Low Dosage · High Water Reduction · High Performance for Modern Concrete
Product Introduction
Our High-Efficiency TPEG (Isopentenol Polyoxyethylene Ether) Polycarboxylate Ether Monomer is the core raw material for manufacturing high-performance polykarboxylat supermjukgörare. With its unique comb-like molecular structure, it delivers exceptional performance in concrete admixtures, becoming the first choice for high-end concrete projects globally. It is non-toxic, environmentally friendly, and fully compliant with international concrete material standards, providing reliable support for your high-quality concrete production.
Core Advantages: Low Dosage & High Water Reduction
Ultra-Low Dosage, Cost-Saving
- Recommended dosage is only 0.15%–0.3% of cementitious materials, far lower than traditional naphthalene-based or aliphatic superplasticizer monomers.
- For 20% solid-content polykarboxylat supermjukgörare mother liquor, a dosage of 1.0% (relative to cement) can achieve excellent fluidity and workability of concrete.
- Significantly reduces the consumption of admixtures, lowers the overall cost of concrete production, and improves economic benefits for enterprises.
Ultra-High Water Reduction, Superior Performance
- Water reduction rate reaches 26%–35%, and can be as high as 38%–40% with high-efficiency formulations, effectively reducing the water-cement ratio of concrete.
- Dual mechanism guarantee: Electrostatic repulsion of anionic carboxyl groups and steric hindrance of long polyoxyethylene (EO) side chains prevent cement particle flocculation, ensuring excellent fluidity.
- The hydration film formed by side chains enhances lubrication, making concrete easier to mix, pump and pour.

Synthesis & Wide Applications
Synthesis Principle
TPEG copolymerizes with unsaturated monomers (acrylic acid, methacrylic acid, maleic anhydride, etc.) via free-radical polymerization to form comb-shaped polykarboxylat supermjukgörare polymers, which are the key to high-performance concrete admixtures.
Main Application Fields
- High-Strength/High-Performance Concrete (HPC): Suitable for bridges, tunnels, high-rise buildings, and other large-scale key projects that require high strength and durability.
- Pumping Concrete: Ideal for long-distance transportation and large-volume pouring, ensuring stable fluidity and no slump loss during construction.
- Precast Concrete: Facilitates quick demolding of prefabricated components, improves production efficiency, and ensures the surface quality of components.
- Special Concrete: Applicable to self-compacting concrete (SCC), underwater concrete, and other special engineering concrete, meeting diverse construction needs.
Additional Superior Properties
- Excellent Slump Retention: Minimal slump loss within 1–2 hours, suitable for construction in hot weather and long-distance delivery.
- Good Compatibility: Strong adaptability to various cements, fly ash, slag, and other mineral admixtures, no adverse reactions.
- Environmentally Friendly: No formaldehyde, low chloride and sulfate content, non-corrosive to steel reinforcement, in line with global environmental protection requirements.
- Enhanced Durability: Reduces the water-cement ratio of concrete, significantly improving the compressive strength, impermeability, and frost resistance of concrete, extending the service life of projects.
