2. Polycarbonate - Wikipedia

   en.wikipedia.org/wiki/Polycarbonate

   The main polycarbonate material is produced by the reaction of bisphenol A (BPA) and phosgene COCl 2. The overall reaction can be written as follows: The first step of the synthesis involves treatment of bisphenol A with sodium hydroxide, which deprotonates the hydroxyl groups of the bisphenol A. [6] (HOC 6 H 4) 2 CMe 2 + 2 NaOH → Na 2 (OC 6 ...

   This is done by feeding a welding rod into the weld gun nozzle and heating the vinyl and the welding rod along the gap between two vinyl tiles. Cross-section contrasting, left, a conventional floor; center, a bathtub floor of the sort used for wetrooms, with an impermeable sheet floor sealed (in red) to an impermeable wall covering; right, a ...

4. Poly(methyl methacrylate) - Wikipedia

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

   PMMA is an important material in the making of certain lighthouse lenses. [31] PMMA was used for the roofing of the compound in the Olympic Park for the 1972 Summer Olympics in Munich. It enabled a light and translucent construction of the structure. [32] PMMA (under the brand name "Lucite") was used for the ceiling of the Houston Astrodome.

5. Polyvinyl chloride - Wikipedia

   Vinyl gloves. Plasticized PVC is a common material for medical gloves. Due to vinyl gloves having less flexibility and elasticity, several guidelines recommend either latex or nitrile gloves for clinical care and procedures that require manual dexterity or that involve patient contact for more than a brief period. Vinyl gloves show poor ...

6. Vinyl polymer - Wikipedia

   en.wikipedia.org/wiki/Vinyl_polymer

   Vinyl polymers are subject of several structural variations, which greatly expands the range of polymers and their applications. With the exception of polyethylene, vinyl polymers can arise from head-to-tail linking of monomers, head-to-head combined with tail-to-tail, or a mixture of those two patterns. Additionally the substituted carbon center in such polymers is stereogenic (a "chiral center")

7. Ethylene-vinyl acetate - Wikipedia

   en.wikipedia.org/wiki/Ethylene-vinyl_acetate

   The EVA copolymer which is based on a medium proportion of VA (approximately 4 to 30%) is referred to as thermoplastic ethylene-vinyl acetate copolymer and is a thermoplastic elastomer material. It is not vulcanized but has some of the properties of a rubber or of plasticized polyvinyl chloride particularly at the higher end of the range.

8. Polyvinyl acetate - Wikipedia

   The stiff homopolymer PVAc, but mostly the softer copolymer, a combination of vinyl acetate and ethylene, vinyl acetate ethylene (VAE), is also used in paper coatings, paint and other industrial coatings, as a binder in nonwovens in glass fibers, sanitary napkins, filter paper and in textile finishing.

9. Vacuum insulated panel - Wikipedia

   en.wikipedia.org/wiki/Vacuum_insulated_panel

   A vacuum insulated panel (VIP) is a form of thermal insulation consisting of a gas-tight enclosure surrounding a rigid core, from which the air has been evacuated. It is used in building construction , refrigeration units, and insulated shipping containers to provide better insulation performance than conventional insulation materials.
