2. Polycarbonate - Wikipedia

   en.wikipedia.org/wiki/Polycarbonate

   Thermally processed material is usually totally amorphous, [7] and as a result is highly transparent to visible light, with better light transmission than many kinds of glass. Polycarbonate has a glass transition temperature of about 147 °C (297 °F), [8] so it softens gradually above this point and flows above about 155 °C (311 °F). [9]

3. Twinwall plastic - Wikipedia

   en.wikipedia.org/wiki/Twinwall_plastic

   Although single layer polycarbonate sheeting is more flexible than polycarbonate in twinwall configuration, it still retains significant advantages over alternative materials, including glass. A typical 6mm sheet has a density of 0.72 g/cm^2 [ 6 ] and a thermal insulation R value of 0.3 m^2°C/W, while allowing 80% of visible light pass through ...

4. Melt flow index - Wikipedia

   en.wikipedia.org/wiki/Melt_flow_index

   MFI Measuring device. The Melt Flow Index (MFI) is a measure of the ease of flow of the melt of a thermoplastic polymer.It is defined as the mass of polymer, in grams, flowing in ten minutes through a capillary of a specific diameter and length by a pressure applied via prescribed alternative gravimetric weights for alternative prescribed temperatures.

5. Plastic extrusion - Wikipedia

   en.wikipedia.org/wiki/Plastic_extrusion

   A common post-extrusion process for plastic sheet stock is thermoforming, where the sheet is heated until soft (plastic), and formed via a mold into a new shape. When vacuum is used, this is often described as vacuum forming. Orientation (i.e. ability/ available density of the sheet to be drawn to the mold which can vary in depths from 1 to 36 ...

6. Decorative laminate - Wikipedia

   en.wikipedia.org/wiki/Decorative_laminate

   Decorative laminate Roll and sheet of decorative laminate. Decorative laminates are laminated products primarily used as furniture surface materials or wall paneling.It can be manufactured as either high- or low-pressure laminate, with the two processes not much different from each other except for the pressure applied in the pressing process.

7. Bisphenol A - Wikipedia

   en.wikipedia.org/wiki/Bisphenol_A

   It is used as a high performance alternative to polycarbonate. [49] [55] Bisphenol-A formaldehyde resins are a subset of phenol formaldehyde resins. They are used in the production of high-pressure laminates [49] As a minor component. Polyurethane can incorporate BPA and its derivatives as hard segment chain extenders, particularly in memory ...
