Short Answer
Table tennis balls are made of a hollow celluloid or plastic material.
The International Table Tennis Federation (ITTF) requires them to be a standard size and weight, and to have a uniform bounce when dropped from a height of about 12 inches.
Table tennis balls are also typically covered with a thin layer of white or orange celluloid material, which helps to reduce the amount of air resistance that the ball experiences when hit.
What is Table Tennis?
Table tennis, also known as ping-pong, is a popular and exciting sport that has been popular since the late 1800s.
It is played on a hard table with a net separating the two sides.
Two or four players hit a lightweight, hollow plastic ball back and forth using wooden or composite paddles.
The goal is to score points by sending the ball over the net and onto the opponent’s side of the table.
Table tennis is a fast-paced and competitive game that requires skill, agility, and strategy.
Table tennis is a sport that is accessible to people of all ages and skill levels, making it a popular pastime for families and friends.
It is also a sport that is played at the highest competitive level, with national and international tournaments taking place around the world.
Table tennis is an Olympic sport, and the best players in the world compete for medals at the Olympic Games.
The Standard Size of a Table Tennis Ball
Table tennis balls are typically 40 millimeters in diameter, as this is the standard size set by the International Table Tennis Federation.
This size ensures consistency among players in tournaments and competitive play.
The exact size of the ball is crucial as it affects how it moves and how it interacts with the paddle surface.
The weight of the ball should also be consistent, according to the rules, as this can also affect the game.
The weight of a single table tennis ball should not exceed 2.7 grams.
If the ball is too light, it will be difficult to control, as it will be too easily influenced by the wind and spin generated by the paddle.
On the other hand, if the ball is too heavy it will be difficult to hit with the right amount of force.
The Components of Table Tennis Balls
Table tennis balls are made up of several components that work together to produce a stable and consistent ball that is suitable for competitive play.
The primary component of a table tennis ball is hollow celluloid plastic.
This plastic is a mix of two parts acetate and one part nitrocellulose, a highly flammable substance.
The plastic is then formed into a 40 millimeter sphere, which is the standard size used in professional and competitive play.
The plastic used to form the ball is made of a hard polymer, making it resilient and long-lasting.
This is important in order for the ball to be able to withstand the impact of a high-speed serve or a hard smash.
The plastic is also colored either white or orange, depending on the surface of the table.
White balls are used on dark surfaces and orange balls are used on light surfaces.
The final component of a table tennis ball is a layer of felt, which is made of a combination of wool and synthetic fibers.
This layer of felt helps to reduce the speed of the ball and gives it a better spin, making it easier to control.
It also helps to reduce the noise produced by the ball when it is hit.
All table tennis balls must be approved by the International Table Tennis Federation in order to be used in official competitions.
This ensures that the ball meets the required standards for competitive play.
The Chemistry Behind The Plastic Used to Make Table Tennis Balls
Table tennis balls are made of a special type of plastic that is a mix of two parts acetate and one part nitrocellulose.
Acetate is a lightweight, transparent plastic made from cellulose acetate, which is derived from wood pulp.
It is a strong, durable material that is resistant to most solvents, making it an ideal material for table tennis balls.
Nitrocellulose, on the other hand, is a highly flammable substance composed of cellulose fibers, nitric acid, and sulfuric acid.
It is used to coat the inside of the celluloid plastic, making the ball stronger and providing it with a glossy finish.
The plastic used to make table tennis balls is a hard polymer, allowing it to be resilient and long-lasting.
The colors of the table tennis balls also depend on the playing surface.
Most professional table tennis balls are white, but some players prefer to use orange balls for outdoor surfaces.
The plastic used to make table tennis balls is approved by the International Table Tennis Federation, ensuring that it meets the necessary standards for competitive play.
The combination of acetate and nitrocellulose make table tennis balls strong and resilient, allowing them to withstand intense matches without breaking.
The hard polymer also gives the balls their glossy finish, allowing them to maintain their vibrant colors even after multiple uses.
Table tennis balls are a great example of how science and technology can be used to create a product that is both strong and long-lasting.
By combining two different types of plastics, the table tennis ball is able to provide a unique level of performance.

The Coloring of Table Tennis Balls
Table tennis balls come in two colors: white and orange. The color of the ball is determined by the color of the playing surface. White balls are used on green or blue surfaces, while orange balls are used on black or brown surfaces. This allows players to easily identify the ball on the court and helps them to better anticipate its movements.
The color of the ball is not just for aesthetic reasons.
Different colored table tennis balls are made of different materials.
White balls are made of a hard plastic polymer that is resilient and long-lasting, while orange balls are made of a softer rubber material that absorbs impact better and provides a slightly slower bounce.
This allows players to adjust their playing style to the type of ball being used, making for a more dynamic and interesting game.
In addition to the materials used, the color of the ball also affects how it reacts to light.
White balls reflect light better, making them easier to spot on the court.
Orange balls absorb light, making them less visible.
This can be advantageous in certain playing conditions as it can make the ball harder to track, giving players an extra edge.
No matter what color the table tennis ball is, it is always 40 millimeters in diameter and made of hollow celluloid plastic.
The plastic is a mix of two parts acetate and one part nitrocellulose, a highly flammable substance.
