Description

Amin Terminiertes Homo-Polymer Des Butadiens Oder Amin Terminiertes Co-Polymer Butadien-Acrylonitril, Restmonomerengehalt <50 Ppm is a family of reactive liquid polymers featuring primary amine end groups, available as either amine-terminated polybutadiene (ATPB) or amine-terminated butadiene-acrylonitrile (ATBN) copolymers. These polymers are critical for enhancing the toughness, flexibility, and adhesion properties of epoxy, polyurethane, and other thermoset resin systems. They are essential raw materials for formulators and manufacturers in the adhesives, sealants, coatings, and advanced composite materials industries, where precise chemical functionality and low residual monomer content ensure consistent performance and processing safety.

Application

• Epoxy Toughening & Flexibilization: Primary use as a reactive modifier to reduce brittleness and improve impact resistance and crack propagation in epoxy resins for structural adhesives, potting compounds, and composite matrices.
• Polyurethane Elastomers & Coatings: Acts as a chain extender or curative, contributing to the formation of segmented polyurethanes with enhanced mechanical properties, chemical resistance, and low-temperature flexibility.
• Adhesive & Sealant Formulations: Improves peel strength, adhesion to difficult substrates (e.g., plastics, metals), and elasticity in high-performance construction, automotive, and aerospace sealants and adhesives.
• Rubber Modification & Compatibilization: Used to modify and compatibilize various rubber blends, improving the interfacial adhesion between different polymer phases.
• Fuel-Resistant Sealants & Gaskets: The ATBN copolymer variant is particularly valued in formulations requiring resistance to fuels, oils, and hydrocarbons.
• Foundry & Tooling Resins: Incorporated into epoxy systems for flexible molds and patterns, providing the necessary tear strength and dimensional stability.
• Aerospace & Defense Composites: Critical component in composite matrices where damage tolerance, fatigue resistance, and lightweight properties are paramount.
• Electrical Encapsulation: Used in potting and encapsulation compounds to protect sensitive electronic components from thermal cycling, vibration, and moisture.

Quality Control

Our amine-terminated polymers are produced under strict quality management systems to ensure batch-to-batch consistency and performance reliability. Key parameters such as amine value, residual monomer content (<50 ppm), viscosity, and acrylonitrile content (for ATBN) are rigorously tested. A comprehensive Certificate of Analysis (COA) is provided with each shipment, detailing specifications and actual test results. We support compliance with relevant industry standards for raw materials used in advanced manufacturing.

Storage

Preserve in a tightly closed container, protected from light. This product is hygroscopic (moisture-sensitive) and should be stored under a dry, inert atmosphere (e.g., nitrogen) to prevent oxidation and amine group degradation. Recommended storage temperature is between 15°C and 25°C in a cool, dry, well-ventilated area away from heat sources and incompatible materials. Keep containers tightly sealed when not in use to minimize exposure to atmospheric moisture and carbon dioxide.
