Plastic
Acrylic is a clear, amorphous plastic. It's commonly used as a lightweight, non-fragile alternative to glass. It's a thermoplastic which means it melts when heated to a certain temperature. This makes it a viable option for injection molding.
Acrylic is known for its optical clarity, so it's most commonly used in transparent applications. It can be colored or uncolored. Acrylic is commonly referred to as Plexiglass, which is actually a branded type of acrylic.
