Description

Aziridine, Homopolymer, Propoxylated is a specialized polymeric amine derived from the ring-opening polymerization of aziridine (ethyleneimine) followed by propoxylation. This modification imparts unique properties, making it a versatile reactive intermediate and functional additive in advanced material synthesis. It is particularly valuable for industries requiring polymers with cationic functionality, cross-linking capability, or sites for further chemical modification.

Application

• As a cationic flocculant and retention aid in papermaking and water treatment processes.
• As a cross-linking agent and hardener for epoxy resins, polyurethanes, and other thermosetting polymers.
• As a precursor for functional polymers used in coatings, adhesives, and sealants to enhance adhesion and chemical resistance.
• In the synthesis of ion-exchange resins and chelating agents for metal recovery and purification.
• As a surface modifier and sizing agent for textiles and fibers to improve dye affinity and durability.
• In the formulation of personal care products as a conditioning and film-forming agent.

Quality Control

Our Aziridine, Homopolymer, Propoxylated is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure consistent performance, including determination of amine value, molecular weight distribution, and propoxylation degree. Certificates of Analysis (COA) documenting purity and key specifications are available upon request to support your quality assurance protocols.

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 to prevent moisture absorption and potential degradation. Keep away from strong acids and oxidizing agents.
