PTMEG is a polyether glycol used as a key raw material in spandex production. Because spandex demand absorbs a large share of PTMEG consumption, users often read PTMEG, BDO, MDI, and spandex fiber pages together.
BDO can be used to produce PTMEG, while PTMEG and MDI are key raw materials in spandex production. Reading these raw material pages together with the spandex page helps users understand which parts of the chain are upstream feedstocks and which are downstream fiber markets.
