dust and debris when under compression. A gasket is also a term used in the industry to describe a pad or disc that contains details such as holes and cut outs using a CNC machine or die cutting. Like other polyethylene foams, Evazote is manufactured in block or ‘bun’ form, in a range of densities and colours for use in different applications.
This foam is manufactured under high pressure, high temperature and using Nitrogen expansion to create a high quality material with uniform cell size and is water repellent. Evazote is a closed cell foam, manufactured using ethylene vinyl acetate, which creates a ‘rubbery/spongy’ feel. Evazote foam gaskets are available in 2 grades, but at different densities, an EV and VA, the difference between the two being the proportional makeup of the ethylene vinyl acetate copolymer, EV has a higher VA content and a VA grade which has a lower VA content.
Why use Evazote Polyethylene Foam Gaskets?
Evazote foam gaskets are available in different density and colours, cut from sheets or rolls of material depending upon the size and quantity of gaskets required. Evazote gaskets are tough and flexible, they have a closed cell structure meaning it is impenetrable to air and moisture, meaning it will not absorb liquids or allow them to pass through, also resistant to many chemicals. Although softer than some other plastazote and polyethylene foam gaskets, those manufactured using Evazote are more resilient and durable enabling them to absorb impact and pressure without deteriorating or tearing.
Evazote foam gaskets can be found widely used within the building and construction industries where they are used to create seals and expansion joints, they can also be used as shoe insoles and swimming floats or boat fenders. Evazote foam gaskets are used to fill gaps and irregularities between uneven surfaces, provide a solution to unwanted rattles, noise, vibrations, to seal against air, gas, dust and liquids, and can also be used to cushion between moving parts to reduce friction and damage to components and equipment. Evazote foam gaskets can easily be compressed, which is a requirement In order for a gasket to work effectively, as it needs to compress and fill the entire space to create a pressure and air tight protective seal Evazote foams offer vibration and impact absorption, resistances to chemicals and weather/environmental influences, thermal insulation and acoustical properties and buoyancy.

Advantages of Using Evazote Foam Gaskets
Evazote foams are popular for gasket production as the material offers users countless advantages, and is highly utilised in many industries and applications. Evazote foam is a man-made material, designed to suit a range of requirements offering features such as being odourless, lightweight, buoyant, non-toxic and offer resistance to many oils, solvents, acids, alkalis, it’s closed cell surface and structure does not allow the absorption of liquids and is easy to keep clean, as well as being weatherproof and UV stable.
Evazote foams are usually the preferred choice for the production of gaskets which require excellent recovery from repetitive impact and compression. Evazote gaskets offer a wide functioning temperature range, maintaining its properties in temperatures as low as -70°C to as high as 100°C. components including gaskets can be manufactured by block conversion which include processes such as splitting, pressing, die cutting, routering and log cutting, as well as being moulded into a specific profile. The cost effectiveness, ease of machining and converting this material combined with the flexibility of being also able to buy moulded parts means Evazote foams can be taken and used in a range of applications and industries.
