EVA foam – short for Ethylene Vinyl Acetate – is a soft, flexible, and durable material that’s widely used in healthcare, orthotics, sports, education, and beyond. Known for its shock-absorbing and cushioning qualities, EVA foam strikes a balance between firmness and comfort. It’s often used to make insoles, orthotic devices, protective padding, and therapeutic supports.

Why is EVA foam so popular in clinical and therapy settings?

It’s lightweight, water-resistant, easy to cut and shape, and available in a range of densities. This makes it ideal for custom-made orthoses or footwear modifications where both performance and patient comfort matter. Podiatrists, physiotherapists, and orthotists value its ability to absorb impact and reduce pressure – especially under high-load areas like the heel or forefoot.

In the sensory and education market, EVA foam’s softness and bright colours make it a favourite for safe play mats, seating supports and sensory integration tools. It’s non-toxic, easy to clean and gentle on skin - making it suitable for children or vulnerable users.

In manufacturing and design, EVA foam is valued for its excellent formability – it can be thermo-moulded, sanded, glued or layered for bespoke designs. At Algeos, we stock EVA sheets in various thicknesses, colours and shore hardness levels, catering to everything from clinical orthotics to creative and industrial uses.

Whether you’re designing custom foot orthoses, building supportive therapy equipment or looking for a lightweight padding material, EVA foam offers a practical and cost-effective solution.

EVA foam is a reliable, versatile material that serves a huge range of industries. With excellent shock absorption, comfort and adaptability, it remains one of the go-to materials for professionals in healthcare, education and design. Here are some of the most common questions we get about EVA.

EVA Foam Sheet

Are EVA Foam Mats Waterproof?

Yes, foam mats made from EVA are waterproof. The closed-cell structure of EVA prevents water and moisture from being absorbed, making it an ideal material for mats used in environments where they may be exposed to water, such as bathrooms, kitchens, or outdoor areas. This waterproof property also makes EVA easy to clean and maintain.

Can EVA Foam Be Laser Cut?

EVA foam can be laser cut, but there are some considerations to keep in mind. Laser cutting can produce precise and intricate designs on EVA foam, but it also generates fumes, so proper ventilation is necessary. Additionally, the thickness of the foam and the power of the laser will affect the quality of the cut. Testing on a small piece before proceeding with a full project is recommended.

Can EVA Be Recycled?

EVA can be recycled, but the process is not as straightforward as with other materials like paper or metal. Recycling EVA foam typically requires specialized facilities that can handle the material's specific properties. In some cases, it may be ground down and reused in the production of new foam products. However, not all recycling centers accept EVA foam, so local recycling options should be checked.

Can You Cut EVA Foam with a Hot Wire?

Yes, EVA foam can be cut with a hot wire cutter. A hot wire cutter allows for smooth and precise cuts, especially for thicker foam. This method is popular in crafting and cosplay for shaping foam pieces. However, cutting with a hot wire can produce fumes, so it's important to work in a well-ventilated area and use proper safety equipment, such as masks and gloves.

Laser Cut EVA

Can You Cut EVA Foam with a Laser?

Yes, EVA foam can be cut with a laser cutter. Laser cutting is an effective method for creating intricate designs and precise edges on EVA foam. However, like other methods involving heat, laser cutting EVA foam generates fumes that can be harmful if inhaled, so proper ventilation is essential. Additionally, the settings of the laser cutter need to be adjusted based on the thickness of the foam.

Can You Dye EVA Foam?

Dyeing EVA foam is possible, but it can be challenging. EVA foam does not absorb liquid dyes easily due to its closed-cell structure. However, you can use certain methods such as spray painting, using fabric dye, or applying a thin layer of acrylic paint mixed with water. It’s important to note that the surface finish and flexibility of the foam may be affected by the dyeing process.

Can You Paint EVA Foam?

Yes, you can paint EVA foam. It’s common to use acrylic paints for this purpose, as they adhere well to the foam’s surface. Before painting, it’s recommended to prime the foam with a flexible primer or a mixture of PVA glue and water to create a smoother surface. After priming, you can apply multiple layers of paint for the desired coverage. Sealing the painted foam with a clear coat can protect the finish.

Can You Sand EVA?

EVA can be sanded to smooth edges or create specific shapes. Sanding is particularly useful in crafting and cosplay to refine the surface after cutting. Using a fine-grit sandpaper is recommended to avoid tearing the foam. Sanding EVA foam can create dust, so wearing a mask and working in a well-ventilated area is important. Sanding can also prepare the surface for painting or gluing.

Can You Spray Paint EVA Foam?

Yes, EVA foam can be spray painted. Before spray painting, it’s best to prime the foam with a flexible primer to help the paint adhere better. Use multiple light coats of spray paint rather than one heavy coat to avoid oversaturation, which can cause the foam to warp. After the paint has dried, a clear sealant can be applied to protect the finish.

Can You Wash EVA Foam?

EVA foam can be washed, especially if it’s used in items like mats or costumes that may get dirty. Washing should be done with mild soap and water; avoid using harsh chemicals that could degrade the foam. After washing, the foam should be thoroughly dried before use. For large foam items, wiping them down with a damp cloth is often sufficient.

Do EVA Foam Sheets Absorb Sound?

EVA foam has some sound-absorbing properties due to its closed-cell structure, but it is not as effective as specialized acoustic foam. It can reduce noise by dampening sound vibrations, which makes it useful in certain applications, such as reducing noise in a room or softening the impact of footsteps. However, for serious soundproofing, other materials designed specifically for acoustics are more effective.

EVA for Crafts

Does EVA Absorb Water?

EVA does not absorb water due to its closed-cell structure, which makes it waterproof. This property is one of the reasons EVA foam is widely used in applications where moisture resistance is important, such as in water sports equipment, outdoor mats, and certain types of footwear. Its resistance to water also makes it easy to clean and maintain.

Does Conduct Electricity?

EVA is a good electrical insulator and does not conduct electricity. This property makes it suitable for use in various electrical and electronic applications where insulation is required. EVA foam can be used as a protective layer around electrical components or as part of an anti-static mat, although other materials specifically designed for electrical insulation may be preferred in high-risk environments.

Does EVA Contain Latex?

EVA does not contain latex. It is made from Ethylene Vinyl Acetate, a synthetic material that is free from latex proteins. This makes EVA foam a safe option for individuals with latex allergies. Its latex-free nature contributes to its popularity in the medical and footwear industries, where avoiding allergic reactions is essential.

How Strong is EVA?

EVA is known for its strength and durability, particularly in terms of impact resistance and flexibility. While it is soft and lightweight, it can withstand considerable wear and tear, making it ideal for applications where cushioning and protection are required, such as in sports equipment, footwear, and orthotics. The foam's strength also makes it a popular choice in the crafting and cosplay communities.
