When it comes to building an aquarium, one of the most important decisions you'll have to make is whether to use cast or extruded acrylic. Both materials have their pros and cons, and choosing the right one can make a big difference in the look and durability of your aquarium. In this article, we'll take a closer look at the differences between cast and extruded acrylic and help you decide which one is right for your needs.
What is Acrylic?
Acrylic is a type of plastic that is lightweight, shatter-resistant, and has excellent optical clarity. It is often used as a substitute for glass in applications where safety and durability are a concern, such as in aquariums.
Cast Acrylic
Cast acrylic is made by pouring liquid acrylic resin into a mold and then allowing it to cure. This process creates a material that is highly durable, has excellent optical clarity, and is resistant to scratching and UV damage. Cast acrylic is also available in a wide range of colors and thicknesses, making it a versatile choice for aquariums.
Extruded Acrylic
Extruded acrylic is made by pushing acrylic resin through a die to create long, continuous sheets. This process creates a material that is less expensive than cast acrylic but is also less durable and has lower optical clarity. Extruded acrylic is also more prone to scratching and UV damage than cast acrylic.
