HQEE

Hydroquinone bis (2-hydroxyethyl) ether (HQEE)
IUPAC name: 2,2′-(1,4-phenylenebis(oxy)) diethanol
CAS Number: 104-38-2

HQEE is available in off-white flakes, chips and powder form. It is hygroscopic in nature with a strong aromatic odour. To prevent moisture absorption, a desiccant bag is included in the drum. It is also sensitive to light and turns yellow-brown in the presence of light.

HQEE is manufactured industrially by the ethoxylation of hydroquinone. It is a symmetrical aromatic diol chain extender. It offers excellent performance with a wide range of such MDI-prepoIymers and yields polyurethane elastomers that impart good tensile, elongation, hardness, modulus, and a great resistance to mechanical abrasion.

APPLICATIONS:
As a chain extender, HQEE is mainly used to cure TDI/MDI systems, polyurethane products like PU adhesives, coatings, sealants, elastomers, PU foam, spandex and sports ground, etc.
