2. Acrylonitrile butadiene styrene - Wikipedia

   en.wikipedia.org/wiki/Acrylonitrile_butadiene...

   Acrylonitrile butadiene styrene (ABS) (chemical formula (C 8 H 8) x · (C 4 H 6) y · (C 3 H 3 N) z) is a common thermoplastic polymer. Its glass transition temperature is approximately 105 °C (221 °F). [4] ABS is amorphous and therefore has no true melting point. ABS is a terpolymer made by polymerizing styrene and acrylonitrile in the ...

3. Sunglasses - Wikipedia

   en.wikipedia.org/wiki/Sunglasses

   Sunglasses of this type are sometimes called mirrorshades. A mirror coating does not get hot in sunlight and it prevents scattering of rays in the lens bulk. Sunglass lenses are made of either glass, plastic, or SR-91. Plastic lenses are typically made from acrylic, polycarbonate, CR-39 or polyurethane. Glass lenses have the best optical ...

4. Royalex - Wikipedia

   en.wikipedia.org/wiki/Royalex

   Thus Royalex can be designed to form virtually any finished thickness to suit the end application. One just adds extra sheets. Since ABS has a poor resistance to UV a thin outer layer of UV resistant vinyl is generally included. This can be self-coloured or painted. ABS is a copolymer of rubber and thermoplastic: Acrylonitrile, butadiene ...

5. Thermoplastic - Wikipedia

   en.wikipedia.org/wiki/Thermoplastic

   It is resistant to moisture and most of the chemicals. It is flexible at room temperature (and low temperature) and can be heat sealed. Since it is an inexpensive plastic it is made in large amounts to cater to the demand. For example: ultra-high-molecular-weight polyethylene (UHMWPE) is tough and resistant to chemicals. It is used to ...

6. Styrene-acrylonitrile resin - Wikipedia

   en.wikipedia.org/wiki/Styrene-acrylonitrile_resin

   It is widely used in place of polystyrene owing to its greater thermal resistance. The chains of between 70 and 80% by weight styrene and 20 to 30% acrylonitrile. [1] Larger acrylonitrile content improves mechanical properties and chemical resistance, but also adds a yellow tint to the normally transparent plastic. [2]
