What Are Ping Pong Balls Made From

An Introduction

Ping pong, also known as table tennis, is a sport loved and played by many around the world. But have you ever stopped to wonder what those tiny bouncing balls that we smack back and forth across the table are made of? Well, you’re not alone. In this post, we will delve deeper into the nitty-gritty details of what these ping pong balls are made from and why. So grab your paddle and let’s get started!

A Glimpse into the Past

The ping pong balls that we know today didn’t appear out of nowhere. They have a rich history that tells the story of their evolution and material modifications over the years.

The Early Days

In the initial days, the early ping pong balls were made from various materials such as rubber, cork, and even chalk. Rubber, being relatively bouncy and lightweight, was one of the favored choices. However, these balls tended to degrade quickly, leading to inconsistent play.

The Celluloid Era

With technological advancements came the introduction of celluloid balls at the beginning of the 20th century. The celluloid, a type of plastic, provided greater durability, consistency, and bounce in comparison to the earlier versions. Its light yet robust nature captured the essence of what a ping pong ball should ideally be like.

New-age Plastic Balls

In 2011, the International Table Tennis Federation (ITTF) made a decision to move away from celluloid and towards plastic balls due to the concerns over celluloid’s flammability. These new plastic balls, also known as Poly balls, offer similar characteristics to celluloid ones but with better fire safety.

Understanding Ball Construction

Now that we have discussed the materials, let’s have a look at what goes into manufacturing a ping pong ball to meet certain standards.

The Two Halves

A standard ping pong ball is not made from one single piece of material. Instead, it consists of two identical half-spheres that are heated and pressed together. This fusion process forms the almost seamless, smooth appearance that we see.

Sizing Matters

According to ITTF, the standard size of a table tennis ball should be 40mm in diameter. However, it hasn’t always been this way. Before 2000, the standard size was 38mm. The size was increased to slow down the game and make it more appealing to television audiences.

Test for Quality

Ping pong balls undergo stringent quality checks to ensure they meet certain performance standards. These include tests for roundness, bounce, weight, and hardness. A standard ball must weigh 2.7 grams and must bounce 240–260 mm when dropped from a height of 305 mm.

Environmental Impact

As consumers, it’s important to consider the environmental impact of the products we use, including ping pong balls.

Plastic Pollution

Modern ping pong balls are made from plastic, which as we know, can take hundreds to thousands of years to decompose. This calls for proper disposal habits among users and better recycling initiatives from manufacturers.

Biodegradable Options

A step in the right direction is the introduction of biodegradable ping pong balls. Made from renewable materials like bamboo, these balls offer a more environmentally friendly option for play without compromising on performance.

Recycling Possibilities

While it’s tricky to recycle ping pong balls due to their small size, creative solutions are surfacing to deal with this issue. From DIY craft projects to specialty recycling programs, there are ways to give these balls a new life after they’ve done their time on the ping-pong table.


The humble ping pong ball, while small in size, carries within it a rich tapestry of history, design, and environmental implications. As technology continues to advance, and as we become more conscious of our environmental footprints, it will be exciting to see how these tiny orbs of fun will evolve and adapt. For now, though, whether you’re playing a casual game with friends or going pro, just remember to recycle!
