2. Twinwall plastic - Wikipedia

   en.wikipedia.org/wiki/Twinwall_plastic

   Twin-wall plastic, specifically twin-wall polycarbonate, is an extruded multi-wall polymer product created for applications where its strength, thermally insulative properties, and moderate cost are ideal. [1] Polycarbonate, which is most commonly formed through the reaction of Bisphenol A and Carbonyl Chloride, is an extremely versatile ...

3. Polycarbonate - Wikipedia

   en.wikipedia.org/wiki/Polycarbonate

   extrusion into tubes, rods and other profiles including multiwall; extrusion with cylinders into sheets (0.5–20 mm (0.020–0.787 in)) and films (below 1 mm (0.039 in)), which can be used directly or manufactured into other shapes using thermoforming or secondary fabrication techniques, such as bending, drilling, or routing. Due to its ...

4. List of flat panel display manufacturers - Wikipedia

   en.wikipedia.org/wiki/List_of_flat_panel_display...

   Organic light emitting diode (or OLED displays) is a thin, flat panel made of glass or plastic used for electronically displaying information such as text, images, and moving pictures. OLED panels can also take the shape of a light panel, where red, green and blue light emitting materials are stacked to create a white light panel.

5. Covestro - Wikipedia

   en.wikipedia.org/wiki/Covestro

   Covestro AG is a German company producing polyurethane and polycarbonate raw materials. Products include isocyanates and polyols for cellular foams, thermoplastic polyurethane and polycarbonate pellets, as well as polyurethane based additives used in the formulation of coatings and adhesives.

6. Flat-panel display - Wikipedia

   en.wikipedia.org/wiki/Flat-panel_display

   A flat-panel display (FPD) is an electronic display used to display visual content such as text or images. It is present in consumer, medical, transportation, and industrial equipment. Flat-panel displays are thin, lightweight, provide better linearity and are capable of higher resolution than typical consumer-grade TVs from earlier eras.

7. Sandwich panel - Wikipedia

   en.wikipedia.org/wiki/Sandwich_panel

   Sandwich panels are an example of a sandwich-structured composite: the strength and lightness of this technology makes it popular and widespread. Its versatility means that the panels have many applications and come in many forms: the core and skin materials can vary widely and the core may be a honeycomb or a solid filling.

8. Twisted nematic field effect - Wikipedia

   en.wikipedia.org/wiki/Twisted_nematic_field_effect

   OFF state. In the OFF state, i.e., when no electrical field is applied, the nematic liquid crystal molecules form a twisted configuration (aka helical structure or helix) between the two glass plates, G in the figure, which are separated by several spacers and coated with transparent electrodes, E 1 and E 2.

9. Carbon nanotube - Wikipedia

   en.wikipedia.org/wiki/Carbon_nanotube

   For multiwall carbon nanotubes, ISO/TR 10929 identifies the basic properties and the content of impurities, [143] while ISO/TS 11888 describes morphology using scanning electron microscopy, transmission electron microscopy, viscometry, and light scattering analysis. [144] ISO/TS 10798 is also valid for multiwall carbon nanotubes. [138]
