Chlorendic Anhydride, identified by its CAS number 115-27-5, is a prominent chemical compound utilized across various industrial sectors, primarily for its exceptional flame-retardant capabilities and its function as a reactive intermediate. Its unique chlorinated bicyclic structure confers specific chemical properties that make it indispensable in the production of high-performance polymers and resins. For professionals in procurement, R&D, and formulation, understanding the nuances of this chemical and reliable sourcing channels is paramount. As a dedicated manufacturer and supplier based in China, we aim to provide comprehensive information and consistent supply of this vital material.

The chemical properties of Chlorendic Anhydride are key to its widespread application. It typically presents as a white crystal powder with a high purity, often exceeding 99%. This purity is crucial for ensuring consistent reactivity and predictable outcomes in downstream applications. Its molecular formula is C9H2Cl6O3, with a molecular weight of 370.83 g/mol. The presence of six chlorine atoms within its structure is fundamental to its flame-retardant efficacy, allowing it to disrupt the combustion process.

The primary uses of Chlorendic Anhydride leverage its reactive nature and inherent fire resistance. It is widely employed as a reactive flame retardant in polymers such as unsaturated polyesters, polyurethanes, and epoxy resins. Unlike additive flame retardants, Chlorendic Anhydride chemically bonds with the polymer matrix, providing permanent fire resistance. This integration is vital for applications requiring long-term safety and performance. For businesses looking to buy materials that meet stringent fire safety regulations, Chlorendic Anhydride is a premier choice.

Furthermore, Chlorendic Anhydride serves as an effective epoxy curing agent. When used in epoxy formulations, it contributes to cured resins with excellent thermal stability and a high heat distortion temperature, often around 180°C. This characteristic makes it ideal for specialized applications in electronics, automotive components, and industrial coatings where resistance to heat and chemical exposure is critical. Scientists and formulators often rely on this compound for its ability to enhance the thermal performance of epoxy systems.

The global market for Chlorendic Anhydride is significantly supported by manufacturers in China, who offer competitive pricing and high-quality products. When considering procurement, it is essential to identify a reliable supplier that guarantees purity, consistent batch-to-batch quality, and sufficient production capacity. Engaging with a reputable manufacturer ensures a stable supply chain and access to competitive rates for bulk purchases. Requesting quotes and samples is a standard practice to verify quality and suitability for specific applications.

In conclusion, Chlorendic Anhydride (CAS 115-27-5) is a critical chemical intermediate with significant impact on flame retardancy and thermal performance in industrial applications. Its role as a reactive flame retardant and an epoxy curing agent underscores its importance. For companies seeking to source this compound, partnering with experienced Chinese manufacturers and suppliers provides access to high-quality material at competitive prices, facilitating the development of safer and more robust products.
