Unmatched Synthesis Yield (≥98.74% Double Bond Retention): Utilizing a high-activity catalyst and an advanced synthesis process, our HPEG guarantees an ultra-high chemical conversion rate. This prevents unreacted monomers, maximizing your PCE mother liquor yield while slashing production costs.
Outstanding Water Reduction: The PCE mother liquor synthesized from our HPEG delivers a 30%–35% water-reducing rate at just 20% solid content and a low dosage of 1.0% (by weight of cementitious material).
Early & Long-term Strength Enhancement: Significantly boosts concrete compressive strength across all stages: 1 Day ≥180%, 3 Days ≥170%, 28 Days ≥150%.
Eco-Friendly Compliance: Formulated without formaldehyde or chloride ions, ensuring low sulfate content to easily clear strict local environmental audits.
Description
Our HPEG (Hydroxy Polyethylene Glycol Monoallyl Ether) is a premium-grade polycarboxylate macromonomer derived from TPEG, engineered specifically for the synthesis of high-performance Polycarboxylate Ether (PCE) superplasticizers.
By copolymerizing our HPEG monomer with acrylic acid, you can manufacture high-efficiency concrete admixtures that feature exceptional water solubility, superior cement adaptability, and excellent slump retention. It is widely used in ready-mix concrete, precast concrete, and high-performance infrastructure projects.

Why EAST CHEM?
Pain Point 1: Low conversion rate & high chemical waste in your PCE synthesis.
Our Solution: Lower-grade monomers lead to incomplete polymerization. Our HPEG provides a certified 98.74% double bond retention and narrow molecular weight distribution, drastically lowering your raw material consumption per ton of finished PCE.
Pain Point 2: Poor concrete slump retention causing site complaints.
Our Solution: Our highly active macromonomer delivers precise chemical configuration. The resulting PCE keeps concrete highly plastic with a slump retention index ≥190mm, showing negligible slump loss after 1 hour—perfect for hot-weather transit.
Pain Point 3: Import risks, customs delays, and unstable chemical suppliers.
Our Solution: EAST CHEM brings 13+ years of fine chemical export expertise servicing top buyers in India, Japan, South Korea, the USA, Russia, and the UAE. We provide flawless customs documentation, complete MSDS/COA sheets, and stable bulk supply chains.
Packaging & Storage
Standard Packaging: 25kg/bag. Secure industrial moisture-proof packaging suitable for ocean freight.
Storage Conditions: Nontoxic, tasteless, and nonflammable. Store as a general chemical in a cool, dry, and well-ventilated warehouse.
