127133-59-9 Usage
General Description
C21-38 alkanes, chlorinated, also known as chlorinated paraffin, are complex mixtures of polychlorinated n-alkanes. They are produced by the chlorination of straight-chain paraffin fractions derived from petroleum. These chemicals are used as flame retardants in a variety of products, including plastics, rubber, adhesives, and textiles. They serve as an effective additive to resist fire, providing thermal stability and reducing the risk of ignition and flames. However, their use has raised concerns due to their potential environmental and health impacts, including persistence in the environment, bioaccumulation, and toxicity to aquatic organisms. As a result, their use is regulated in many countries to limit exposure and protect human health and the environment.
