Acrylic vs polycarbonate
Mirror Lens Material FAQ
Compare acrylic and polycarbonate mirror lenses by clarity, impact resistance, weatherability, and use case.
comparisonWhat is the difference between acrylic and polycarbonate mirror lenses?
Acrylic and polycarbonate are both lighter and stronger than glass, but they behave differently. Acrylic provides the brightest image and is a cost-effective choice for most normal-use environments. Polycarbonate is much more impact resistant and is the better choice for vandalism risk, heavy traffic, children, equipment contact, or harsh environments.
selectionWhen should I choose an acrylic mirror lens?
Choose acrylic for most indoor applications and for outdoor locations where heavy impact or vandalism is not expected. Acrylic is bright, lightweight, chemically resistant, and cost effective, making it well suited for retail, offices, warehouses, residential driveways, and many garage installations.
selectionWhen should I choose a polycarbonate mirror lens?
Choose polycarbonate when durability and impact resistance matter most. It is the best lens choice for high-traffic industrial areas, parking garages, schools, exposed outdoor traffic locations, and any place where equipment, vandalism, or repeated impacts are realistic concerns.

comparisonDo acrylic and polycarbonate mirrors provide the same image quality?
Both provide clear reflections, but acrylic generally has the brightest image. Polycarbonate is slightly less bright, but its impact resistance often outweighs that difference in demanding safety applications. For low-risk monitoring where crispness and cost matter most, acrylic is a strong choice.
durabilityAre acrylic and polycarbonate mirrors UV and weather resistant?
Both materials offer good weatherability and UV resistance when specified for outdoor mirror use. Polycarbonate has an advantage in extreme heat, cold, and impact-prone locations. Either material should be paired with an outdoor backing such as HDPE or galvanized steel for exterior installations.

selectionWhich lens material is best for vandal-resistant mirrors?
Polycarbonate is the recommended material where vandalism is a concern because it is far more impact resistant and virtually shatterproof compared with acrylic. Acrylic is durable for normal use, but polycarbonate is the safer choice for schools, public areas, parking garages, and rough industrial environments. As a tangible benchmark, polycarbonate is on the order of 250× more impact-resistant than equivalent glass and is the same material used in bullet-resistant security glazing.
