Description

Diallyl Tetrabromophthalate CAS NO 49693-09-6 is a halogenated phthalate ester derivative, specifically engineered as a high-performance reactive flame retardant and plasticizer. Its molecular structure provides excellent thermal stability and flame-retardant efficiency, making it a critical additive in polymer formulations where fire safety is paramount. This compound is essential for manufacturers in the electronics, construction, and wire & cable industries seeking to enhance the fire resistance of their plastic and resin products without compromising key material properties.

Application

• Primary use as a reactive flame retardant and plasticizer in unsaturated polyester resins (UPR) for fiberglass-reinforced plastics.
• Key additive in epoxy resin systems for printed circuit boards (PCBs) and electronic encapsulants to meet UL 94 V-0 standards.
• Flame-retardant component for PVC (polyvinyl chloride) and other vinyl-based compounds used in wire and cable insulation.
• Enhancement of fire resistance in thermoset plastics for construction materials, automotive parts, and transportation interiors.
• Used in the formulation of fire-retardant coatings and adhesives for industrial applications.
• Potential intermediate in the synthesis of more complex, high-molecular-weight flame-retardant additives.
