  2. 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 ...

  3. Linear low-density polyethylene - Wikipedia

    en.wikipedia.org/.../Linear_low-density_polyethylene

    During a shearing process, such as extrusion, LLDPE remains more viscous and, therefore, harder to process than an LDPE of equivalent melt index. The lower shear sensitivity of LLDPE allows for a faster stress relaxation of the polymer chains during extrusion, and, therefore, the physical properties are susceptible to changes in blow-up ratios.

  4. Renewable polyethylene - Wikipedia

    en.wikipedia.org/wiki/Renewable_Polyethylene

    One of the main environmental benefits of Green PE is the sequestration of roughly 2.15 tonnes of CO 2 per tonne of Green Polyethylene produced, which comes from the CO 2 absorbed by the sugar cane while growing, minus the CO 2 emitted through the production process. Renewable polyethylene is non-biodegradable and can be recycled in the same ...

  5. Ethylene - Wikipedia

    en.wikipedia.org/wiki/Ethylene

    Ethylene (IUPAC name: ethene) is a hydrocarbon which has the formula C 2 H 4 or H 2 C=CH 2.It is a colourless, flammable gas with a faint "sweet and musky" odour when pure. [7] It is the simplest alkene (a hydrocarbon with carbon–carbon double bonds).

  6. High-density polyethylene - Wikipedia

    en.wikipedia.org/wiki/High-density_polyethylene

    In a similar way, the Phillips slurry process uses silica-based catalysts in contact with a fast-moving hydrocarbon and polyethylene slurry to precipitate high density polyethylene. [18] Processing will determine the properties of the HDPE. The method used to synthesize the HDPE is crucial because the micro structure of the HDPE will vary.

    The United States Food and Drugs Administration is warning pet owners about a common medication given to pets to treat arthritis. The F.D.A. now says that the drug Librela may be associated with ...

  8. Polyethylene glycol - Wikipedia

    en.wikipedia.org/wiki/Polyethylene_glycol

    Polyethylene glycol is also commonly used as a polar stationary phase for gas chromatography, as well as a heat transfer fluid in electronic testers. PEG is frequently used to preserve waterlogged wood and other organic artifacts that have been salvaged from underwater archaeological contexts, as was the case with the warship Vasa in Stockholm ...
