EPP lightweight construction in caravans

EPP moulded parts / cellular foam solutions for caravans and motorhomes

Lightweight construction

There is no doubt that the use of particle foam represents a forward-looking approach to the construction of vehicles, caravans and motorhomes. What makes it particularly interesting is not only the considerable freedom it affords in terms of design, but also its high structural strength combined with very low weight, its good resilience and its reliability across a wide range of temperatures. Lightweight construction is the trend, as reducing the vehicle’s weight ensures compliance with the 3.5-tonne limit for a Category B driving licence.

Well insulated

Vehicle insulation using EPP moulded parts. Here too, open-cell foam can make a significant contribution: to energy management thanks to its excellent thermal insulation properties, as well as through effective sound absorption. The material is also increasingly being used in visible areas. Laser structuring can enhance EPP components both visually and technically – providing additional functions and greater individuality. This results in high-quality surfaces that blend harmoniously into the caravan’s design whilst proving robust in use.

Fully protected

Automotive moulded parts made from EPP particle foam are ideally suited to a wide range of applications thanks to their special properties. For example, particle foam inserts have an excellent ability to absorb energy under dynamic loads. Impact absorbers in the floor assembly, headliner and side panelling, steering column, headrests and bumpers primarily serve to provide passive protection for occupants and the chassis. In electric vehicles, the protection of battery systems is particularly important.

Advantages of EPP in lightweight construction

Advantages of EPP in lightweight construction

EPP – Expanded polypropylene is a soft-elastic to hard, closed-cell thermoplastic particle foam. Thanks to EPP’s outstanding properties, combined with its high design flexibility, the material is used successfully in many industries, including caravans, automotive, HVAC, sport/leisure, construction and packaging.

  • High structural strength
  • Extremely low weight
  • High energy absorption
  • High resilience in EPP
  • 100% recyclable
  • Good chemical resistance 
  • Good sound insulation
  • Excellent thermal insulation, e.g. for e-mobility
  • Great design flexibility

Why use EPP foam in a caravan?

EPP combines lightweight construction with high rigidity and compressive strength, thereby making a significant contribution to weight reduction and energy efficiency. At the same time, the material offers good thermal and acoustic insulation, high comfort and safety thanks to its excellent impact resistance and resilience, whilst also being resistant to moisture and chemicals such as oils and greases. Thanks to the great freedom of form and design, even complex geometries can be realised, and the design, density and colour can be fully customised.

Laser textures – aesthetics and functionality with EPP

Laser texturing elevates EPP components to a PREMIUM LEVEL, both visually and technically, offering greater functionality and individuality. The result is high-quality surfaces that blend seamlessly into the design of cars, motorhomes or caravans, whilst proving to be robust in use.

  • PREMIUM LOOK High-quality and modern visible surfaces.
  • DESIGN FREEDOM From fine grain patterns, e.g. leather-like finishes, to distinctive graphic designs.
  • TEXTURE A noticeably pleasant feel and a high-quality impression.
  • WATER-REPELLENT SURFACE Through targeted laser structuring, EPP particles on the surface can be fused together to form a closed, water-repellent layer.
  • DURABILITY Permanently resistant to abrasion and wear, without additional coatings. The functionality is permanently retained.

Questions and Answers – Lightweight Caravans with EPP

What is EPP?

EPP – Expanded polypropylene is a soft-elastic to hard, closed-cell thermoplastic particle foam. Thanks to EPP’s outstanding properties, combined with its high degree of design flexibility, the material is used successfully in many industries, including caravans, automotive, HVAC, sports and leisure, construction and packaging.

EPP is an attractive material for lightweight caravan construction because it combines low weight with high rigidity, compressive strength and good insulation properties. As a result, EPP can help reduce weight and enable functional component design within the vehicle. This helps manufacturers to better comply with the 3.5-tonne limit for vehicles that can be driven with a Category B driving licence.

EPP combines lightweight construction with high rigidity and compressive strength, thereby contributing to weight reduction and energy efficiency. At the same time, the material offers good thermal and acoustic insulation, as well as impact resistance, resilience and resistance to moisture and chemicals, such as oils and greases. Thanks to the high degree of design freedom, even complex geometries and custom designs, densities and colours can be achieved.

Typical applications include tank insulation with access hatches, footrests, headliner insulation, trim panels, tool holders, wheel arch liners, furniture components, storage trays, sun visors, headrests, crash pads, bumpers and floor panels. EPP is therefore suitable for a wide range of functional and structural components in caravans.

Yes. EPP is increasingly being used in visible applications as well. Laser structuring can enhance surfaces both visually and to the touch. This results in high-quality visible surfaces with greater design freedom for interior and functional components.

EPP cellular foam is moisture-resistant, dimensionally stable and also offers good chemical resistance, for example to oils and fats. This makes the material suitable for many applications in caravans where durability, hygiene and robust material properties are required.

Laser texturing does more than just enhance the appearance of EPP components. It can also create a sealed, water-repellent surface. Furthermore, the laser texturing can improve abrasion resistance.

Yes. EPP is 100% recyclable. This makes the material an attractive option for caravan designs where, in addition to functionality and weight, recyclability is also a key consideration.

Schaumaplast works closely with customers to develop bespoke EPP solutions for caravan and motorhome applications.
