Altuglas HT 121 is a polymethyl methacrylate that withstands temperatures to 100°C. The acrylic also features a Vicat softening temperature of 121°C, and resists scratches and impacts (reportedly up to 10 better than glass of comparable thickness), UV, and weather. It comes in several colors and accepts all finishes and needs little surface protection, making it a good candidate for automotive and motorcycle headlights, mobile-phone screens, and other lighting applications.
