Description

1,1'-(1-Methylethylidene)Bis(2,6-Dibromo-4,1-Phenylene)Bis[(Oxycarbonyl)Oxy]Bis(2,3,4,5,6-Pentabromobenzene) is a highly brominated aromatic compound, specifically a complex brominated flame retardant. This product matters for its exceptional ability to impart fire resistance to a wide range of polymeric materials, enhancing safety and compliance in finished goods. It is primarily needed by manufacturers in the plastics, textiles, and electronics industries seeking high-performance, additive flame retardants for demanding applications. Our supply is backed by stringent quality control to ensure batch-to-batch consistency and performance reliability.

Application

• High-Temperature Engineering Plastics: As a key additive flame retardant in polymers like polycarbonate (PC), polybutylene terephthalate (PBT), and their blends, where thermal stability is critical.
• Thermoset Resins & Composites: Used in epoxy resins and unsaturated polyesters for printed circuit boards (PCBs), electrical laminates, and composite materials requiring UL94 V-0 ratings.
• Wire & Cable Insulation: Incorporated into polyethylene (PE), polypropylene (PP), and ethylene-vinyl acetate (EVA) compounds to meet fire safety standards for construction and automotive wiring.
• Synthetic Fibers & Textiles: Applied as a flame-retardant finish or additive for technical textiles, upholstery, and protective clothing.
• Electronic Housings & Components: Provides flame retardancy to casings for connectors, switches, and housings in consumer electronics and appliances.
• Adhesives & Sealants: Enhances the fire resistance of high-performance adhesives and sealants used in construction and automotive assembly.

Quality Control

Every batch of our 1,1'-(1-Methylethylidene)Bis(2,6-Dibromo-4,1-Phenylene)Bis[(Oxycarbonyl)Oxy]Bis(2,3,4,5,6-Pentabromobenzene) is produced and tested under a strict Quality Management System. We ensure compliance with relevant industry specifications for flame retardant additives. Our products undergo rigorous quality testing, including assay, impurity profiling, and thermal stability checks. Certificates of Analysis (COA) detailing purity, bromine content, and other critical parameters 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). Keep away from heat, sparks, and open flame. This material is moisture-sensitive (hygroscopic); ensure containers are sealed tightly after use to prevent absorption of atmospheric moisture.
