Product Overview
SPS-28 is a new-generation, environmentally friendly high-performance polycarboxylate ether (PCE) superplasticizer in flake form.
Developed using EPEG-3000 as the primary raw material through optimized side-chain conformation and low-temperature free-radical copolymerization, SPS-28 achieves exceptional dispersion and stable slump retention through the synergistic action of steric hindrance and electrostatic repulsion.
This fully water-soluble, high-solid-content flake represents the latest advancement in solid PCE technology-delivering performance that matches or exceeds liquid superplasticizers while offering unparalleled logistics and handling advantages
Advantages
SPS-28 Water Reducing Polycarboxylate Superplasticizer Flake
✅ Ultra-High Water Reduction
-Achieves water reduction rates of ≥25%
-with a solid content of ≥97%.
-Low dosage (0.2%–0.5% by mass of cementitious materials) delivers exceptional dispersing performance
✅ Complete Water Solubility – Zero Residue
Dissolves rapidly and completely in water, forming a uniform, clear, and stable solution with no precipitation or residue.
No complex mixing equipment required-simply add to the mixing system either as a dry blend or pre-dissolved solution
