APEG-1000
Jienuo
Allyl polyethylene glycol APEG-1000 (CAS: 27274-31-3) is a nonionic surfactant with a molecular weight of ~1000. It appears as a white to pale yellow solid, soluble in water and various organic solvents. As a key raw material for polycarboxylate superplasticizers, it endows concrete with high water reduction, excellent dispersion, and good durability, suitable for high-strength (C60+) commercial concrete. It also acts as a chemical intermediate in coatings, papermaking, and modified organosilicon reactions. Non-toxic and non-flammable, it is packaged in plastic drums or woven bags for safe storage and transport.
Product Advantage
High-Performance Superplasticizer Monomer
When used to synthesize polycarboxylate superplasticizers, it delivers a water reduction rate of up to 35% for concrete, significantly improving workability. Its excellent dispersion stability maintains concrete fluidity for over 2 hours, ideal for high-strength (C60+) projects.
Versatile Reactivity
Equipped with an allyl reactive group, it readily participates in double-bond addition reactions, enabling modification of polymers, adhesives, and coatings. This reactivity expands its application in molecular material customization.
Controlled Technical Indexes
With strict parameter control (hydroxyl value 51~62 mgKOH/g, unsaturation ≥0.75 mmol/g), it ensures consistent batch performance, reducing production variability for downstream manufacturers.
Eco-Friendly & Safe
Non-toxic and non-flammable, it poses no corrosion risk to steel bars in concrete. Its environmental compatibility aligns with modern construction's green standards, avoiding pollution in application scenarios.

Product Uses
Polycarboxylate Superplasticizers
It serves as a key raw material for synthesizing high-performance superplasticizers, which are widely used in high-rise buildings, bridges, and precast components. These superplasticizers enhance concrete's strength, durability, and workability.
Polymer Material Modification
Its reactive allyl group enables modification of adhesives, coatings, and plastics, improving their bonding strength, flexibility, and water resistance for industrial and construction materials.
Molecular Material Synthesis
It participates in polymerization reactions to produce functional polymers, applied in fields like water treatment agents and textile auxiliaries, leveraging its surface activity and reactivity.
For superplasticizer synthesis: Mix APEG-1000 with acrylic acid (molar ratio ~1:3) and initiators (e.g., ammonium persulfate) at 80–90℃ for 3–4 hours. For material modification: Blend it with target polymers during processing, controlling the addition amount at 5–10% of the total material weight. Store in a dry, ventilated area; avoid moisture.
FAQ
What is the shelf life of APEG-1000?
It has a 12-month shelf life when stored in sealed packaging in a dry, cool environment. Expired products can still be used if technical indexes (e.g., hydroxyl value) are tested qualified.
Can APEG-1000 be used in low-temperature environments?
Yes, but its solid form may agglomerate below 15℃. Preheating to 25–30℃ before use restores its fluidity without affecting performance.
Is APEG-1000 compatible with other surfactants?
It exhibits good compatibility with most non-ionic and anionic surfactants, but pre-testing is recommended when blending with cationic surfactants to avoid precipitation.
