The official match ball of the
2014 World Cup – has a unique symmetry of six identical propeller-shaped polyurethane panels
being thermally bonded together, alongside a different surface structure that
will provide improved grip, touch, stability and aerodynamics on the pitch. The
ball weighs 437 grams and has a circumference of 69 cm. It offers a water absorption rate of 0.2%,
meaning it can retain its shape, size and weight even in the rain. It is worth mentioning that the brazuca ball
had to stand high speed spin cycles in a washing machine as well as robot kicks
of up to 160 km/h to test its waterproofness and durability.
The name "brazuca”, meaning the Brazilian way of life, was chosen by over 1
million football fans in September 2012.
