Description

Benzenesulfonamide, 4-amino-, polymer with (chloromethyl)oxirane, 4,4'-(1-methylethylidene)bis[2,6-dibromophenol] and 2,2'-[(1-methylethylidene) bis(4,1-phenyleneoxymethylene)]bis[oxirane] is a specialized brominated epoxy polymer designed for high-performance applications. This advanced material matters because it combines flame retardancy with the structural integrity and adhesion properties of an epoxy resin system. It is primarily needed by formulators and manufacturers in the electronics, aerospace, and advanced composite materials industries seeking to meet stringent fire safety standards without compromising mechanical performance.

Application

• As a reactive flame-retardant additive in epoxy resin systems for printed circuit boards (PCBs) and semiconductor encapsulation.
• Formulation of high-performance composite matrices for aerospace and automotive components requiring UL94 V-0 ratings.
• Manufacture of flame-retardant adhesives and coatings for construction and transportation materials.
• Production of specialty potting and casting compounds for electrical and electronic devices.
• Use in advanced laminates where a combination of thermal stability, flame resistance, and strong adhesion is critical.
• As a key component in halogenated (brominated) epoxy hardeners or modifiers for tailored material properties.

Quality Control

Our production of this brominated epoxy polymer adheres to strict quality management systems. Every batch undergoes rigorous analytical testing to ensure consistent performance as a flame-retardant component. Key parameters monitored include bromine content, epoxy equivalent weight (EEW), viscosity, and thermal stability. Certificates of Analysis (COA) detailing batch-specific results 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). Keep away from heat sources and incompatible materials. This product may be hygroscopic (moisture-sensitive); ensure containers are sealed after use to prevent moisture absorption which can affect performance.
