This balloon has a story for you
After a long period of observation, our design team came up with this lighter ball, while retaining the technical characteristics of a traditional soccer ball.
Its winding bladder (2 kms of thread winding around the bladder) guarantees more resistant inflation over time and better sphericity.
Lighter than a traditional balloon
This model is called "Light" because it is on average 15% lighter than a conventional football in size 4. What's the difference? Thanks to its weight, it will be more pleasant for our young footballers to kick the ball or make a header.
They will also find it easier to make long passes or aim for the top corner: guaranteed fun!
Too light? Too heavy? The weight is standardized...
This ball weighs between 280g and 300g, compared with 350g and 390g for a traditional size 4 soccer.
What size, what circumference?
The size of this ball is between 63.5cm and 66.0cm (size 4).
A round ball, really?
We measure the sphericity of the ball at 4,500 different points and look at the deviations observed.
If the deviation exceeds 1.8% (FIFA standard), our engineers are tasked with improving the sphericity to guarantee a regular rebound.
Maximum pressure loss test: we tell you...
We inflate the balloon to the recommended pressure (i.e. 0.8 bar).
72 hours later, the balloon should have lost no more than 15% of its pressure, i.e. around 0.1 bar. The pressure after 72 hours should therefore be around 0.7 bar.
This also means that it's perfectly normal for a balloon to lose pressure after a few days.
We also tested the balloon's water absorption ...
In the laboratory, we simulate playing conditions in the rain by soaking the ball in 2 cm of water on a pivoting support while applying 250 compressions.
At the end of the test, the ball should have gained no more than 15% of its weight, i.e. around 43 grams for this size 4 ball.
When the rebound goes, everything goes
Between 115 and 155 cm, with a maximum difference of 10 cm between the highest and lowest bounce per ball. Each ball is released 10 times onto a steel plate from a height of 2 meters.
Not bad at all!
The most demanding test we put this ball through is the machine shoot test.
The ball must withstand 2,500 shots against an inclined concrete surface at 50km/h from a distance of 2.5m.
At the end of this test, we check:
-the general condition of the ball: the seams must withstand this test.
-the circumference: it must not have increased by more than 1.5cm.the circumference: it must not have increased by more than 1.5cm.
-the sphericity: it must not have varied by more than 1.8%.
-the pressure: the ball must not have lost more than 12.5%.
