Product Advantage
High Reactivity & Functional Versatility
APEG-400 features allyl groups that enable efficient copolymerization with unsaturated monomers (e.g., acrylic acid). Its hydroxyl value (101–125 mgKOH/g) ensures stable bonding, making it a reliable building block for modified polymers and high-performance additives.
Excellent Compatibility & Solubility
As a water-soluble (and multi-solvent-soluble) non-ionic polymer, it mixes seamlessly with most construction, textile, and coating formulations. Its pale yellow liquid form (25°C) allows easy handling and uniform blending in production.
Strict Quality Consistency
Our APEG-400 meets standardized technical benchmarks (pH 5.0–7.0, water insolubility ≥2.10 mmol/g), with batch-to-batch stability verified by industrial-grade testing—ideal for large-scale manufacturing.
Multi-Scenario Adaptability
Beyond construction, its thermal stability and reactivity suit applications in emulsifiers, textile auxiliaries, and polymer modifiers, delivering consistent performance across diverse industrial processes.

Product Uses
Polycarboxylate Superplasticizer Raw Material
It is a core monomer for polycarboxylate superplasticizers in construction. When polymerized, it enhances concrete's workability, reduces water usage, and boosts strength (suitable for C600+ high-performance concrete in large projects like bridges).
Polymer Modifier & Co-monomer
Its allyl groups enable copolymerization with unsaturated compounds, used to modify adhesives, coatings, and high-molecular materials—improving product bonding and durability.
Industrial Additive
Serves as an emulsifier in detergents, a solubilizer in textile auxiliaries, and a compatibility agent in coating formulations, enhancing product functionality and stability.
For superplasticizer production: Mix APEG-400 with acrylic acid (molar ratio adjusted per formula) in a reactor; heat to 70–80°C, add initiators (e.g., ammonium persulfate), and react for 3–4 hours. Stir uniformly during blending to ensure full polymerization. Store the finished product in sealed containers at room temperature.
FAQ
What is the shelf life of APEG-400?
It has a 12-month shelf life when stored in a dry, ventilated area (avoid direct sunlight). Sealed packaging prevents moisture contamination, which could affect its hydroxyl value.
Is APEG-400 suitable for high-temperature processes?
Yes, it maintains thermal stability in typical industrial reaction temperatures (≤100°C), so it can be safely used in polymerization or blending processes under standard operating conditions.
Can APEG-400 be mixed with other surfactants?
As a non-ionic polymer, it is compatible with most anionic/cationic surfactants. Test small batches first to confirm blending effects before large-scale use.
