Product Description

Allyl Polyethylene Glycol APEG-900 (CAS 27274-31-3) Overview

Allyl polyethylene glycol APEG-900 (CAS 27274-31-3) is a key allyl-terminated polyether monomer with a molecular weight of ~900. It features good water solubility, reactivity (via its allyl group), and compatibility with other monomers. Primarily used as a macromonomer in synthesizing polycarboxylate superplasticizers (for concrete), it enhances cement dispersion and workability. It also finds applications in coatings, adhesives, and textile auxiliaries, acting as a reactive modifier to improve product performance (e.g., adhesion, flexibility).

Product Advantage

High Reactivity & Performance Stability
With an unsaturation ≥0.90 mmol/g, APEG-900 enables efficient polymerization with acrylic acid to synthesize polycarboxylate superplasticizers. Its consistent hydroxyl value (56~70 mgKOH/g) ensures stable dispersion of cement particles, maintaining concrete workability for over 2 hours—critical for long-distance concrete transportation.
Eco-Friendly & Cost-Effective
Derived APEG-900 superplasticizers reduce cement usage by 10–15% while boosting concrete strength (C60+). They are non-toxic, non-corrosive to steel reinforcement, and meet environmental standards, cutting both material costs and project carbon footprints.
Versatile Compatibility
Soluble in water and most organic solvents, APEG-900 integrates well with other monomers (e.g., sodium methallyl sulfonate) for custom polymer formulations. This flexibility supports applications in coatings, adhesives, and textile auxiliaries, improving product adhesion and flexibility.
Strict Quality Consistency
Manufactured with controlled technical indices (e.g., pH, unsaturation), APEG-900 ensures batch-to-batch uniformity. This reliability minimizes production variations in downstream products (e.g., superplasticizers), enhancing end-user operational efficiency.

Product Uses

Concrete Superplasticizers
APEG-900 is the primary raw material for polycarboxylate superplasticizers, used in high-strength (C60+) commercial concrete. These additives reduce water-cement ratios by 20–30%, improving concrete flowability for on-site mixing and long-distance pumping (e.g., high-rise buildings, bridges).
Coatings & Adhesives
As a reactive modifier, APEG-900 enhances coating adhesion and flexibility. It copolymerizes with acrylic monomers to form water-based coatings with better weather resistance, suitable for architectural and industrial protective coatings.
Textile Auxiliaries
APEG-900 acts as a dispersant in textile dyeing, ensuring uniform color distribution. It also modifies textile finishing agents to improve fabric softness and wash resistance, widely used in polyester and cotton processing.

Product Operate Guide

For superplasticizer synthesis: Dissolve APEG-900 (20–30% w/w) in deionized water at 60–70°C. Add acrylic acid and initiators (e.g., ammonium persulfate) dropwise over 2–3 hours, then cure at 80°C for 1 hour. Cool and adjust pH to 6–7 with NaOH. Store the product in dry, ventilated areas (shelf life: 1 year).

FAQ

Q: What is APEG-900's storage condition?
A: Store in sealed plastic drums (200kg) or woven bags (20kg) in dry, ventilated areas (temperature 5–30°C). Avoid moisture; shelf life is 12 months.
Q: Can APEG-900 replace APEG-800 in formulations?
A: Yes, but adjust dosage slightly (APEG-900's higher molecular weight may require 5–10% less usage) to maintain superplasticizer performance consistency.
Q: Is APEG-900 safe for construction workers?
A: Yes, it is non-toxic and non-irritating to skin (pH 5.0–7.0). Follow standard chemical handling protocols (gloves, goggles) during operation.
