2. 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. [7]

   Isomers of the repeating unit in polyaspartic acid.. Polycarboxylates are used as builders in detergents. [2] Their high chelating power, even at low concentrations, reduces deposits on the laundry and inhibits the crystal growth of calcite.

7. Sandwich panel - Wikipedia

   en.wikipedia.org/wiki/Sandwich_panel

   Sandwich panels are used in applications where a combination of high structural rigidity and low weight is required. The structural functionality of a sandwich panel is similar to the classic I-beam , where two face sheets primarily resist the in-plane and lateral bending loads (similar to flanges of an I- beam), while the core material mainly ...
