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. Twinwall plastic - Wikipedia

   en.wikipedia.org/wiki/Twinwall_plastic

   Twinwall plastic most commonly refers to two exterior plastic sheets that are connected with a plastic support layer to create parallel channels. This design adds both impact toughness and the ability to support weight. Twinwall plastic may also be used to describe a pipe that has a smooth interior with exterior air filled ridges. [3]

4. Polyvinyl butyral - Wikipedia

   en.wikipedia.org/wiki/Polyvinyl_butyral

   In practice, the interlayer provides three beneficial properties to laminated glass panes: first, the interlayer functions to distribute impact forces across a greater area of the glass panes, thus increasing the impact resistance of the glass; [citation needed] second, the interlayer functions to bind the resulting shards if the glass is ...

5. Tygon tubing - Wikipedia

   en.wikipedia.org/wiki/Tygon_Tubing

   Tygon Fuel and Lubricant Tubing F-4040-A is translucent yellow for positive identification and flow monitoring. It is used in small engine fuel lines, recreational vehicles, and lubrication lines. Tygon LP1100 is a low permeation EPA and CARB certified fuel line [4] also used in small engines. Tygon R-3400 UV Resistant Tubing is

6. Poly(methyl methacrylate) - Wikipedia

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

   It is a transparent thermoplastic, used as an engineering plastic. PMMA is also known as acrylic, acrylic glass, as well as by the trade names and brands Crylux, Hesalite, Plexiglas, Acrylite, Lucite, and Perspex, among several others . This plastic is often used in sheet form as a lightweight or shatter-resistant alternative to glass. It can ...

7. Anti-scratch coating - Wikipedia

   en.wikipedia.org/wiki/Anti-scratch_coating

   Scratch-resistant coatings are added to glasses due to scratches' extreme ability to impact a wearer's vision. Even when optical glasses are made of high scratch-resistances glass, polycarbonate, or CR-39, coatings are still used. Optical coatings include diamond-like carbon (DLC) and anti-reflective-scratch hybrid coatings. Diamond-like Carbon ...
