Leverkusen, Germany -- Materials supplier Covestro and Adidas developed the European Championship ball, the Beau Jeu - named after the French for beautiful game.
According to Covestro, the “improved ball control and stable flight characteristics” of the ball, as well as its water resistance, are due to the PU in its outer shell.
Covestro’s manager for ball development Thomas Michaelis said: “The ball’s outer shell consists of five layers based on polyurethane raw materials from the Impranil line.”
“It starts with the outermost skin, a full underglass print that prevents abrasion of the printed layer.”
The firm said the ball’s “underlying intermediate layer protects it against external influences and lends it unusually high elasticity.”
Beneath that is a polyurethane foam with "millions of microspheres" ensure outstanding flight characteristics, the firm added.
Lastly, a polyurethane adhesive bonds the top layers to a polyester-cotton fabric substrate.
The creation of Beau Jeu also marks the 30th anniversary of sports goods manufacturer Adidas and materials supplier Covestro collaborating on ball innovation.
Covestro also developed the Brazuka – the ball used in the 2014 World Cup, as UTECH-polyurethane.com reported at the time.
