2. Linear low-density polyethylene - Wikipedia

   en.wikipedia.org/wiki/Linear_low-density...

   Linear low-density polyethylene differs structurally from conventional low-density polyethylene (LDPE) because of the absence of long chain branching. The linearity of LLDPE results from the different manufacturing processes of LLDPE and LDPE. In general, LLDPE is produced at lower temperatures and pressures by copolymerization of ethylene and ...

3. 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]

4. Bubble wrap - Wikipedia

   en.wikipedia.org/wiki/Bubble_wrap

   Bubble wrap Square-shaped bubble wrap for house insulation. Bubble wrap is a pliable transparent plastic material commonly used for protecting fragile items during shipping. . Known for its cushioning air-filled bubbles, it has also become a cultural icon, celebrated for its satisfying popping sound and alternative uses as a stress-relief

5. Stretch wrap - Wikipedia

   en.wikipedia.org/wiki/Stretch_wrap

   The most common stretch wrap material is linear low-density polyethylene (LLDPE), which is produced by copolymerization of ethylene with alpha-olefins, the most common of which are butene, hexene and octene.

6. Polyethylene - Wikipedia

   en.wikipedia.org/wiki/Polyethylene

   The plastic type which releases gases at the highest rate is low-density polyethylene (LDPE). Due to its low density it breaks down more easily over time, leading to higher surface areas. When incubated in air, LDPE emits gases at rates ~2 times and ~76 times higher in comparison to incubation in water for methane and ethylene, respectively.

7. Cross-linked polyethylene - Wikipedia

   en.wikipedia.org/wiki/Cross-linked_polyethylene

   A cross-linked polyethylene (PEX) pipe. Cross-linked polyethylene, commonly abbreviated PEX, XPE or XLPE, is a form of polyethylene with cross-links.It is used predominantly in building services pipework systems, hydronic radiant heating and cooling systems, domestic water piping, insulation for high tension (high voltage) electrical cables, and baby play mats.
