Bio-based rubber to give “optimal bounce” to official ball of the FIFA World Cup 2018.

The EPDM rubber is the basis for a sponge rubber layer directly underneath the Telstar 18 balls outer cover. It serves as a moldable cushion for the ball and supports optimal bounce characteristics during games according to the team behind it. Keltan Eco is the worlds first EPDM rubber manufactured using bio-based ethylene extracted from sugarcane.

For us, ecological sustainability was a fundamental criterion in the selection of products for the World Cup soccer ball, says Stefan Bichler, project manager of Football Operations at adidas AG. We wanted to create the new soccer ball using high-tech materials that have impressive performance characteristics and are also sustainable.

Materials that are used in this layer must meet strict requirements in properties such as density, hardness and weight, and they must also demonstrate good processability. The most important performance characteristic, however, is the elasticity and resilience of the layer.

Keltan Eco has the renowned quality characteristics as EPDM rubber that is made using fossil raw materials, says Martin Kleimeier, project director and Global Marketing Manager for the ARLANXEO Keltan business line. With the full Keltan Eco portfolio, we have developed EPDM products that save resources, reduce our use of fossil-based products and also have a carbon footprint that is significantly lower than conventionally manufactured polymers, adds Chretien Rooijakkers, Head of Global Marketing for the ARLANXEO Keltan business line.

Since end of 2011 ARLANXEO has produced bio-based EPDM rubber at its Triunfo site in Brazil. Bio-based ethylene is produced by Braskem, their partner, and flows directly by pipeline to their EPDM plant.

Depending on the ethylene content of each rubber grade, the proportion of bio-based material ranges between 50 and 70 percent. Keltan Eco 6950 the type used by adidas is characterized by its amorphous structure and high crosslinking density. This leads to good low-temperature properties and meets the requirements for the best possible elasticity and resilience.

With six different grades of Keltan Eco rubber currently on the market, ARLANXEO, established in April 2016 as a joint venture of LANXESS and Saudi Aramco, is supporting the move towards more sustainable products and matching the ever stricter environmental requirements to help reduce its carbon footprint, whether in the sporting goods industry or the automotive industry. Other areas of application include artificial turf and athletics tracks.
