2. Polycarbonate - Wikipedia

   en.wikipedia.org/wiki/Polycarbonate

   Polycarbonate is commonly used in eye protection, as well as in other projectile-resistant viewing and lighting applications that would normally indicate the use of glass, but require much higher impact-resistance. Polycarbonate lenses also protect the eye from UV light.

3. Sandwich panel - Wikipedia

   en.wikipedia.org/wiki/Sandwich_panel

   Sandwich panels have λ-values from 0.024 W/(m·K) for polyurethane to 0.05 W/(m·K) for mineral wool. Therefore, they can achieve different U-values depending on the core and the thickness of the panel. The installation of a system with sandwich panels minimizes thermal bridges through the joints.

   en.wikipedia.org/wiki/Poly(methyl_methacrylate)

   The polymer separated from the glass as a clear plastic sheet, which Röhm gave the trademarked name Plexiglas in 1933. [5] Both Perspex and Plexiglas were commercialized in the late 1930s. In the United States, E.I. du Pont de Nemours & Company (now DuPont Company) subsequently introduced its own product under the trademark Lucite.

7. Fiberglass - Wikipedia

   en.wikipedia.org/wiki/Fiberglass

   A suitable resin for combining the fiberglass with a plastic to produce a composite material was developed in 1936 by DuPont. The first ancestor of modern polyester resins is Cyanamid's resin of 1942. Peroxide curing systems were used by then. [6] With the combination of fiberglass and resin the gas content of the material was replaced by plastic.
