Correctly foamed polyethylene has a structure of small regular cells. Due to this factor it has a high heat and sound insulation capacity and excellent shock absorbing capability. The building-, packaging- and automotive industry and the producers of sports- and leisure articles are happy to utilise these excellent properties. PE foams can be produced in any colour desired. Children highly appreciate the colourful fun toys for swimming pools and three-dimensional puzzles. Their parents and grand parents are more charmed by the comfort of garden seat cushions and knee protectors.
