Description

Polyoxypropyleneamine CAS NO 26403-64-5 is a versatile amine-terminated polyether, widely recognized as a key building block in polymer synthesis. Its primary value lies in its dual functionality, acting as both a reactive amine and a flexible polyether chain, which is essential for creating tailored materials with specific properties. This chemical is critically needed by manufacturers in the polyurethane, epoxy curing agent, and surfactant industries, where it is used to enhance flexibility, adhesion, and surface activity in final products.

Application

• As a chain extender and curing agent in the production of flexible polyurethane elastomers, foams, and coatings.
• As a reactive intermediate for synthesizing epoxy resin curing agents with improved toughness and chemical resistance.
• In the formulation of surfactants and demulsifiers for the oilfield and agrochemical industries.
• As a key component in the manufacture of polyurea coatings and sealants, offering fast cure times and durability.
• For the synthesis of quaternary ammonium compounds used as biocides and fabric softeners.
• In adhesives and sealants to modify rheology and improve substrate wetting and adhesion.
• As a feedstock for producing specialty polyetheramines with specific molecular weights for advanced material applications.

Quality Control

Our Polyoxypropyleneamine is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistency and meets precise specifications for amine value, moisture content, and color. Certificates of Analysis (COA) documenting purity and key physical-chemical parameters are available for every shipment upon request, providing full traceability and quality assurance for your production processes.

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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after initial use to prevent absorption of atmospheric moisture, which can affect product performance.
