Materials for synthetic fibers
Mitsubishi Chemical offers poly(tetramethylene ether)glycol (PTMG) and ethylene glycol that are used as raw materials for Spandex (polyurethane elastic fibers) and polyester fibers. We supply poly(tetramethylene ether)glycol (PTMG) with wide selection of molecular weights from 650 to 3000. *MCC PTA Asia Pacific Pte. Ltd. sells terephthalic acid, a raw material for polyester.
Monoethylene glycol is one of the main raw materials for polyethylene terephthalate (PET resin). It is widely used for automotive antifreeze solutions because the freezing point is low, toxicity is low, and it is completely miscible in water. CAS: No. 107-21-1 EINECS: No. 203-473-3 Japan, Chemical Substances Control Law: METI-No. 2-230 Japan, Fire Services Law: Hazardous material Class 4 Petroleums No. 3 (water-soluble liquid).
PTMG (Poly(tetramethylene ether)glycol / PTMG) is a linear polyether glycol with hydroxyl groups on both ends. As a polyol, it reacts readily with isocyanates (for example MDI, TDI), etc. to make resins with excellent properties.
