Tennis Ball
Tennis Balls are used in the sport of Tennis. Modern Tennis
Balls are made from rubber mixed with 14 to 18 chemicals to get the
proper consistency. Approximately 85% of the ball weight is the rubber/chemical
mix.
Over 90% of Tennis Balls are produced in South Africa where the natural
resource is abundant. The most expensive ingredient in the ball is the
felt, which is adjusted in various ways to produce different properties.
Steaming the felt raises its nap to make it fluffier, which increases
wind resistance and control while reducing bounce and speed. A compact
nap causes the ball to skip on hitting the court or a racket
Pressure-less balls usually have a stiffer, woodier feel than pressurized
balls, and do not bounce as high as brand new pressurized balls. Unlike
pressurized balls, though, they do not lose bounce over time. In fact,
they get bouncier as they get lighter, due to fuzz loss. The balder
they get, the more their flight, bounce, and spin response changes from
what you would expect of tennis balls
