Changes in temperature will also affect the inflation level of the soccer ball. Extreme heat or extreme cold will alter the shape of the bladder and this will affect the integrity of the soccer ball. Although it doesn’t seem like you could reach an extreme temperature that could do this to a soccer ball, just leaving a ball in your trunk or the back of a van on a hot Summer’s day will do it.
The Obsidian 5 has trademark graphics paying tribute to the USA national team. It is a prestigious soccer ball to add to your soccer equipment if you love buying anything US. The material used is 12% EVA, 13% polyester, 15% polyurethane and 60% rubber. These top-quality materials ensure great performance and excellent ball control to help improve your playing skills in the field. The material is durable enough to handle day to day use, and machine-stitched construction reduces water absorption while equally ensuring durability. It has a rubber bladder that enhances air retention and shape.
Latex bladders are one of the best materials when it comes to ball construction. However, with latex bladders, air won’t last as long as butyl bladders and will need more attention for proper inflation. Butyl-blend bladders hold in the air much better, but they are harder and less receptive in play. Mid-priced balls will usually have a mix of butyl and rubber. https://www.youtube.com/watch?v=c1SVcjYY6TE
