i changed the word "ductility" to "resilience"....LDPE does not have a higher ductility than HDPE and any basic materials course in which you measure the tensile strength using a machine will show HDPE plastically deform MUCH more. Resilience...yes. Ductility and toughness? No way.

Should the phrase "recycling number" in the first paragraph be changed to its correct term: "resin identification code"? Should we be using the common terms for things or the correct terms? Nnewton ( talk) 23:22, 10 March 2012 (UTC)
In the general article about polyethylene the melting point range is given, however the melting point is affected by the type of linking. Each article on a specific type of polyethylene, eg Low-density polyethylene, ought to provide its melting point (or more precise range). Anyone know where this information can be found (and how to create an info box)? FreeFlow99 ( talk) 11:32, 27 January 2021 (UTC)
Basic information to add to this article: does it contain phthalates or other estrogenic chemicals? What is its effect on human health, and does it leach chemicals into foods or beverages? Why isn't such information already contained in this article? 173.88.246.138 ( talk) 23:04, 25 July 2021 (UTC)
Currently the chemical resistance section is sourced to a random webpage. Looking at the contents, it's clearly complete garbage. It seriously looks like the resistance ratings there have been randomly generated. It gives "D-Severe Effect" for hexane but "B1-Good" for heptane and "A-Excellent" for gasoline, which is highly implausible. And it gives "D-Severe Effect" for citric acid, "Mayonnaise", and "Detergents", which is just ridiculous. We need to find an actual reference to source this section to. 73.170.147.86 ( talk) 03:26, 12 August 2021 (UTC)
