World Cup 2018 Soccer Ball with Bio-Based EPDM Rubber
The new official soccer ball of the World Cup 2018 from adidas contains the bio-based EPDM rubber Keltan Eco from Arlanxeo, one of the world’s leading suppliers of synthetic rubber. The EPDM rubber (ethylene-propylene-diene monomer) Keltan Eco 6950 is the rubber basis for a sponge rubber layer directly underneath the “Telstar 18” ball’s outer cover. It serves as a moldable cushion for the ball and supports optimal bounce characteristics during games.
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.
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.”
Keltan Eco is the world’s first EPDM rubber manufactured using bio-based ethylene extracted from sugarcane. Depending on the ethylene content of each rubber grade, the proportion of bio-based material ranges between 50 and 70 %. 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.
