===Industrial uses===
* A [[nitrate]] [[ester]]-plasticized polyethylene glycol ([[Solid-fuel rocket#Composite modified double base propellants|NEPE-75]]) is used in [[UGM-133 Trident II#Design|Trident II]] [[submarine-launched ballistic missile]] solid rocket fuel.<ref name="Spinardi-1994">{{cite book| vauthors = Spinardi G |title=From Polaris to Trident: the development of US fleet ballistic missile technology|url=https://archive.org/details/frompolaristotri00spin_389|url-access=limited|year=1994|publisher=Cambridge Univ.

* Dimethyl ethers of PEG are the key ingredient of [[Selexol]], a solvent used by [[coal]]-burning, [[integrated gasification combined cycle]] (IGCC) power plants to remove [[carbon dioxide]] and [[hydrogen sulfide]] from the [[syngas]] stream.
* PEG has been used as the gate insulator in an electric double-layer transistor to induce superconductivity in an insulator.<ref>{{cite journal | vauthors = Ueno K, Nakamura S, Shimotani H, Ohtomo A, Kimura N, Nojima T, Aoki H, Iwasa Y, Kawasaki M | display-authors = 6 | title = Electric-field-induced superconductivity in an insulator | journal = Nature Materials | volume = 7 | issue = 11 | pages = 855–8 | date = November 2008 | pmid = 18849974 | doi = 10.1038/nmat2298 | bibcode = 2008NatMa...7..855U }}</ref>
* PEG is used as a polymer host for solid polymer electrolytes. Although not yet in commercial production, many groups around the globe are engaged in research on solid polymer electrolytes involving PEG, to improve their properties, and in permitting their use in batteries, electro-chromic display systems, and other products in the future.
* PEG is injected into industrial processes to reduce foaming in separation equipment.
* PEG is used as a [[Binder (material)|binder]] in the preparation of technical [[ceramic]]s.<ref>Schneider, Samuel J. (1991) ''Engineered Materials Handbook: Ceramics and Glasses'', Vol. 4. ASM International. {{ISBN|0-87170-282-7}}. p. 49.</ref>
* PEG was used as an additive to silver halide photographic [[Photolith film|emulsions]].
* PEG is used as an active ingredient in agricultural soil wetter, which improves water-retention and seedling growth.<ref>{{cite web |title=4Farmers Aquifer Infosheet |url=https://4farmers.com.au/products/plant-health/aquifer/ |website=4farmers.com.au |publisher=4Farmers Australia |access-date=6 February 2025}}</ref>
