For procurement specialists and R&D professionals in the chemical industry, a thorough understanding of product specifications is vital for making informed purchasing decisions. Tetrabromophthalic Anhydride (TBPA), identified by CAS 632-79-1, is a compound with distinct properties that dictate its diverse applications. As a reputable manufacturer and supplier of TBPA from China, we provide a detailed overview of its key characteristics to assist you in evaluating its suitability for your needs.

The most commonly observed appearance of Tetrabromophthalic Anhydride is a white to light yellow powder. This physical state is consistent across high-purity grades suitable for demanding industrial uses. Its chemical composition, C8Br4O3, features a phthalic anhydride core substituted with four bromine atoms. This high bromine content, typically assaying at a minimum of 67%, is the source of its potent flame retardant capabilities.

A critical specification for TBPA is its melting point, which is notably high, generally reported as 270°C or above. This elevated melting point signifies good thermal stability, making it suitable for processes and applications that involve high temperatures without significant degradation. This characteristic is particularly advantageous when TBPA is used as a reactive flame retardant in polymers that are processed or used at elevated temperatures.

Other important specifications often include a maximum sulfate content of 0.3% and a maximum moisture content of 0.2%. These parameters are crucial for ensuring the purity and reactivity of the compound. When you buy Tetrabromophthalic Anhydride, understanding these specifications allows you to predict its performance accurately in your formulations. As a trusted supplier, we ensure that our product consistently meets these rigorous standards.

The detailed technical specifications, including bromine content and melting point, are essential for formulators and manufacturers who depend on predictable chemical behavior. We encourage you to inquire about our product's full specifications and request a sample. Partnering with a reliable manufacturer in China means you get access to high-quality Tetrabromophthalic Anhydride (CAS 632-79-1) at a competitive price, backed by a commitment to excellence.
