EVA Polyethylene Foam Sheet
EVA Polyethylene Foam Sheets, available in various grades, densities, and colors from Advanced Seals & Gaskets Ltd, encompass Expanded Closed Cell Cross-Linked EVA Polyethylene foams in 30kg and 45kg densities. These foams, often referred to as Block Foam, EVA Block Foam, or EVA PE Foam, are distinct due to their cross-linked nature, resulting from the ethylene vinyl acetate (EVA) content, making them stronger and more resilient compared to standard Polyethylene foam.
EVA Polyethylene foam material is created through a copolymerization reaction involving vinyl acetate and ethylene. This process yields a versatile material that can serve as an alternative to other materials like PVC and Polyurethane foams. EVA Polyethylene foam is stocked in block or 'bun' form, which can be conveniently converted into sheets of varying thicknesses starting from as little as 1.5mm, available in 1 meter or 2-meter lengths. Alternatively, the Evazote blocks can be joined and converted into rolls of 10 meters or more, which can then be cut into sheets of the desired size by the customer or end-user.
At ASG, we offer in-house conversion and lamination services, enabling us not only to split materials but also to laminate layers together, resulting in non-standard thicknesses or composite sheets composed of different materials. Additionally, we can apply self-adhesives or foil facings to one or both faces of the EVA foam. Our well-equipped facilities house an array of machinery, including presses, log cutters, strippers, bandsaws, CNC machines, and coaters, allowing us to manufacture a variety of EVA foam products, such as gaskets, washers, strips, pads, and fabrications, all expertly cut from EVA foam sheets.

What are EVA Polyethylene Foam Sheets?
EVA Polyethylene foam is produced as sizable blocks, measuring 2 meters in length and 1 meter in width. These blocks are then expertly split to create individual sheets. To achieve this, the master blocks undergo processing through one of our state-of-the-art splitters. These machines are equipped with blades that can be precisely adjusted to peel off the desired thickness of foam. The resulting foam sheets are then carefully rolled by our skilled operators, preparing them for further processes such as adhesive application or packaging for shipping.
The distinctive characteristic of EVA PE foam lies in its crosslinked nature. Crosslinking is a sophisticated manufacturing technique that imparts a heightened resistance to various substances, including chemicals. The foam's crosslinked structure results from the inclusion of Ethylene-vinyl acetate (EVA), a co-polymer derived from ethylene and vinyl acetate. This co-polymer introduces a very fine closed-cell structure that renders the foam impervious to both air and liquids.
This crosslinking process, in conjunction with the EVA additive, yields a foam material that is not only more resilient but also notably lighter and more elastic. EVA PE foam exhibits superior recovery from stretching and compression, providing a smoother and more refined appearance when compared to standard PE foam.
Why use EVA Polyethylene Foam Sheets?
EVA foam sheets are meticulously split from blocks of raw material, presenting customers with options in both 30kg and 45kg densities. These sheets come in an array of colors, adding to their versatility. Notably, EVA foam sheets boast a remarkable combination of toughness and flexibility.
One of the standout features of these sheets is their closed-cell structure, rendering them completely airtight and impervious to moisture. This impenetrability means that EVA foam sheets will neither absorb liquids nor permit them to pass through. In addition to this, EVA foam sheets showcase a high level of chemical resistance, making them an ideal choice in various demanding environments.
Although softer when compared to some other options like plastazote and polyethylene foam sheets, EVA foam sheets demonstrate exceptional resilience and durability. This unique combination allows them to absorb impact and pressure without showing signs of deterioration or tearing, offering valuable protective benefits.
Components crafted from EVA foam sheets find applications across a multitude of industries, with the building and construction sector being a prominent example. Here, these components are employed to craft spacers, seals, and expansion joints, thereby facilitating efficient construction processes. Additionally, EVA foam components serve in the creation of diverse products, including shoe insoles, swimming floats, and boat fenders. The range of applications extends to closing gaps and irregularities between surfaces, reducing unwanted rattles, dampening noise and vibrations, achieving air, gas, dust, and liquid-tight seals, and providing cushioning to minimize friction and damage between moving parts.
The compressibility of EVA foam sheets is a crucial attribute for seals and gaskets. These components must effectively compress to fill the available space, establishing a secure, pressure-tight seal. Evazote foams extend their utility to include vibration and impact absorption. They also offer resistance to chemicals and environmental influences, provide thermal insulation, demonstrate excellent acoustical properties, and even lend buoyancy when required.
In summary, EVA foam sheets and the components derived from them are versatile, highly durable, and provide a range of indispensable properties. These materials have found their place in numerous industries and applications, enhancing safety, performance, and functionality.
