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.

Several covering layers are included in the surface structure of the soccer balls and they are not made of natural leather as it may appear at first sight but rather from synthetic materials that keep the balls lightweight even when it’s damp outside. Poly vinyl chlorine or PVC and polyurethane or PU are the main materials used for synthetic leather production. Even the varieties of artificial leather remain a mystery to most soccer fans, because these patterns too, come in great number of varieties.

The specific features in the exterior cover of soccer balls consist of several segments known as panels. A soccer ball can be made of 16, 26 or 32 panels, with the latest being the official variant for most leagues and championships. Yet, the others are popular in all sorts of major leagues as well, mainly 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.

As for the bladders that actually keep the soccer balls inflated, differences do appear here as well, particularly because of the nature of the materials. Soccer balls can be manufactured either from latex or butyl. While natural rubber or latex creates a great surface tension, the tiny pores in the structure of this material cause the soccer balls to deflate.

In order to keep the ball practical, you’ll have to re-inflate it at least once a week. Butyl soccer balls on the other hand have an excellent air retention capacity and rely on valves for this process.
