Baseball bat

Polyurethane is not commonly used in the manufacturing of baseball bats. Baseball bats are typically made from wood, aluminum, or composite materials.

Wooden baseball bats are most commonly made from maple, ash, or birch wood. They are usually turned on a lathe to create the bat’s shape, and then sanded and finished to provide a smooth surface. Wooden bats are often preferred by professional players because they offer a traditional feel and sound when hitting the ball.

Aluminum baseball bats are made from a combination of aluminum and other metals. They are generally lighter and more durable than wooden bats, and provide a larger sweet spot, making it easier to hit the ball. However, they do not have the same traditional feel and sound as wooden bats.

Composite baseball bats are made from a blend of materials, including carbon fiber and resin. They are often lighter and more durable than both wooden and aluminum bats, and can provide a larger sweet spot as well. However, they can be more expensive than other types of bats.

While polyurethane is a versatile material that can be molded into various shapes and sizes, it is not typically used in the manufacturing of baseball bats. Baseball bat manufacturers have found that other materials, such as wood, aluminum, and composites, offer better performance characteristics for this particular application.
