How can a material that is so robust be as light as a feather! – A question we keep hearing in tones of incredulousness and amazement. The answer is simple, and is given away by the very term ‘particle foam’: More than 90 percent of expanded polypropylene is – air!
The resulting potential for lightweight construction makes the universal material one of the highest demanded materials in all industries wherever products have to be "trimmed down” for weight reasons. The most obvious places where this is an advantage are the wrapping, automotive and motorhome industries.
Car drivers can save costs by reducing the weight of their vehicle, and thereby do good for the environment. Recreational vehicle owners can do the same, and even benefit from some quite different and significant extra advantages: If a caravan weighs less than the “magic” limit of 3.5 tonnes, then substantial easements can be enjoyed on tolls and charges, speed limits, and parking and driver’s licence regulations.
