Plastic boomerangs

The first boomerangs were made of raw wood. Aborigines used mulga, a hard wood that is made of compact fibers. It is relatively resistant but it performs poorly. As plastic materials were created and the shapes of boomerangs evolved, high-performance boomerangs became more widely available at competitive prices, leading to this special sport becoming more popular. Many kinds of plastics are used to produce boomerangs.

Each plastic material has its own mechanical properties and density. The main process in boomerang manufacture is to inject melted plastic at a high pressure into a mold that lies embedded in a matrix. Many so-called boomerangs are made this way, but very few are of good quality and they often end up in supermarkets where they are sold as beach toys. Our plastic boomerangs are not simple beach toys, but genuine sports equipment designed by the world’s best throwers. Here is a list of the plastics most often used to produce boomerangs: Polypropylene: It’s the most commonly used material in the production of boomerangs. Also known as "PP", Its lightness makes it possible to produce boomerangs that are stiff and yet soft enough to be tuned (dihedral and angle of attack). The only drawback: polypropylene must be kept away from the cold.

ABS: A harder, brighter plastic with a perfect finish. ABS plastic increases boomerang speed. The COACH, an ABS boomerang, is an excellent model. An ABS boomerang is steadier and will not warp. However, polypropylene feels softer than ABS plastic. Polycarbonate: This plastic is less commonly used though it has interesting mechanical properties since it is almost impossible to break. It is indeed the most resistant plastic of all. However, because this plastic is heavier and denser, it is more difficult to throw a polycarbonate boomerang.
