Description

Poly(Oxy-1,2-Ethanediyl), α-Hydro-ω-Hydroxy-, Ether With 1,3-Benzenediol (Mittlere Molmasse 700 G/Mol) is a specialized, low molecular weight polyethylene glycol (PEG) derivative of hydroquinone, designed for use as a reactive intermediate and functional additive. This product is valued for its dual functionality, combining the hydrophilic, solubilizing properties of PEG with the antioxidant and polymerizable characteristics of the aromatic diol. It is primarily needed by formulators and chemical manufacturers in the polymer, coatings, and specialty chemical industries seeking to modify material properties or synthesize advanced macromolecules.

Application

• Polymer Modification: Acts as a chain extender or cross-linking agent in polyurethane and epoxy resin synthesis.
• Surface Coatings: Used as a hydrophilic modifier in coatings to improve wetting, dispersion, and adhesion properties.
• Specialty Additives: Serves as an intermediate for synthesizing antioxidants, UV stabilizers, and other performance additives.
• Pharmaceutical Excipients: Potential use in drug delivery systems as a biodegradable polymer component or solubilizer (subject to appropriate grade and regulatory approval).
• Lubricant & Metalworking Fluids: Functions as a base fluid or additive component providing lubrication and stability.
• Adhesives and Sealants: Incorporated to adjust rheology, enhance flexibility, and improve bonding performance.

Quality Control

Our Poly(Oxy-1,2-Ethanediyl), α-Hydro-ω-Hydroxy-, Ether With 1,3-Benzenediol is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent composition, purity, and performance. Certificates of Analysis (COA) detailing key parameters such as average molecular weight, hydroxyl value, and moisture content are provided to guarantee compliance with your specifications and industry standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which may affect product quality.
