2. Tarpaulin - Wikipedia

   en.wikipedia.org/wiki/Tarpaulin

   An improvised tent using polytarp as a fly Abandoned homeless shelter using plastic tarp. A tarpaulin (/ t ɑːr ˈ p ɔː l ɪ n / tar-PAW-lin, [1] also US: / ˈ t ɑːr p ə l ɪ n / [2]) or tarp is a large sheet of strong, flexible, water-resistant or waterproof material, often cloth such as canvas or polyester coated with polyurethane, or made of plastics such as polyethylene.

3. Polytarp sails - Wikipedia

   en.wikipedia.org/wiki/Polytarp_sails

   The most attractive, durable polytarp sails are usually made from a heavier white polytarp material. Generally, polysails are made from white ultraviolet-protected (UV-protected) material that is 12–16 mils (0.30–0.40 mm) thick (1 mil is .001 inches) and weighs about 6–8 ounces per square yard (200-270 grams per square meter) —about twice the weight and thickness of the common colored ...

4. Polyethylene - Wikipedia

   en.wikipedia.org/wiki/Polyethylene

   Polyethylene absorbs almost no water; the gas and water vapour permeability (only polar gases) is lower than for most plastics. Oxygen, carbon dioxide and flavorings, on the other hand, can pass it easily. Polyethylene burns slowly with a blue flame having a yellow tip and gives off an odour of paraffin (similar to candle flame). The material ...

5. Tar - Wikipedia

   en.wikipedia.org/wiki/Tar

   Tar was used as seal for roofing shingles and tar paper and to seal the hulls of ships and boats. For millennia, wood tar was used to waterproof sails and boats, but today, sails made from inherently waterproof synthetic substances have reduced the demand for tar. Wood tar is still used to seal traditional wooden boats and the roofs of historic ...

6. High-density polyethylene - Wikipedia

   en.wikipedia.org/wiki/High-density_polyethylene

   HDPE is known for its high strength-to-density ratio. [4] The density of HDPE ranges from 930 to 970 kg/m 3. [5] Although the density of HDPE is only marginally higher than that of low-density polyethylene, HDPE has little branching, giving it stronger intermolecular forces and tensile strength (38 MPa versus 21 MPa) than LDPE. [6]

7. Low-density polyethylene - Wikipedia

   en.wikipedia.org/wiki/Low-density_polyethylene

   Low-density polyethylene (LDPE) is a thermoplastic made from the monomer ethylene. It was the first grade of polyethylene , produced in 1933 by John C. Swallow and M.W Perrin who were working for Imperial Chemical Industries (ICI) using a high pressure process via free radical polymerization . [ 1 ]
