Description

Bis(Pentabromophenyl) Carbonate is a high-performance brominated aromatic compound, primarily valued for its exceptional flame-retardant properties. This compound is a critical additive in polymer formulations where stringent fire safety standards must be met without compromising material integrity. It is essential for manufacturers in the electronics, construction, and transportation industries seeking to enhance the fire resistance of engineering plastics, coatings, and adhesives.

Application

• As a highly effective flame retardant in high-impact polystyrene (HIPS), polypropylene (PP), and polyethylene (PE).
• Key additive in fire-resistant coatings and paints for structural steel, cables, and textiles.
• Enhancing the fire safety of engineering thermoplastics used in electrical connectors, housings, and automotive components.
• Formulation of flame-retardant masterbatches and compounds for injection molding and extrusion processes.
• Used in the production of printed circuit boards (PCBs) and other electronic encapsulants.
• Improving fire resistance in thermoset resins, including epoxies and unsaturated polyesters.
• Application in specialty adhesives and sealants requiring UL94 V-0 ratings.
