Description

Poly(Propylene Glycol) Bis(2-Aminopropyl Ether) is a versatile, amine-terminated polyether diol, widely recognized as a key building block in polymer synthesis. Its bifunctional nature, featuring primary amine end groups, makes it an essential component for creating high-performance, flexible polymers with tailored properties. This product is particularly valuable for manufacturers in the polyurethane, epoxy resin, and specialty coatings industries seeking to enhance product flexibility, adhesion, and chemical resistance.

Application

• Polymer Synthesis: A crucial chain extender and curing agent in the production of polyurethane elastomers, sealants, and adhesives, imparting flexibility and toughness.
• Epoxy Systems: Used as a reactive diluent and flexibilizer in epoxy resin formulations for coatings, composites, and encapsulants.
• Surfactants & Demulsifiers: Serves as an intermediate for manufacturing non-ionic surfactants and oilfield chemicals used in crude oil demulsification.
• Fuel & Lubricant Additives: Employed as a precursor for dispersants and detergents that improve the performance of engine oils and industrial lubricants.
• Textile & Leather Auxiliaries: Acts as a softener and finishing agent intermediate to enhance the handle and durability of textiles and leather goods.
• Pharmaceutical & Personal Care Intermediates: Used in the synthesis of specialized polymers for controlled drug delivery and cosmetic formulations.

Quality Control

Our Poly(Propylene Glycol) Bis(2-Aminopropyl Ether) is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure consistent purity, amine value, and molecular weight distribution. Certificates of Analysis (COA) documenting key parameters are available upon request to support your quality assurance and regulatory compliance needs.

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 product is hygroscopic (moisture-sensitive) and should be kept under a dry inert atmosphere (e.g., nitrogen) after opening to prevent moisture absorption and oxidation. Keep away from strong acids and oxidizing agents.
