Product Description

Polyethylene Glycol Monomethyl Ether (MPEG-2000) Overview

Polyethylene Glycol Monomethyl Ether MPEG-2000 (CAS 9004-74-4) is a water-soluble, non-ionic polymer with a molecular weight of ~2000. As a versatile surfactant and chemical additive, it features excellent emulsifying, dispersing, and lubricating properties. Compatible with most organic/inorganic substances, it offers low toxicity, good stability, and biodegradability. Widely used in coatings, adhesives, textiles, pharmaceuticals, and cosmetics, MPEG-2000 enhances product performance by improving solubility, film-forming ability, and surface activity. Our industrial-grade MPEG-2000 ensures ≥99% purity, consistent quality, and customizable specifications to meet diverse industrial and commercial needs.

Product Advantage

High Stability & Low Toxicity
MPEG-2000 maintains excellent stability under high temperatures and various pH conditions (5.0–7.0). With low toxicity and biodegradability, it meets industrial safety standards, making it suitable for food-contact and pharmaceutical applications. Our product ensures consistent quality with a hydroxyl value range of 26–31 mgKOH/g, verified by strict batch testing.
Superior Solubility & Compatibility
Fully water-soluble and compatible with most organic/inorganic materials, MPEG-2000 dissolves quickly in water, ethanol, and other solvents. This trait simplifies formulation processes in coatings, adhesives, and detergents, reducing production time by 15% compared to similar additives (based on customer feedback).
Versatile Functional Performance
It acts as an efficient emulsifier, dispersant, and lubricant. In construction, it enhances the fluidity of polycarboxylate superplasticizers (its key application); in textiles, it improves fiber softness. Our industrial-grade MPEG-2000 achieves a 99%+ purity rate, ensuring optimal performance in end products.
Customizable Specifications & Reliable Supply
We offer tailored packaging (20kg bags/200kg drums) and adjustable parameters (e.g., hydroxyl value) to meet specific needs. With a 2-year shelf life and stable monthly output of 500 tons, we guarantee on-time delivery for bulk orders, supported by ISO-certified production facilities.

Product Uses

Construction: Polycarboxylate Superplasticizers
MPEG-2000 reacts with acrylic acid to produce MPEG methacrylate, the core monomer for polycarboxylate superplasticizers. These additives improve concrete workability and strength, reducing water consumption by 20–30% in ready-mix concrete, widely used in high-rise buildings and infrastructure projects.
Textiles & Leather: Auxiliaries
As a softener and leveling agent, it enhances fiber flexibility and dye uniformity in textile processing. In leather production, it improves surface smoothness and moisture retention, extending the lifespan of leather products like shoes and bags.
Coatings & Adhesives: Performance Enhancer
It boosts the film-forming ability and stability of water-based coatings, reducing cracking and improving adhesion. In pressure-sensitive adhesives, it maintains wet-tack strength, making it suitable for labels, tapes, and packaging materials.

Product Operate Guide

For most applications: Dissolve MPEG-2000 in water/solvent (ratio 1:5–1:10) under stirring (200–300 rpm) at 25–40°C until fully dissolved. Then add it to the formulation mixture and stir for 10–15 minutes. Adjust the dosage (typically 0.5–5% of total formulation) based on specific product requirements. Store in a dry, ventilated area to avoid moisture.

FAQ

What is the shelf life of MPEG-2000?
It has a 2-year shelf life when stored in sealed packaging in a cool, dry place. Avoid direct sunlight and moisture; opened packages should be resealed promptly to maintain quality.
Can MPEG-2000 be used in food-contact products?
Yes, our low-toxicity MPEG-2000 meets food-grade safety standards (compliant with FDA regulations) when used as a processing aid in food packaging adhesives or coatings.
What is the typical dosage of MPEG-2000 in polycarboxylate superplasticizers?
The dosage is ~30–40% of the superplasticizer formulation (as the monomer raw material). Specific ratios depend on the desired concrete performance (e.g., fluidity, setting time).
