What is Polyethylene Foam?

Plastazote is a polyethylene foam product. Polyethylene foam is more commonly referred to as closed cell foam. This type of foam consists of microscopic sealed cells which interlock and prevent water or air from passing through it. It is a rigid and water-resistant foam type which makes it perfect for the likes of shock absorption and thermal insulation.

How Plastazote Foam is Manufactured

Being a polyethylene foam product, Plastazote is initially created in the same manner. Crude oil is fractionally distilled to create Naphtha which can then be used in the formation of plastics and other chemicals. By further processing Naphtha, polyethylene can be created.

Plastazote foam is unique in that it contains an abundance of nitrogen filled cells. Nitrogen is blown into polyethylene foam before its initial expansion, which gives Plastazote its unique properties. Unlike many other foam types, it is tough yet flexible. Because air cannot pass freely through it, Plastazote quickly bounces back to its original shape when compressed.

The Benefits of Plastazote Foam

Due to its unique structure and chemical composition, this foam offers a wide array of benefits. It can be easily cut and shaped making it ideal for case inserts. It can also be bonded to a wide variety of materials including metal, wood, fabrics and other Plastazote sheets to name a few.

This closed cell polyethylene foam is also lightweight, odourless and non-toxic. Because it does not absorb or allow water to freely pass through, it is also extremely buoyant. This makes it an excellent choice for use in water as a flotation aid; as such, it is commonly used in swimming pools.

Swimming is not the only sport which benefits from this product, however. Due to its high shock absorption capabilities, Plastazote is commonly used within sports protection equipment. It can line helmets and be used as a liner in body padding. Other sports-related products it can be found within include gym mats, surfboards, and shoe insoles.

Plastazote is also highly resistant to many chemicals including most acids, alkalis, solvents, and oils. It can be easily disinfected and cleaned, making it ideal for use in some healthcare equipment such as surgical splints, orthopaedic shoes, and mobility equipment.

Breakdown of Plastazote Foam Benefits –
  • Durable and lightweight.
  • High chemical resistance.
  • Easily wiped clean and disinfected.
  • Water resistant and buoyant.
  • Good thermal insulation.
  • Non-toxic.
  • High shock absorption.
  • Easy to cut and shape.
  • Odourless.
  • Weatherproof and good ultraviolet stability.
