If your application requires a foam with increased elasticity, shock absorption, and skin contact suitability, Evazote® is ideal.
Evazote® is a closed-cell, cross-linked ethylene copolymer foam. Although manufactured similarly to Plastazote®, using Zotefoam’s unique nitrogen-blown technique, the use of ethylene-vinyl acetate (EVA) instead of polyethylene results in significantly different characteristics. Evazote® offers increased elasticity and tear resistance, and provides the material with a rubbery, flexible feel. As a result, it is particularly suited to protective padding, orthopaedic footwear, industrial gaskets, and outdoor gear such as sleeping mats.
Polyformes is an official Zotefoam supplier. We can supply your business with Evazote® foam material (in the exact shape/size you need) or pre-finished products. Our experts can also provide free advice on the best foam material for your application.
Evazote® ethylene-vinyl acetate foam is available in four densities, ranging from 30 to 50kg/m³.
There are also two specific grades within the range. EV materials have a higher VA (vinyl acetate) content (typically around 18%), making them feel softer and rubbery. VA grades have lower VA content (approximately 9%).
Additionally, Evazote® is available as a conductive grade, combining the general properties with reduced volume resistivity. The conductive grade is suitable for a wide variety of applications, including the storage, protection, and transport of electronic components and devices, as well as EMC shielding.
For further details regarding individual material grades, please view the specific pages/datasheets.
Polyformes can split/skive, laminate and butt-weld Evazote® material to the specific dimensions you require. You can also select skin or cell finishes. MOQs may apply to certain size/material options.
Please get in touch with a member of our team to discuss your requirements.
The majority of Evazote® grades are suitable for conversion using the following processes:

Evazote® foam offers several beneficial properties, including:
Although Evazote® feels and exhibits properties similar to rubber, it is technically a foam. Manufacturing the material from ethylene and vinyl acetate, rather than polyethylene, which most foams use, provides the unique characteristics.
Although both are part of the Azote range of foams and are manufactured using a nitrogen-blown process, Plastazote® and Evazote® differ in the materials used to manufacture them. Plastazote is made from polyethylene, providing increased rigidity. Evazote® uses ethylene-vinyl acetate, which provides a softer, more elastic material.
Although EVA foams are generally considered non-toxic, some may release volatile organic compounds (VOCs) when heated or processed (e.g., cutting, sanding, etc.). However, because it uses nitrogen rather than chemicals during the manufacturing process, Evazote® is completely inert, odourless and hypoallergenic.
Evazote® is easy to process using standard foam conversion equipment. It is a thermoplastic material, meaning it becomes pliable when heated and retains its shape when cooled. It can be easily routed (CNC), heat moulded, water-jet cut, laminated and welded to create bespoke products (or material sizes) as required.
Evazote® is a highly durable, closed-cell, cross-linked ethylene copolymer foam material primarily made from an ethylene-vinyl acetate (EVA) copolymer. The manufacturer, Zotefoams, uses a unique high-pressure nitrogen gas-expansion process that links polymers at the molecular level into a solid, multi-directional protective structure.
The manufacturing process means that Evazote® offers improved softness, toughness, and cushioning compared to many standard chemically blown foams, while maintaining highly consistent cells and lower weight. It is also chemically inert, low-odour, non-toxic, and resistant to water, oils, and chemicals.
Evazote® is typically supplied in large, uniform blocks or “buns” (often around 2000mm x 1000mm with varying thicknesses). However, Polyformes can split, skive, and butt-weld Evazote® foam sheets to create specific sizes if required.
Polyformes is one of the longest-established foam suppliers and converters in the UK, having been supplying innovative, commercially successful foam solutions for well over 40 years.
