Expanded Polystyrene

Expanded polystyrene (EPS) is produced from a mixture of about 90-95% polystyrene and 5-10% gaseous blowing agent, most commonly pentane. The solid plastic is expanded using steam and is injected in to an aluminum tool under high pressure. Whether white or coloured, EPS starts life the size of a grain of salt. Once the raw material has gone through the pre-expansion process the grain swells with air expanding up to 50 times its original size.

Key Benefits

100% Recyclable

Fully recyclable. Recycled material grades containing granulated end-of-life parts is available


Durable with high strength to weight ratio

Thermal Insulation

Outstanding thermal insulation for both hot and cold applications

Resource Efficient

Raw material expands to 50 times its size producing a moulding that is 98% air. Think of a balloon - little material with lots of air


Generates weight saving in components leading to fuel efficiencies across many modes of transport


Vibrant colours available for branding, improved aesthetics or colour coding purposes

Add a splash of colour

Not everything is black and white, it’s pink, green, orange and blue too! We manufacture raw EPS foam that can be pre-coloured or pigments can be introduced during the expansion process without any adverse effects on the performance or properties of the moulded product.

Consider injecting EPP and EPS parts with some colour for branding, product identification or to simply improve the final aesthetic and visual appeal.
