Urethane Bowling Balls

• Designed for much hook.• Drags across lane providing less friction and

more speed.

Resin Bowling Balls

• Does not drag across lane because of increased friction so it travels slower. Much friction on surface and lane which creates most hook.

Particle Bowling Balls

• A resin ball with glass pieces added to create more grit, to help it grip to the lane.

• Most PBA bowlers prefer a particle ball because hook is easiest to control.

Polyester Bowling Balls

• The most common type of bowling and the cheapest to manufacture. Polyester is plastic.

• They last the longest.• Polyester bowling balls are hardest to control.

How Are They Made

• A bowling ball starts off as a core made of weighted materials.

• If it is a 6-10 pound ball then it will usually have a hard foam core.

• Anything heavier consists of a metal core.

How Are They Made

• The coverstock is a shell that surrounds the core of a bowling ball.

• The coverstock is what is made of Urethane, Resin, Particle, and Polyester
