Description

Poly[Oxycarbonqloxy(2,6-Dibromo-1,4-Phenylene)-(1-Methylethylidene)(3,5-Dibromo-1,4-Phenylene)] is a high-performance brominated polycarbonate polymer, valued for its exceptional flame retardancy and thermal stability. This engineered material is critical for applications requiring stringent fire safety standards without compromising mechanical integrity. It is primarily sought by manufacturers in the electronics, construction, and transportation sectors for producing inherently flame-retardant components and coatings.

Application

• Flame-Retardant Additive for Engineering Plastics: Used as a reactive or additive flame retardant in polycarbonate, polyester, and polyamide blends for electronic housings and connectors.
• High-Temperature Electrical Components: Formulated into insulating parts, circuit board substrates, and connectors that must meet UL94 V-0 ratings.
• Automotive & Aerospace Interiors: Incorporated into composite materials for seat components, interior panels, and wire insulation to enhance fire safety.
• Construction Materials: Used in flame-retardant coatings, films, and sheets for public infrastructure and building safety applications.
• Specialty Protective Coatings: Serves as a base polymer for intumescent and protective coatings on metals and other substrates.

Quality Control

Our production of brominated polycarbonate adheres to stringent quality management protocols. Every batch is analyzed to ensure consistent bromine content, molecular weight distribution, thermal stability, and color. Comprehensive Certificates of Analysis (COA) documenting purity, residual solvents, and key performance indicators 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 a controlled room temperature (15-25°C). Keep away from heat sources and incompatible materials. The container must be kept tightly sealed to prevent moisture absorption and contamination.
