Product Description

Allyl Polyethylene Glycol APEG-500 (CAS 27274-31-3) Overview

Allyl polyethylene glycol APEG-500 (CAS 27274-31-3), also called allyl-terminated PEG 500 or polyethylene glycol allyl ether 500, is a versatile industrial chemical. As a hydrophilic allyl-functional polymer, it acts as a reactive monomer in polymerization processes (e.g., for superplasticizers in concrete) and a modifier in coatings, adhesives, and textile chemicals. It offers good compatibility, stable performance, and adjustable reactivity, making it widely used in construction, chemical synthesis, and material processing industries. Reliable suppliers typically provide high-purity grades for consistent application results.

Product Advantage

High Reactivity & Purity
Boasting ≥1.75 mmol/g unsaturation and stable hydroxyl groups, APEG-500 enables efficient copolymerization reactions. Its strict quality control ensures consistent performance (pH 5.0–7.0, 99% purity), reducing production variability for manufacturers.
Excellent Compatibility
Fully soluble in water and polar solvents, this product integrates seamlessly into diverse formulations (e.g., concrete admixtures). Its low viscosity (liquid form) simplifies handling and blending in industrial processes.
Superior Dispersion Performance
When used in polycarboxylate superplasticizers, APEG-500 delivers long-lasting concrete fluidity—extending workability by 60% vs. conventional materials, critical for high-strength (C60+) concrete projects.
Cost-Effective Stability
With a 12-month shelf life (stored in dry, ventilated areas), APEG-500 minimizes material waste. Its 200kg/drum packaging supports bulk industrial use while lowering logistics costs per unit.

Product Uses

Polycarboxylate Superplasticizers
As a core raw material for high-performance superplasticizers, APEG-500 enhances concrete's fluidity and slump retention. It is widely applied in precast, high-strength (C60+) concrete for on-site casting and long-distance transportation.
Polymer Modification
Its reactive double bond enables grafting with silicone or fluorocarbon resins, improving polymer materials' dispersion and compatibility. It is used in coatings, textiles, and papermaking additives.

Product Operate Guide

APEG-500 is typically added during the copolymerization stage of formulations (e.g., superplasticizers) at 10–20% dosage (based on total raw materials). Blend it with water or polar solvents first, then mix with other monomers under stirring (25–30°C) for 30–60 minutes to ensure uniform dispersion.

FAQ

What is APEG-500's shelf life?
It has a 12-month shelf life when stored in dry, ventilated areas (avoiding moisture and direct sunlight). Unsealed packages should be used within 30 days to maintain performance.
Is APEG-500 safe to handle?
It is non-flammable and non-toxic (general chemical). Avoid direct contact with eyes; rinse with water if exposed. Follow standard industrial handling protocols.
Can it be used in low-temperature environments?
As a liquid product, APEG-500 remains workable at ≥5°C. For cold regions, store it in heated warehouses (10–25°C) to prevent viscosity increase.
