What is SPX Polyethylene Foam?

Expanded polyethylene (aka SPX foam) refers to foams made from polyethylene. It is manufactured from plastic pellets, and a blowing agent is used to expand the material in a mould heated by steam. It is primarily used in material for packaging goods as it is lightweight, resilient and flexible. It has excellent shock absorption and cushioning properties. SPX expanded polyethylene sheets also have a tremendous weight-to-strength ratio and high thermal resistance. 

Advantages of SPX Foam

  • The product range is free from CFCs and HCFCs.
  • Expanded polyethylene is resistant to dilute alkalis and acids, some oils, and weathering. It is also non-toxic and has excellent absorption characteristics. 
  • Our high-quality closed cell foam is resistant to water, which makes it an excellent buoyancy solution
  • Fire retardant and rough cell materials are also available. 
  • Expanded PE foam is available in a variety of densities and colours
