Evazote Foam Sheet
Advanced Seals & Gaskets Ltd’s extensive storage facilities allow us to stock Evazote on blocks in a range of densities and colours, all ready to be split into sheets. Evazote® Foams are closed-cell, cross-linked ethylene copolymer foams that 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.
EVA foams are produced by copolymerizing vinyl acetate and ethylene, yielding a material that can be used as a PVC foam substitute. As with other polyethylene foams, Evazote foams are manufactured in block form, which can be split down into sheets of various thicknesses starting from as little as 1.5mm and supplied 1 1-meter or 2-meter lengths. Alternatively, the blocks of Evazote can be joined and split down into rolls of 10 metres or more, which can then be cut down into the desired-sized sheet by the customer or end user as required.
As we offer in-house conversion and lamination services, we can not only split materials but also laminate layers together to produce non-standard thicknesses or composite sheets using layers of different materials, and bond them with adhesives or foil facings to one or both faces. All customisation is carried out with customer preferences in mind, ensuring a mindful approach and attention to detail in meeting client needs. Our facilities house a number of presses, log cutters, strippers, bandsaws, CNC machines, and coaters, which can be used to produce a range of Evarangeoam products, including gaskets, washers, strips, pads, and fabrications, all of which can be cut from sheets. We can also manufacture specific items tailored to your requirements, offering a wide range of custom-made components from Evazote foam.

What are Evazote Foam Sheets?
As with 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 and high temperature, using Ni-en expansion, to create a high-quality material with uniform cell size and is water-repellent. Erepellency is a closed-cell foam, manufactured using ethylene vinyl acetate, which creates a ‘rubbery/spongy' feel. Evazote foams are manufactured in 2-meter-long x 1-meter-wide blocks, which can be split into 2-foot blocks. These sheets can be taken whole or cut into finished, usable parts such as strips, gaskets, washers, or pads. Evazote foam sheets are available in 2 grades that differ only in density: VA, with a different ethylene-vinyl acetate copolymer composition. EV has a higher VA content and a VA grade, while the ch has an LA content.
Why use Evazote Polyethylene Foam Sheets?
Evazote foam sheets are available in different densities and colours. They are rigid and flexible, have a closed-cell structure that is impenetrable to air and moisture, meaning they will not absorb liquids or allow them to pass through, and are also resistant to many chemicals. Although softer than some other plastazote and polyethylene foam sheets, those manufactured using Evazote are more resilient and durable, enabling them to absorb impact and pressure without deteriorating or tearing.
Components cut from Evazote sheets are used in the building and construction industries to create spacers, seals, and fasteners. They can also be used to cut shoe insoles, swim fins or boat fenders. Evazote foams are used in applications to fill gaps and irregularities between uneven surfaces, provide a solution to unwanted rattles, noise, and vibrations, and seal against air, gas, dust, and liquids. They can also be used between moving parts to reduce friction and damage to components and equipment.
Evazote foam sheets can be easily compressed, which is a requirement for Forskets cut from them to work effectively, as they need to compress and fill the entire space to create a pressure and air-tight protective seal. Evazote foams offer vibration and impact absorption, resistance to chemicals and weather/environmental influences, thermal insulation, acoustical properties and buoyancy.
Different Grades of Evazote Foam Sheets Available
- EV30
- EV50
- EV45CN - Conductive Evazote

Applications and Uses of Evazote Foam Sheets
Evazote foam sheets are renowned for their versatility and are widely used across a variety of industries thanks to their unique characteristics. The closed-cell structure of Evazote foam provides excellent impact resistance, making it an ideal material for applications where durability and resilience are essential. In the sports and leisure sectors, Evazote foam is commonly used in products and equipment that require superior cushioning and support. Its non-toxic and odourless properties make it a safe choice for products that come into direct contact with users. At the same time, its buoyant nature makes it ideal for sports and leisure items.
In the construction industry, Evazote foam sheets are commonly used in construction joints and as a reliable material for helping improve efficiency and reduce noise. The foam’s adaptability allows it to be manufactured into rolls that can be cut and shaped to meet specific manufacturing requirements, making it a popular choice for custom applications. Whether you need a lightweight, resilient material for sports mats or a durable solution for construction insulation, Evazote foam sheets provide the combination of characteristics for a wide range of applications.
Specialised Uses of Evazote Foam Sheets
Evazote foam sheets are also available in specialised conductive grades, which combine the general properties of the foam with reduced volume resistivity. These conductive grades are particularly valuable in industries that require the safe storage, protection, and transport of sensitive electronic components and devices, as well as for electromagnetic compatibility (EMC) shielding. The higher VA content in specific Evazote foam sheets enhances their resistance to solvents, oils, acids, and alkalis, making them suitable for demanding environments where chemical resistance is crucial.
The elastic and resistant characteristics of Evazote foam make it an ideal material for applications that demand both flexibility and toughness. Whether you need a material that can withstand harsh chemicals or one that offers reliable protection for electronic equipment, Evazote foam’s range of conductive grades and high-VA-content provides the flexibility and performance required by modern industries.
Handling and Storage of Evazote Foam Sheets
Proper handling and storage of Evazote foam sheets are essential to maintain their durability and performance. It is vital to keep Evazote foam away from heat sources and open flames, as exposure to high temperatures can damage the material. Store the foam sheets in a dry, well-ventilated area, away from direct sunlight and moisture, to preserve their integrity. When handling Evazote foam, avoid excessive friction and contact with other materials that could cause abrasion or surface damage.
Evazote foam sheets are easy to cut and shape using standard tools, enabling easy customisation to suit a variety of product requirements. Customers can select from a wide range of densities, colours, and sizes to match their specific needs, with the black stablack making it easy to identify and distinguish from other materials. The resilient and durable nature of Evazote foam ensures it remains reliable for industries seeking a material that is both easy to handle and store, while providing long-lasting performance across a wide range of applications.

Advantages of Using Evazote Foam Sheets
Sheets of Evazote foams are popular amongst our customers and can be taken in full or used to convert into finished components. The material offers users countless advantages and is widely used across industries and applications. Evazote foam is an artificial 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 components that require excellent recovery from repetitive impact and compression, such as gloves, knee pads, camping mats, and floor underlayment. Evazotms offer a wide operating temperature range, maintaining their properties from -70°C to 100°C.
Evazote sheets can be converted into finished products such as gaskets, seals, pads or washers, which can be manufactured using processes such as splitting, pressing, die cutting, routering and log cutting, as well as being moulded into a specific profile. The cost-effectiveness of this material, combined with its flexibility as moulded parts, means Evazote foams can be used across applications and industries.
