Description

Disodium Tetrabromophthalate is a high-purity, brominated organic salt widely utilized as a key intermediate and flame retardant synergist. Its primary commercial value lies in its ability to impart excellent fire resistance to polymers and plastics, particularly when used in combination with other halogenated compounds. This product is essential for manufacturers in the polymer, electronics, and construction material industries seeking to enhance the safety and regulatory compliance of their products.

Application

• As a reactive intermediate in the synthesis of advanced brominated flame retardants.
• As a flame retardant synergist in engineering thermoplastics such as polyamides (nylon), polyesters (PBT, PET), and epoxy resins.
• In the formulation of fire-resistant coatings and paints for electronic enclosures and construction materials.
• For the production of flame-retardant polyurethane foams used in furniture and insulation.
• In the wire and cable industry to improve the fire safety of polymer jacketing.
• As a component in specialty chemical formulations requiring high thermal stability and bromine content.

Quality Control

Our Disodium Tetrabromophthalate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent purity, correct chemical identity, and compliance with agreed specifications. A comprehensive Certificate of Analysis (COA) detailing assay, impurity profile, and physical parameters is provided with every shipment to guarantee traceability and quality assurance for our industrial partners.

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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent moisture absorption, which can affect product performance.
