What are bowling balls made
of?
- In the 1960s, hard rubber balls were used. Polyester balls took over as the ball of choice
inthe '70s. You will find that most of the 'house balls'in your local bowling alley are made
of the polyester. In the '80s the urethane ball was developed, which then were further developed
to reactive and proactive urethane. |
