What is a defining feature of acrylic?

A defining feature of acrylic is that it can be transparent or opaque, which highlights its versatility as a material. This property enables acrylic to be used in a wide range of applications, from display cases and signs to protective barriers and lenses. Manufacturers can produce acrylic in various colors and levels of transparency, allowing for creative designs while still maintaining durability.

The other options do not accurately reflect the characteristics of acrylic. It is not soft and malleable like some other materials; instead, acrylic is known for being rigid and sturdy, making it a popular choice in situations where strength is important. While acrylic is lighter than glass, it is not considered very heavy, as it typically weighs significantly less than similar thicknesses of glass. Furthermore, while acrylic can be affected by UV light and other environmental factors, it is less prone to degradation than some materials when properly treated, allowing it to be used outdoors with appropriate precautions.
