2-Hydroxyethyl acrylate (2-HEA, CAS 818-61-1) is a bifunctional monomer used as a pendant hydroxyl-bearing unit in the free-radical copolymerization of polycarboxylate ether (PCE) superplasticizers. Its hydroxyl group provides a reactive site for grafting polyethylene glycol side chains onto the polymer backbone, while the acrylate double bond participates directly in radical polymerization. In practical PCE synthesis,

China produces over 85% of global PCE macromonomer output. This guide covers TPEG, HPEG, and EPEG production capacity by province, key manufacturer tiers, molecular weight grade selection, audit checklist, and FOB price benchmarks for procurement teams qualifying Chinese suppliers.

Choosing a PCE superplasticizer supplier in China is only half the job. Before you commit to a long-term contract or lock in a large shipment, a structured factory audit protects you from the two failures that quietly cost concrete admixture buyers the most money: inconsistent solid content batch to batch, and a supplier who cannot

A side-by-side guide to the three regional PCE superplasticizer standards (EN 934-2, ASTM C494, GB 8076) for export procurement and concrete QA teams.

How sodium gluconate works as a concrete retarder, dosage strategies for different climates, PCE compatibility, comparison with other retarders, and sourcing industrial-grade material from China.

Comparison of TPEG, HPEG, and EPEG macromonomer chemistries: copolymerization kinetics, water reduction, slump retention, recipe implications, and application match-up for PCE polymerization.

A practical guide for PCE compounders and procurement teams: specifications, MOQ, sample-to-FCL workflow, payment, logistics, and documentation for buying TPEG/HPEG/EPEG macromonomer direct from a Chinese manufacturer.
