The variety of soccer balls refers to the size, design and weight differences between models. Plus, the materials used for the construction of the soccer balls are also very diverse, directly influencing the features of the finite products as well as the price. Consider the following technical details that few people know about the structure of the soccer balls.
The surface of soccer balls consists of several coverings that are not made of natural leather as it seems at first sight but they are manufactured from lightweight plastic that keeps the balls dry. Synthetic leather is the most commonly used, being made of poly vinyl chloride or PVC and polyurethane. Even the types of artificial leather remain a mystery to most soccer fans, because these patterns too, come in great number of varieties.
Depending on the design of the soccer balls, the various segments of the exterior cover, also known as the panels, present specific features. There can be 32, 26 or 16 panels with the mention that 32-panel variant is normally used in the majority of official games. Yet, the others are encountered with some leagues in England and Scotland. After being sewn together and inflated, the panels create the nearly perfect sphere that we call soccer ball.
A special material called the lining is used between the internal bladder that holds the air and the outer covering. Laminated cotton or polyester are normally used for the intermediary layer, and they play an important part in the bouncing and strength features of the ball. In the professional design of soccer balls, up to five different linings can be used, although practice balls include fewer linings.
Differences of material do exist in the structure of the bladders as well. Soccer balls can be manufactured either from butyl or latex. While the surface tension brought by latex or natural rubber is unparalleled, the tiny pores in the structure of this material cause the soccer balls to deflate.
This means that you’ll have to re-inflate the ball at least once a week to maintain pressure and keep the ball practical. Butyl soccer balls present no air retention problem, but require valves to keep the air inside.
