The thread used to stitch modern marine type canvas is typically made from Polyester or PTFE with sizes ranging from #69, #92, #138. [8] Polyester thread is widely available and relatively low cost compared to PTFE, but PTFE thread has become increasingly popular due to its far greater resistance to ultraviolet radiation a chemical ...
More recent studies have found that more than half of plastic debris found on Korean shores is ocean-based. [7] A wide variety of man-made objects can become marine debris; plastic bags, balloons, buoys, rope, medical waste, glass and plastic bottles, cigarette stubs, cigarette lighters, beverage cans, polystyrene, lost fishing line and nets ...
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.
Waterproof packaging or other types of protective cases for electronic devices can be found. A new technology enabled the release of various waterproof smartphones and tablets in 2013. [6] A study from 2013 found that nano-textured surfaces using cone shapes produce highly water-repellent surfaces. These "nanocone" textures are superhydrophobic ...
Green and white sea glass. Sea glass are naturally weathered pieces of the anthropogenic glass fragments of typically drinkwares, which often have the appearance of tumbled stones. Sea glass is physically polished and chemically weathered glass found on beaches along bodies of salt water. These weathering processes produce natural frosted glass ...
Water-repellent glass (WRG) is a transparent coating film fabricated onto glass, enabling the glass to exhibit hydrophobicity and durability. [1] WRGs are often manufactured out of materials including derivatives from per- and polyfluoroalkyl substances (PFAS), tetraethylorthosilicate (TEOS), polydimethylsilicone (PDMS), and fluorocarbons .

The coating can be sprayed onto objects to make them waterproof. The spray is anti-corrosive and anti-icing; has cleaning capabilities; and can be used to protect circuits and grids. Superhydrophobic coatings have important applications in maritime industry. They can yield skin friction drag reduction for ship hulls, thus increasing fuel ...
