PLASTAZOTE® Foam Applications
Plastazote® Foam has a wide variety of commercial and industrial applications due to its toughness, durability and flexibility. Indeed, the inert qualities of Plastazote® (it is chemically resistant to most solvents, oils, alkalis and acids) and the fact that it can be washed, wiped clean and disinfected, have led to its widespread use in the healthcare market today. It can commonly be found in mobility equipment, medical supports and prosthetics, orthopaedic shoes, surgical splints and collars.
Plastazote®’s composition (it is a closed-cell polyethylene foam blown with nitrogen) also means that liquids are not absorbed. Combined with the fact that it is lightweight, buoyant, non-toxic, odourless and a very good thermal insulator, Plastazote® is the foam of choice for use in aquatic products such as swimming floats, life jackets, buoys, surfboards and boats.
Its qualities do not end there. Plastazote® can be bonded to other materials such as fabrics, wood, metal and foam, moulded at relatively low temperatures, and easily shaped and cut. It is also weatherproof with strong ultraviolet stability.
Additionally, even if Plastazote® Foam is compressed or squashed, it bounces back to its original shape. This ability to recover repeatedly from impacts means that it has come to be frequently used as body protection and helmet lining for most contact and extreme sports.
Other diverse, yet common applications of Plastazote® include: gaskets and seals; museum and archiving storage; tool trays and storage; sound and pipe insulation; sleeping, gym and exercise mats; various product packaging and displays; shoe insoles; stage props and theatre/film set designs.

What is Plastazote®?
Plastazote® is the provided trade name for a specific close cell compound that is cross-linked to Polyethylene foam. This compound is part of the Azote family, along with Evazote® and Supazote®. It is manufactured in the United Kingdom at Zotefoam PLC and has been for many years now.
Plastazote® is initially manufactured by using a specific and bespoke nitrogen expansion process that results in the Polyethylene foam becoming entirely passive. This characteristic opened the door to its use in specific markets, such as healthcare where it is used in the production of braces, supports and artificial limbs.
Due to being totally inert and acid free, Plastazote® also provides an ideal solution when it comes to packaging. It is often used as packing foam in archival boxes and the like. It offers a secure fit and brilliant protection to certain valuable items that could potentially be subject to damage.
Where is Plastazote® used?
Plastazote® foams are often used in a wide range of different industries. Due to its durability, multipurposeness and ability to be combined with other compounds, it fits the bill for a number of different products, in a variety of different industries, such as:
- Sports (for protective clothing/padding)
- Healthcare (for artificial limbs etc.)
- Automotive (bespoke and thermoformed parts)
- Industrial (for certain gaskets and seals)
