For chemical formulators and product developers, understanding the unique properties and application potential of specialized intermediates is crucial for innovation. Chlorendic Anhydride (CAS 115-27-5) is one such compound, offering a potent combination of flame retardancy, thermal stability, and resistance to chemical and physical degradation, making it a valuable asset in various industrial sectors.

Chlorendic Anhydride is characterized by its appearance as white, dust-free tiny crystals and its high purity, typically assaying at 99% minimum. Its molecular formula, C9H2Cl6O3, highlights a significant chlorine content (around 57%), which is the primary source of its exceptional flame-retardant capabilities. As a reactive acid anhydride, it chemically integrates into polymer matrices, providing permanent flame resistance that does not leach out over time. This is a significant advantage over additive flame retardants, especially in applications demanding long-term safety and performance.

The versatility of Chlorendic Anhydride stems from its ability to enhance a wide array of polymer systems. In epoxy resins, it functions as a highly effective cross-linking agent. This application is vital for creating materials used in laminates for electrical applications, potting and encapsulation, as well as adhesives that require superior flame resistance and high heat distortion temperatures. For formulators looking to buy epoxy resin components that offer robust protection, Chlorendic Anhydride is a prime candidate.

Unsaturated polyesters and alkyd resins also benefit significantly from the inclusion of Chlorendic Anhydride. It is used to produce flame-retardant, glass-reinforced polyester composites essential for construction panels, electrical equipment housings, and marine vessels. In the realm of coatings, alkyd-based formulations incorporating Chlorendic Anhydride are utilized extensively in industrial and marine environments due to their excellent chemical resistance and flame-retardant properties. For businesses aiming to purchase these advanced materials, understanding the role of a reliable supplier is paramount.

Furthermore, Chlorendic Anhydride finds utility in UV curable inks and coatings, where it improves adhesion to metals and enhances the overall durability and curing speed. Its contribution to fast curing and hardness makes it an attractive additive for modern printing and surface finishing applications. As a key supplier of this critical intermediate, NINGBO INNO PHARMCHEM CO.,LTD. is dedicated to meeting the needs of formulators worldwide. We encourage all interested parties to inquire about pricing, availability, and to request samples to explore the transformative potential of Chlorendic Anhydride in their next product development cycle.
