APEG-2200
Jienuo
Allyl polyethylene glycol APEG-2200 (CAS 27274-31-3) is a high-purity, non-ionic surfactant and polymer monomer. As a key raw material for polycarboxylate superplasticizers, it enhances concrete workability and strength by acting as a cement dispersant. Water-soluble and low-impurity, it suits industrial applications in construction chemicals. It also functions as a reactive intermediate in polymerization, enabling the synthesis of water-based polymers. Ideal for manufacturers of concrete additives, it balances performance and compatibility in construction material formulations.
Product Advantage
Controlled Technical Specifications
APEG-2200 maintains strict quality parameters: hydroxyl value (24–28 mgKOH/g) and unsaturation (≥0.34 mmol/g) ensure stable reactivity in polymerization. Its low-impurity, non-ionic structure enables excellent compatibility with other additives, reducing formulation errors for manufacturers.
Superior Performance in Concrete Additives
When used in polycarboxylate superplasticizers, it delivers strong cement dispersion: concrete mixed with APEG-2200-based additives shows 30% higher workability and 15% improved strength retention (vs. generic monomers), per lab tests.
Versatile Reactivity
Its allyl-terminated structure enables efficient copolymerization with unsaturated monomers (e.g., acrylic acid), supporting the synthesis of water-soluble polymers for multiple industrial scenarios. This flexibility cuts R&D costs for downstream product development.
Stable Physical Form & Storage
Supplied as easy-to-handle flakes (20kg bags), APEG-2200 has a 12-month shelf life under dry, ventilated conditions—reducing storage waste and logistics complexity for bulk buyers.

Product Uses
Polycarboxylate Superplasticizers for Concrete
It is a core raw material for high-performance polycarboxylate superplasticizers, used in ready-mix concrete and high-strength (C80+) precast components. These additives enhance concrete workability, reduce water consumption, and improve durability in infrastructure projects.
Water-Soluble Polymer Synthesis
APEG-2200 acts as a reactive intermediate to produce water-based polymers, applicable in textile auxiliaries, oilfield chemicals, and coating additives—extending its utility beyond construction.
To use APEG-2200 in superplasticizer production: Mix it with acrylic acid (molar ratio 1:3–1:5) in a reactor; heat to 80–90℃, add initiators (e.g., ammonium persulfate), and react for 3–4 hours. Cool to room temperature before blending with other additives. Ensure proper ventilation during operation.
FAQ
What is the shelf life of APEG-2200?
It has a 12-month shelf life when stored in dry, ventilated areas (avoid moisture). Expired products can be tested for hydroxyl/unsaturation values before use.
Can APEG-2200 be used in low-temperature environments?
Yes—its flake form remains stable at 0–5℃, but pre-heating (to 20–25℃) eases mixing during cold-weather production.
Is APEG-2200 compatible with other monomers?
It works well with acrylic acid, maleic anhydride, and vinyl monomers, with compatibility confirmed in 90% of industrial formulation tests.
