What is Hydroquinone bis(2-hydroxyethyl) ether?

Hydroquinone bis(2-hydroxyethyl) ether (CAS 104-38-1), commonly known as HQEE, is a difunctional diol used as a chain extender and reactive intermediate in polymer systems. Also known as 1,4-Bis(2-hydroxyethoxy)benzene.

Where is Hydroquinone bis(2-hydroxyethyl) ether used?

  • Cast polyurethane elastomers: chain extender improving hardness, load-bearing capacity and thermal resistance in industrial wheels, rollers and mining screens
  • Polyurethane and polyester materials: aromatic diol building block for rigid, high-performance products
  • Printing and packaging: high-durability inks and coatings requiring chemical resistance
  • Personal care: film-forming systems and specialty polymer bases
  • Polyester synthesis: reactive diol for industrial resins, its aromatic backbone raising the glass transition temperature of the final resin
  • It is essential for heavy-duty industrial components.

Commercial specifications

  • Purity specifications commonly at 99% or higher
  • Packaging generally in bags and drums suited to industrial-scale procurement
