RCS greenline I reduce the
overall carbon fotprint
The next generation of rail encapsulation: RCS greenline
It is not only urbanisation that is advancing in leaps and bounds. The topic of sustainability is also becoming ever more present. The constant tightening of emission protection limits and the growing demand for sustainable products also require new, innovative materials and combinations in the production of modern insulation solutions.
We are rising to the challenge and a more sustainable RCS® will be launched in the future. The carbon black content is partially or completely substituted with a „functional filler“ made of wood. Thanks to the negative CO₂ footprint of the alternative material, the balance of our product will be significantly improved. The new filler material results in a significantly higher insulation of the RCS® and a reduction in density. This makes it even more efficient against stray current and also lighter. All previous advantages for structure-borne sound insulation as well as the easy handling of our system remain unchanged.
Reduce the overall carbon footprint
Renewable Functional Fillers are the sustainable solution to substitute fossil-based and highly CO₂-intensive carbon black in rubber applications. RFF will be produced by converting sustainably sourced hardwood via innovative processes and conversion technologies.
Reducing CO₂ emissions throughout the lifecycle of rubber products is the primary objective to mitigate global warming. RFF has a more than 90% lower carbon footprint than a standard furnace and thermal carbon blacks. Consumer preferences and regulatory pressure call for replacing fossil-based materials with renewable products.
WHAT DOES RFF OFFER? Lightweight materials are an important element, especially in the transportation for better fuel economy. RFF has a more than 25% lower material density (1.3 g/cm3) than traditional functional fillers. This unique natural feature reduces overall rubber compound density and the weight of the end-products. Depending on compound design (i.e., rubber type, filler to be replaced, and actual filler loading), final weight savings of up to 25% can be achieved.
Matthias Klug (Managing Director from SEALABLE Solutions GmbH) particularly emphasises these advantages:
"RFF is a PAH-free product, making it a safe solution to produce rubber products that come in contact with humans. In addition, it is a 100% electrical insulating product."
This feature effectively prevents electrochemical corrosion when in direct contact with light metal alloys based on magnesium and aluminium, thus improving the lifetime of the metal parts.

A new state-of-the-art biorefinery in Leuna
built by UPM Biochemicals
Since 2021, our developers have been testing a new, sustainable generation of rubber together with the experts at UPM Biochemicals. The wood-based biochemicals offer a future-proof solution for a wide range of industries and applications to transform the entire chemical value chain and circular economy.
UPM's extensive knowledge and expertise in renewable wood biomass from sustainable resources comes from over 100 years of history. It forms the basis of the business model and this is how UPM developed into a global leader in bio-based forestry. They consider the multifunctional wood-based biochemicals as a substitute for fossil raw materials. Their use is the next natural step in the evolution of wood use.
With the construction of the new biorefinery in Leuna, they are a regional partner for future, resource-saving projects in the rubber industry.
