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]

3. Polycarbonate - Wikipedia

   en.wikipedia.org/wiki/Polycarbonate

   Other applications, including polycarbonate sheets, may have the anti-UV layer added as a special coating or a coextrusion for enhanced weathering resistance. Polycarbonate is also used as a printing substrate for nameplate and other forms of industrial grade under printed products. The polycarbonate provides a barrier to wear, the elements ...

4. List of commercially available roofing materials - Wikipedia

   en.wikipedia.org/wiki/List_of_commercially...

   Membrane roofing consists of large sheets, generally fused in some way at the joints to form a continuous surface. Cured Thermoset membrane (e.g. EPDM rubber, Neoprene). Synthetic rubber Cured Thermosets are synthetic rubbers that have undergone the vulcanization or "Curing" process. Seams of materials are bonded by adhesives or chemicals ...

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. Lamination - Wikipedia

   en.wikipedia.org/wiki/Lamination

   Laminated fabric are widely used in different fields of human activity, including medical and military. [2]: 148 Woven fabrics (organic and inorganic based) are usually laminated by different chemical polymers to give them useful properties like chemical resistance, dust, grease, photoluminescence (glowing and other light-effects e.g. in high-visibility clothing), tear strength, stiffness ...

7. Greenhouse - Wikipedia

   en.wikipedia.org/wiki/Greenhouse

   Plastics mostly used are polyethylene film and multi-wall sheets of polycarbonate material, or PMMA acrylic glass. Commercial glass greenhouses are often high-tech production facilities for vegetables or flowers.

8. Plastic optical fiber - Wikipedia

   en.wikipedia.org/wiki/Plastic_optical_fiber

   Traditionally, PMMA (acrylic) comprises the core (96% of the cross section in a fiber 1mm in diameter), and fluorinated polymers are the cladding material. Since the late 1990s much higher performance graded-index (GI-POF) fiber based on amorphous fluoropolymer (poly(perfluoro-butenylvinyl ether), CYTOP [1]) has begun to appear in the marketplace.
