Benefits of Plastazote Foam
Plastazote foam is known for its unmatched combination of durability, versatility, and safety — making it the ideal material for both specialist and everyday applications. Here’s why it stands out:
- Nitrogen-Blown Closed-Cell Foam - Resistant to water, air, and moisture — every cell acts like a tiny sealed bubble for maximum resilience.
- Lightweight Yet Tough - Easy to handle, yet strong enough to absorb shock and impact without breaking down.
- Non-Toxic & Odourless - Safe for medical, archival, and child-focused applications — with zero off-gassing or chemical smells.
- Waterproof & Buoyant - Naturally repels water and floats — perfect for marine use, flotation devices, or damp environments.
- Resistant to Chemicals - Holds up against oils, acids, alkalis, and solvents — ideal for workshops, labs, and industrial settings
- UV & Weather Resistant - Performs outdoors without degrading — trusted in construction, signage, and outdoor sports gear.
- Thermal & Acoustic Insulation - Offers excellent resistance to heat transfer and can help dampen sound in sensitive environments.
- Easy to Cut, Shape & Bond - Easy to cut and shape with blades, lasers , or die-cutting — and can be glued or thermoformed with ease.
- Repeated Recovery from Compression - Each nitrogen-filled cell rebounds back to shape — ideal for impact protection and reusable packaging.
Applications of Plastazote Foam
Thanks to its closed-cell structure, flexibility, and excellent resistance properties, Plastazote foam is used across a wide range of industries. Whether for protection, insulation, buoyancy, or display, Plastazotes applications are as varied as they are effective. Here are some of the most common uses:
- Museum & Archival Storage - Ideal for lining drawers, padding artefacts, and supporting fragile items in conservation-grade displays.
- Tool Control & Equipment Cases - Custom foam inserts for cases and drawers keep tools organised, protected, and impact-resistant.
- Medical Supports & Orthopaedics - Used in splints, braces, orthotic shoe inserts, and mobility aids due to its non-toxic, skin safe properties.
- Marine & Flotation Products - Buoyant and waterproof — perfect for pool noodles, buoyancy aids, floatation mats, and boat equipment.
- Props & Creative Industries - Used in stage, film, and cosplay for lightweight set designs, costumes, masks, and scenic structures.
- Packaging & Shock Protection - Custom-fit packaging for electronics, instruments, or fragile goods needing high-impact protection.
- Automotive & Aerospace - Anti-vibration pads, gaskets, sound dampening, and lightweight panel inserts.
- Sports & Recreation Gear - Found in yoga mats, gym flooring, helmet padding, and protective sportswear.
- Insulation & Sealing - Thermal barrier in construction, pipe insulation, or sealing gaps in foundations and sill plates. For the fire retardant variant of Plastazote foam please contact us for more information.
Plastazote Foam Sheets Frequently Asked Questions
How is Plastazote foam made?
Plastazote foam is made by heating polyethylene and expanding it with nitrogen gas under high pressure, forming uniform, closed cells. This process creates a lightweight, flexible, and chemically inert foam with excellent resilience and performance properties.
What is the meaning of 'closed-cell' foam?
When it comes to foam, there is a closed-cell and an open-cell. Soft sponges are typically open-cell, allowing water to be absorbed, which you can then squeeze out with your hand. Closed-cell is when there are walls around each cell. Water or other liquids cannot penetrate, and the foam is more rigid. Plastazote is a superior closed-cell foam.
Is Plastazote foam fire-retardant?
Just like most materials, plastazote foam is not fire-resistant. If you put a burning flame under it, it's likely to burn. However, it is only expected to be set on fire with flames if it's next to a very high temperature. Ask us about our fire-retardant version of plastazote today.
Is Plastazote foam toxic to humans?
Plastazote, in its solid form, is non-toxic. However, it is toxic during the manufacturing process when it's in a liquid form, and gases and fumes are likely to emanate from it. When it's not in its manufacturing and melted state, it's safe to use for all kinds of purposes, including for children, medical purposes, and everyday purposes.
Is Plastazote foam suitable as a sound insulator?
Plastazote foam can deaden sound and is ideal in studios and other places where you don't want the noise to escape. Plastazote's relatively rigid body with closed cells can absorb sound. However, you should also note that we sell acoustic foams designed to be sound insulators.
Can Plastazote foam be cut to size?
Absolutely. At eFoam, we offer a cut-to-size service for all Plastazote foam sheets, please contact us for your custom quote today! It can also be easily cut at home using a sharp knife, hot wire cutter, or laser cutter.
Can I use Plastazote foam as a lid or cover for my hot tub to keep the water warm?
Yes, due to its excellent thermal insulation properties, plastazote foam is the perfect material for hot tub lids or covers. For further information, see our 'Foam for Hot Tubs' blog article.
How do I stick Plastazote foam together to make a thicker piece?
To stick multiple sheets of Plastazote foam together, you can use a general-purpose adhesive spray glue, which we supply in a 500ml can. Alternatively, the sheets can be supplied with a convenient self-adhesive backing.
Is Plastazote foam waterproof?
Yes, Plastazote foam is completely waterproof. Its closed-cell structure prevents water absorption, making it ideal for marine applications, outdoor use, and damp environments.
Can Plastazote foam be used outdoors?
Yes. Plastazote is UV-resistant and weatherproof, making it suitable for long-term outdoor applications such as insulation, signage, or marine gear.
Is Plastazote foam recyclable?
Plastazote foam is made from polyethylene, which is recyclable in facilities that accept PE foams. Check with your local recycling service for specifics.
