What is SPX?


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 and flexible. It has excellent shock absorption and cushioning properties. SPX also has a tremendous weight to strength ratio and has a high thermal resistance.
