How do acrylic and polycarbonate compare for impact and scratching?

Impact resistance describes resistance to a strike or shattering; it does not describe surface hardness or scratch resistance. NSM uses approximate material comparisons of 15× glass for acrylic and 250× for polycarbonate. Published figures vary by grade, thickness and test: Advanced Plastiform, for example, cites about 10× for acrylic and 250× for polycarbonate. Acrylic is generally more scratch resistant than uncoated polycarbonate, while glass is harder at the surface. These material comparisons are not a model-specific test rating or a bullet-resistance certification.

How should I clean and care for an acrylic mirror?

Use spray wax or plastic polish on the front surface and wipe with a clean, soft cloth. Do not use glass cleaners. Washing with a soft cloth works, but repeated washing can gradually create fine scratches. Read the Acrylic Mirror Care guide for cleaning, drilling, and fastener precautions.

How do I choose the right mirror for my space?

Start with the application — driveway exit, warehouse aisle, blind intersection, retail surveillance, or vehicle inspection — then size by viewing distance using the 1 inch of diameter per 1 foot of viewing distance rule. If you'd like a recommendation, contact NSM with your installation context and we'll narrow the right size, lens, backing, and mount.

What if I need help picking the exact configuration?

Use the live options table above to compare every purchasable row by size, bracket, and price. If you're between two configurations, contact NSM directly before checkout — bulk pricing, government quotes, and project-specific sizing guidance are all available at no charge.
