  2. Polycarbonate - Wikipedia

    en.wikipedia.org/wiki/Polycarbonate

    A major polycarbonate market is the production of compact discs, DVDs, and Blu-ray discs. [13] These discs are produced by injection-molding polycarbonate into a mold cavity that has on one side a metal stamper containing a negative image of the disc data, while the other mold side is a mirrored surface.

  3. Polycarbonate (functional group) - Wikipedia

    en.wikipedia.org/wiki/Polycarbonate_(functional...

    A polycarbonate is an oxocarbon dianion consisting of a chain of carbonate units, where successive carbonyl groups are directly linked to each other by shared additional oxygen atoms. That is, they are the conjugate bases of polycarbonic acids , the conceptual anhydrides of carbonic acid , or polymers of carbon dioxide .

  4. Twinwall plastic - Wikipedia

    en.wikipedia.org/wiki/Twinwall_plastic

    6mm Twinwall Polycarbonate Sheet. 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 ...

  5. Poly(trimethylene carbonate) - Wikipedia

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

    Poly(trimethylene carbonate) (PTMC) is an aliphatic polycarbonate synthesized from the 6-membered cyclic carbonate, trimethylene carbonate (1,3-propylene carbonate or 1,3-Dioxan-2-one). Trimethylene carbonate (TMC) is a colorless crystalline solid with melting point ranging between 45°C and 48 °C and boiling point at 255°C (at 760 mmHg).

    Properties Chemical formula. C 18 H 20 O 2: Molar mass: 268.356 g·mol −1 Appearance White solid ... It is a precursor to specialty polycarbonate plastics. [1]

  7. Polymer solution casting - Wikipedia

    en.wikipedia.org/wiki/Polymer_solution_casting

    The polymer solution casting process utilizes a mandrel, or inner diameter mold, that is immersed in a tank of polymer solution or liquid plastic that has been specifically engineered for the process. Due to a combination of thermal and frictional properties, the polymer solution then forms a thin film around the mold. [1]

  8. 3D printing filament - Wikipedia

    en.wikipedia.org/wiki/3D_printing_filament

    The diameter of the filament is defined by the process that takes place after the plastic has been heated rather than the diameter of the extruder nozzle. A different force and speed is applied to the filament as it is pulled out of the extruder to define the width of the filament, most commonly 1.75 mm or 2.85 mm diameter. [5] [6]

  9. Noryl - Wikipedia

    en.wikipedia.org/wiki/Noryl

    The NORYL family of modified resins consists of amorphous blends of polyphenylene oxides (PPO) or polyphenylene ether (PPE) resins with polystyrene.They combine the inherent benefits of PPE resin (affordable high heat resistance, good electrical insulation properties, excellent hydrolytic stability and the ability to use non-halogen fire retardant packages), with excellent dimensional ...
