Description

1,2-Propanediol, Polymer With Methyloxirane And Oxirane is a polyether polyol copolymer derived from propylene glycol, propylene oxide, and ethylene oxide. This versatile polymer is valued for its tunable hydrophilic-lipophilic balance and surfactant properties, making it a critical intermediate in advanced material synthesis. It is primarily sought by manufacturers in the polyurethane, coatings, adhesives, and specialty chemical industries for creating tailored performance materials.

Application

• Polyurethane Systems: As a key polyol component for flexible and rigid foams, elastomers, and coatings, offering control over foam density, flexibility, and cell structure.
• Surfactants & Emulsifiers: Serves as a non-ionic surfactant or emulsifier base in industrial and institutional cleaning formulations, agrochemicals, and textile processing aids.
• Polymer Modification: Used as a reactive intermediate or compatibilizer to modify the properties of other polymers, improving flexibility, adhesion, or moisture resistance.
• Lubricants & Functional Fluids: Employed in the formulation of synthetic lubricants, hydraulic fluids, and metalworking fluids where controlled viscosity and stability are required.
• Pharmaceutical & Cosmetic Excipients: Acts as a solubilizer, carrier, or base for topical formulations and controlled-release drug delivery systems (subject to appropriate grade and certification).
• Adhesives & Sealants: Functions as a polyol raw material in moisture-curing and reactive hot-melt adhesives, contributing to final adhesive strength and flexibility.

Quality Control

Our production of 1,2-Propanediol, Polymer With Methyloxirane And Oxirane adheres to stringent quality management protocols. Each batch is characterized for critical parameters including hydroxyl value, molecular weight distribution, viscosity, and water content to ensure consistency and performance. Certificates of Analysis (COA) documenting these specifications are provided with every shipment. We support compliance with relevant frameworks such as REACH and can supply grades suitable for applications requiring specific regulatory oversight.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive). Store in a cool, dry, well-ventilated area at room temperature (15-25°C/59-77°F). Keep container tightly sealed when not in use to prevent moisture absorption and contamination. Store away from strong oxidizing agents.
