2. Polycarbonate - Wikipedia

   en.wikipedia.org/wiki/Polycarbonate

   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 chemical properties it is not conducive to laser-cutting.

3. Plastic optical fiber - Wikipedia

   en.wikipedia.org/wiki/Plastic_optical_fiber

   Plastic optical fiber (POF) or polymer optical fiber is an optical fiber that is made out of polymer. Similar to glass optical fiber , POF transmits light (for illumination or data) through the core of the fiber.

4. Sheet moulding compound - Wikipedia

   The sheets are compacted and then enter onto a take-up roll, which is used to store the product whilst it matures. The carrier film is then later removed and the material is cut into charges. Depending on what shape is required determines the shape of the charge and steel die which it is then added to.

5. Polyol - Wikipedia

   en.wikipedia.org/wiki/Polyol

   Polycarbonate polyols are more expensive than other polyols and are thus used in more demanding applications. [31] [32] They have been used to make an isophorone diisocyanate based prepolymer which is then used in glass coatings. [33] They may be used in reactive hotmelt adhesives. [34] All polyols may be used to produce polyurethane prepolymers.

6. Film capacitor - Wikipedia

   en.wikipedia.org/wiki/Film_capacitor

   In a suitable evaporation system and under high vacuum conditions (about 10 15 to 10 19 molecules of air per cubic meter) the plastic film is metallized with aluminum or zinc. It is then wound onto a so-called "mother roll" with a width of about 1 meter.

7. Poly(methyl methacrylate) - Wikipedia

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

   Sheets of PMMA are commonly used in the sign industry to make flat cut out letters in thicknesses typically varying from 3 to 25 millimeters (0.1 to 1.0 in). These letters may be used alone to represent a company's name and/or logo, or they may be a component of illuminated channel letters.
