Description

Bis(Pentabromobenzyl) Tetrabromophthalate CAS NO 82001-21-6 is a highly brominated aromatic ester compound engineered for superior flame retardancy. This high-performance additive is critical for enhancing fire safety in polymer systems where thermal stability and low volatility are paramount. It is primarily needed by manufacturers in the plastics, electronics, and construction industries seeking to meet stringent fire safety regulations without compromising material integrity.

Application

• As a highly effective flame retardant for engineering thermoplastics such as polyamides (PA), polybutylene terephthalate (PBT), and polycarbonate (PC) blends.
• In the formulation of fire-resistant coatings and adhesives for construction materials and industrial applications.
• For enhancing the fire safety of wire and cable insulation and jacketing compounds.
• In the production of flame-retardant composites and textiles requiring high thermal stability.
• As a key additive in electronic encapsulants and components to prevent fire propagation.
• For use in polymer systems where halogenated flame retardants with low blooming and migration are required.
