  2. Polyethylene - Wikipedia

    Since 2008, Japan has increased plastic recycling, but still has a large amount of plastic wrapping which goes to waste. Plastic recycling in Japan is a potential US$90 billion market. [26] It is possible to rapidly convert polyethylene to hydrogen and graphene by heating. The energy needed is much less than for producing hydrogen by electrolysis.

  3. 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]

  4. Renewable polyethylene - Wikipedia

    en.wikipedia.org/wiki/Renewable_Polyethylene

    Green PE has the same properties, performance, and application versatility as fossil-based polyethylene, which makes it a drop-in replacement in the plastic production chain. For these same reasons, it is also recyclable in the same recycling chain used by traditional polyethylene.

  5. Low-density polyethylene - Wikipedia

    en.wikipedia.org/wiki/Low-density_polyethylene

    LDPE has SPI resin ID code 4 Schematic of LDPE branching structure. 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]

  6. Polyethylene terephthalate - Wikipedia

    en.wikipedia.org/wiki/Polyethylene_terephthalate

    PET, like many plastics, is also an excellent candidate for thermal disposal (incineration), as it is composed of carbon, hydrogen, and oxygen, with only trace amounts of catalyst elements (but no sulfur).

  7. Polyolefin - Wikipedia

    en.wikipedia.org/wiki/Polyolefin

    Polypropylene is commonly used in car bumpers, interior trims, and other components [19] where TiO₂ is added to improve the UV stability of the plastic, ensuring that parts do not degrade or lose color when exposed to sunlight over time. [20] Polyethylene films are widely used in agriculture for greenhouses, mulching, and silage wraps. [21]

  8. Top News - Wikipedia

    en.wikipedia.org/wiki/Top_News

    Top News is a 24-hour Albanian television news channel that first aired on February 12, 2007. [2] It is a sister to, and owned by Top Channel, by association its parent company Top Media Group. [1] It is available via the TV provider DigitAlb via terrestrial, satellite, and OTT television.

  9. Expanded polyethylene - Wikipedia

    en.wikipedia.org/wiki/Expanded_polyethylene

    Production of EPE foams is similar to that of expanded polystyrene, but starting with PE beads. [1] Typical densities are 29 to 120 kg/m 3 (49 to 202 lb/cu yd) with the lower figure being common. [1] Densities as low as 14 kg/m 3 (24 lb/cu yd) can be produced. [2]
