Description

Carbonic Dichloride, Polymer With 4,4-(1-Methylethylidene)Bis2,6-Dibromophenol And 4,4-(1-Methylethylidene)Bisphenol, 4-(1-Methyl-1-Phenylethyl)Phenyl Ester is a specialized brominated polycarbonate copolymer designed for advanced material applications. This engineered polymer offers a unique combination of flame retardancy and thermal stability due to its incorporation of brominated bisphenol A units. It is essential for manufacturers requiring high-performance engineering plastics that meet stringent fire safety regulations without compromising mechanical properties.

Application

• Flame-Retardant Engineering Plastics: As a key additive or co-monomer in the production of high-temperature resistant polycarbonates and blends for electronics, automotive, and aerospace components.
• Electronic Housings and Connectors: Used in the formulation of plastics for enclosures, connectors, and internal parts that must comply with UL94 V-0 and other international flame retardancy standards.
• Transportation Interior Materials: Incorporated into polymers for aircraft, train, and automotive interiors where low smoke density and flame spread are critical safety requirements.
• Wire and Cable Insulation: Enhances the fire resistance of insulation and jacketing materials for critical power and data cables.
• Specialty Films and Sheets: Used to create transparent or opaque films with inherent flame retardancy for protective barriers, displays, and glazing applications.
• High-Performance Composite Matrices: Serves as a resin matrix in composites for structural applications demanding both strength and fire safety.

Quality Control

Our production of this brominated polycarbonate adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Quality is verified through analytical techniques including GPC (Gel Permeation Chromatography) for molecular weight distribution, bromine content analysis, and thermal stability testing (TGA). A comprehensive Certificate of Analysis (COA) detailing purity, bromine content, thermal properties, and other critical parameters is provided with every shipment.

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 open flame. The product should be stored under dry conditions to prevent moisture absorption, which could affect processing characteristics.
