EPP is a polypropylene foam consisting of expanded, mainly closed-cell foam particles. The EPP beads are filled with air and therefore particularly environmentally friendly(light weight). They guarantee a good joint tightness of the moulded parts and provide an excellent insulation and thermal insulation.

A high energy absorption（shock resistance）capacity combined with a very good recovery behaviour are characteristic properties of EPP in addition to the good chemical and temperature resistance. The low water absorption( water proof) due to the closed-cell structure and hydrophobic surface property, the easy cleaning of moulded parts, the good thermal insulation capacity as well as its environmental compatibility (= free of propellants and other chemical blowing agents) round off the property profile of EPP.

For the use as reusable packaging and reusable transport and insulation containers, the excellent material properties of EPP are used in an ideal form.

Processing

EPP is processed on automatic foaming machines which are designed for a steam chamber pressure of at least 5 bar. The foam particles are transported from a pressurized container via injectors into the mould. Since EPP does not contain any blowing agent, it is necessary to compress the foam particles in the mould. Welding of the EPP beads to a molded part is done by using water vapor as heat transfer medium. The demoulding is done by mechanical ejectors and/or compressed air. For dimensional stabilization, the molded parts must be tempered (= dried) at approx. 80°C after demolding.

Application areas

The specific product properties of EPP are innovative and unrivalled and make EPP a multifunctional material with almost unlimited design possibilities for a wide range of applications.

EPP proves itself in areas where strength at low weight, high stiffness or good thermal properties are required, such as

• Automobiles as energy-absorbing foam such as bumpers, side impact protection or for sun visors or neck supports
• As protective and reusable packaging for sensitive products
• Electronic engineering as well as heating, air conditioning and sanitary engineering as a multifunctional part with multiple uses (impact protection, thermal insulation)
• In safety relevant products such as child seats and bicycle helmets
• The toy industry or the design and furniture sector
• For the transport of temperature-sensitive foodstuffs from A to B
