MPEG2200: High Water-Reduction Polyether Monomer
MPEG / Methoxy Polyethylene Glycol
MPEG is used as a raw material of concrete admixtures. Admixtures with MPEG reduce water content by more than 30%, through which the strength of concrete is improved. EVERSTAR MPEG is a high-purity product with low Diol content.
Engineered for Maximum Water Reduction (25-40%)
- Mechanism: Long PEO side chains enhance steric hindrance, improving cement dispersion efficiency by 30%
- Sustainability: Reduces cement consumption by 80-120kg/m³, lowering CO₂ emissions by 18%
