2. Twinwall plastic - Wikipedia

   en.wikipedia.org/wiki/Twinwall_plastic

   Roofing sheets made from twinwall plastic are primarily 10mm thick, however, they are also available in greater thicknesses such a 16mm, 25mm and 35mm. Any thickness over 10mm would usually be called a Multiwall Plastic Sheet due to having multiple internal layers. Twinwall plastic can refer to several different extruded polymers including:

4. Polycarbonate - Wikipedia

   en.wikipedia.org/wiki/Polycarbonate

   Polycarbonate has a glass transition temperature of about 147 °C (297 °F), [8] so it softens gradually above this point and flows above about 155 °C (311 °F). [9] Tools must be held at high temperatures, generally above 80 °C (176 °F) to make strain-free and stress-free products.

5. UL 94 - Wikipedia

   en.wikipedia.org/wiki/UL_94

   UL 94, the Standard for Safety of Flammability of Plastic Materials for Parts in Devices and Appliances testing, is a plastics flammability standard released by Underwriters Laboratories of the United States. [1] The standard determines the material's tendency to either extinguish or spread the flame once the specimen has been ignited.

6. Tritan copolyester - Wikipedia

   en.wikipedia.org/wiki/Tritan_copolyester

   Tritan, a copolymer offered by the Eastman Chemical Company since 2007, is a transparent plastic intended to replace polycarbonate, because of health concerns about Bisphenol A (BPA). [1] [2] Tritan is a copolymer made from three monomers: dimethyl terephthalate (DMT), cyclohexanedimethanol (CHDM), and 2,2,4,4-Tetramethyl-1,3-cyclobutanediol ...

7. Poly(methyl methacrylate) - Wikipedia

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

   PMMA transmits up to 92% of visible light (3 mm (0.12 in) thickness), [18] and gives a reflection of about 4% from each of its surfaces due to its refractive index (1.4905 at 589.3 nm). [3] It filters ultraviolet (UV) light at wavelengths below about 300 nm (similar to ordinary window glass).
