Lacrosse balls have been made out of several different materials throughout the history of lacrosse, but the modern lacrosse ball is made of solid rubber. Different lacrosse brands produce their lacrosse balls differently and with varied formulas. Despite these differences, all lacrosse balls used in lacrosse games must be a NOCSAE certified lacrosse ball. A NOCSAE certified lacrosse ball conforms to specific standards that make it legal for competitive play in lacrosse games. You can learn more about lacrosse balls in our Lacrosse Ball Buying Guide!
What Were Lacrosse Balls Made of?
Just as it says above, lacrosse balls have been made out of many different materials throughout the history of the game of lacrosse. The earliest lacrosse balls were made from buckskin, wood, or sometimes rock. These lacrosse balls were naturally occurring and kept the game connected with nature. It was not until after Dr. William George Beers wrote down rules to the game of lacrosse in the 1860's that lacrosse balls became more uniform.
What Are Lacrosse Balls Made of Now?
The modern lacrosse ball must be made out of a solid, elastomeric material according to standards set forth by NOCSAE. There are many elastomeric materials available to lacrosse ball manufacturers, such as silicone, polyurethane, rubber, and various types of vinyl. Most modern lacrosse balls are produced with solid, vulcanized rubber.
Vulcanizing rubber makes it stronger and mixes natural rubber with other additives. The process of vulcanizing rubber is very common and often used in the production of footwear.
What's Inside A Lacrosse Ball?
You may have heard someone ask, 'are lacrosse balls made of cement?' and thought it sounded strange. Well, at one point, some lacrosse balls had cement in the middle of them. This era is behind us, and most of these lacrosse balls are no longer in existence. None of these lacrosse balls with cement in the inside of them are legal for play.
All NOCSAE certified lacrosse balls must be made of a solid, elastomeric material. That means that all NOCSAE certified lacrosse balls are one material through and through. You can even cut a lacrosse ball in half to see that the middle of a lacrosse ball is essentially the same as the outside. Each NOCSAE certified lacrosse ball is 7.75 inches to 8.0 inches in circumference of one material that's most likely vulcanized rubber.
