Besides just its sleek exterior, the Adidas Starlancer is crafted with longevity in mind by the nylon being wound internally and assembled through machine stitching to provide it with an extra level of strength. The exterior is made of TPU material, which is ideal for resisting cuts and scrapes. The bladder which holds the air is Butyl, which works wonders in keeping the shape of the ball perfect at all times.
Latex bladders are used in high-quality balls. These kind of bladders are soft and provide good feeling. They offer better response and bounce than Butyl bladders, but the downside of this kind of bladder is they don’t hold the air for too long. As a result, they require filling more frequently. Air escapes due to micropores on the cover, but nowadays some balls are constructed with carbon latex bladder to help to close these micropores. As a result, the balls can hold air for a longer period.
Adidas says its design was motivated by Russia's urban landscapes. It uses textured graphics and a metallic sheen to bring a modern look to the classic design. The ball is made of six panels of thermally bonded TPU and about 15% silicone. The materials allow for better trajectory, accuracy, responsiveness, and low water absorption. It also feels well-padded and slightly lighter than previous match balls.
Inflate soccer balls to the pressure of 6-8 PPI (pounds per square inch). A pressure gauge will tell you when the air is enough. Under or over-inflating a soccer ball will shorten its life in one way or another. When under-inflated, the ball will not be resistant to the impact of kicks. On the other hand, over inflation will stretch out the bladder and put pressure on the panel stitches.
The soccer ball has gone through various changes just as the football game. As opposed to yesterday’s football ball that had stitches and seams and the classic black and white design, today’s soccer balls are designed with the latest technology that lets the ball bend more, fly quicker and also dip harder. Besides, they are quite soft that they let players kick the ball further without risking injuries. https://www.youtube.com/watch?v=DGp37du0xbQ
