There are several different materials and methods of construction used in soccer balls. Typically, Polyurethane casings are preferred as they’re often seamless and thermally bonded for premium play and long-lasting durability. However, many of the hand-stitched options are also very durable. The least durable options tend to be lower in price and machine stitched.
The outside of the soccer ball is typically made from one of two materials: PVC or Polyurethane. PVC is much more affordable and durable, and these are typically seen in training soccer balls because training balls go through much more of a continuous beating. Polyurethane balls are usually even softer than PVC balls and its ability to go where you want it to go is much better than the PVC balls. As a result, these are typically higher-end balls. However, there are still various ways to construct them, and not all PVC or polyurethane balls are created the same. Glossy coatings, which are very popular in the public fields with the kids and adults alike, are also very useful because they help reduce scuffing and the intake of water.
In 1937, the regulation soccer ball put on a little weight, increasing from 13-15 ounces to 14-16 ounces. Soccer balls used to be made exclusively of leather. Not so these days! Current technologies have come up with leather-like synthetic materials that are softer, more lightweight, water-proof, and perform as well if not better than leather soccer balls. As for the look, early soccer balls were tan but difficult to see from the stands; although white leather-washed soccer balls are known to have been used. White soccer balls replaced their tan predecessors in the 1950s, and were composed of 18 panels. Black spots were added to allow soccer players to track the ball's swerve. Today's soccer balls come in an array of colorful designs and styles to suit every player.
Today's footballs are more complex than past footballs. Most modern footballs consist of twelve regular pentagonal and twenty regular hexagonal panels positioned in a truncated icosahedron spherical geometry. Some premium-grade 32-panel balls use non-regular polygons to give a closer approximation to sphericality. The inside of the football is made up of a latex bladder which enables the football to be pressurised. The ball's panel pairs are stitched along the edge; this procedure can either be performed manually or with a machine. The size of a football is roughly 22 cm (8.65 inches) in diameter for a regulation size 5 ball. Rules state that a size 5 ball must be 68 to 70 cm in circumference. Averaging that to 69 cm and then dividing by π gives about 22 cm for a diameter.
One of the main reasons but not the only reason to select this ball for reviewing is the great mission of the company. If you buy one ball, they will donate one ball to the kids of developing countries against your purchase. So, this is a “Buy One, Give One” charity model, and of course, it is a good mission where you can also contribute by buying one.
Soccer balls also need maintenance in order to extend their lifespan. Avoid putting unnecessary pressure into them like standing or sitting on the actual ball. Doing so can damage a soccer ball’s pressure system, making it change its shape and structure. Don’t kick the ball against hard, rocky or rough surfaces as this could puncture it easily. This may also cause you to get a new replacement ball.
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
