Evazote Foam Strip
Evazote Foam Strip
Advanced Seals & Gaskets Ltd are leading manufacturers of Evazote foam cut strips. 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 strips made to order. 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 many other materials. 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 strips in lengths of up to 100 meters.
Evazote foam strips, gasket tapes or sealing strips or foam tapes as they are commonly know, are all made to order, manufactured using state of the art machinery including band saws, strippers, log cutters and even presses depending upon the size and quantity required - for very small strips in high volume runs, a kiss-cut option may also be available for faster production and time efficiency for the end user. In-house production allows us to closely oversee the whole production process to ensure that we consistently produce high quality, competitively priced Evazote strips Our on-site laminating service enables us to supply Evazote foam strips in choice of finishes including plain or coated on one of both faces with a range of self-adhesives, foils or even laminated to other materials.

What are Evazote Foam Strips?
Evazote foam strips are pieces of material cut to a specific length as requested by our customers, alternatively they can be taken as continuous rolls or coils to be cut down to the required length by the end user. These Evazote foam tapes are often used in a similar way to a gasket placed between two surfaces to create a seal or provide cushioning and insulation. 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 strips 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 Strips?
Evazote foam strips can be used to fill gap and irregularities between uneven surfaces, provide a solution to unwanted rattles, noise and vibration, to seal against dust, gas and liquids or to be used as a cushion or spacer between moving parts reducing friction and damage caused by impact. Evazote strips are available in different densities and colours, and can be cut from sheets or rolls of material depending upon the length of strip required. Evazote strips are tough and flexible, they have a closed cell structure therefore impenetrable to air and moisture, meaning they will not absorb liquids or allow them to pass through, also resistant to many chemicals. Although softer than some other plastazote and polyethylene foam strips, those manufactured using Evazote are more resilient and durable enabling them to absorb impact and pressure without deteriorating or tearing.
Evazote foam strips and tapes can be found widely used within the building and construction industries where they are used to create seals, gasket tapes, and impact protection. Evazote foam strips can easily be compressed, which is a requirement when used as a gasket for it 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.

- Non-toxic and low odour
Advantages of Using Evazote Foam Strips
Evazote foam strips or Evazote tapes can be quicky and easily manufactured from stock. As the raw materials are manufactured in block form, it allows us the option to produce long strips from rolls and shorter strips from sheets in the most cost effective way with minimal waste. Evazote foams are popular for the production of tapes and cut strips 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 strips offer a wide functioning temperature range, maintaining its properties in temperatures as low as -70°C to as high as 100°C. Evazote strips can be manufactured by block conversion which include processes such as splitting, pressing, die cutting and log cutting, as well as being moulded into a specific profile such as where a textured surface is required. 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.
