EPP Forum Bayreuth | Discover expanded polypropylene (2025)

Expanded polypropylene – EPP for short – is an innovative lightweight construction and design material. Numerous properties, including its feather-light weight, extreme robustness and durability, outstanding thermal insulation, countless design and formation possibilities as well as the fact that it is free from harmful substances, make EPP a material of the future – and the focus of the EPP Forum, which has set itself the goal of enabling the use of expanded polypropylene, with all its incomparable material properties, in further industries and fields of application.

EPP: Contaminant-free, reusable and sustainable

During the production of expanded polypropylene, no phthalates or other health-harming substances are added. Because of this, at the end of their life, EPP moulded parts can be shredded and made into new parts. The robustness of the material ensures that components made of EPP are very durable. Reusable packaging can therefore be used time and time again over many years. This conserves resources and thus helps to protect our environment.

What’s more, the lightweight nature of components made of EPP, which are used in the automotive industry among others, means that less fuel is consumed and emissions are reduced.

Order a sample case

To give you an understanding of the wide range of possibilities offered by EPP, we have put together a sample case for you. It contains 21 sample plates in various colours and finishes – a real eye-catcher in itself. The case also shows how EPP components can be joined to each other or to other materials. Order a sample case of expanded polypropylene to take home and let yourself be inspired.

The members of the EPP Forum form a representative cross-section of the EPP industry and work together to promote the proliferation and further development of innovative products made of expanded polypropylene.

Our members include well-known companies from the fields of raw material production, tooling and mechanical engineering for EPP processing, moulded parts production, joining technology and design as well as a research institute.

The EPP Forum introduces itself

The EPP Forum was founded in 2006 to raise awareness for EPP as a promising material and to continuously develop it further. The office of the EPP Forum is located at Neue Materialien Bayreuth GmbH, an internationally leading research institute in the field of polymer bead foams.

The remit of the EPP Forum includes the organisation of trade fairs and presentations, networking among members and the transfer of knowledge between companies.
