WebFeb 13, 2024 · LDPE generally has a lower molecular weight than other plastics, such HDPE. Branching. The branching of the polymer chain in LDPE is another factor that affects its density. The presence of branches in the polymer chain results in a loose, sponge-like structure, which contributes to the low density of the polymer. ... WebThe bottom chain High-Density Polyethylene (HDPE) shows very little branching on the polymer backbone, this gives rise to much shorter, and therefore stiffer and stronger bonds between each molecule. The ability to create a more tightly packed structure gives rise to the higher density, and the strong bonds make the PE hard and opaque, allowing ...

It has branching like LDPE, but the branches are much shorter. LLDPE is produced when ethylene is polymerized with 1-butene, some 1-hexene, and 1-octene. LLDPE has a density range of 0.915 – 0.925 g/cm 3 . LLDPE does have a higher tensile strength than LDPE. dog face on pj'sWebDec 31, 2024 · HDPE is characterized by particularly low levels of side-branching groups on the main polymer chains, and no long side branches at all.
