Product Description
HPEG (Hydroxypropyl Polyethylene Glycol Ether), CAS Number: 62601-60-9
HPEG, commonly known as a polycarboxylate ether (PCE) monomer, is a polyether-based macromonomer containing a polymerizable unsaturated group. It is used as a key raw material in the synthesis of polycarboxylate superplasticizers, which improve concrete workability and water-reduction performance. Commercial HPEG grades are available with different molecular weights and ethoxylation characteristics. The exact structure and specifications should be confirmed according to the supplied grade.

Applications of HPEG
HPEG is primarily used as a macromonomer in the production of polycarboxylate ether superplasticizers.
It is used in concrete admixture formulations to help improve cement-particle dispersion, concrete flowability, workability retention, and water-reduction performance.
HPEG-based PCE products are used in ready-mix concrete, precast concrete, high-performance concrete, and other construction applications requiring controlled workability and strength development.
Packaging

35000MT/year.
Storage Requirements
Store HPEG in tightly sealed packaging in a cool, dry, and well-ventilated warehouse. Protect it from moisture, direct sunlight, and excessive heat. Keep packaging closed when not in use to prevent contamination and changes in product quality.
