When you hear the term “chlorinated paraffins,” images of a scientific experiment in a lab may come to mind. However, chlorinated paraffins are used in a wide range of products that we use every day. These paraffins are chemical compounds that consist of n-alkanes with varying degrees of chlorination. They act as flame retardants, plasticizers, and lubricants in a variety of applications.
Chlorinated paraffins are found in many everyday products, including electronics, cables, PVC pipes, paints, and coatings. They are often used as a flame retardant because they can lower the temperature at which a material will ignite. They can also increase the efficiency of plasticizers by working with other chemicals to help blend the components of a product. In lubricants, chlorinated paraffins can help improve the performance and viscosity of the oil. All of these properties make them highly versatile and important in many industries.
Types of Chlorinated Paraffins
Chlorinated paraffins (CPs) are a group of complex, highly viscous, flame-retardant chemicals that are widely used in various industrial applications. CPs are classified according to their chlorination degree, carbon chain length, and the position of the chlorination on the carbon chains. There are several types of chlorinated paraffins categorized by these factors.
- Short-chain Chlorinated Paraffins (SCCPs): SCCPs have carbon chain lengths ranging from C10-C13 and are commonly used as flame retardants and plasticizers in the manufacturing of PVC cables and rubber products. SCCPs have been found to be toxic to aquatic and terrestrial organisms and are classified as persistent organic pollutants (POPs) under the Stockholm Convention.
- Medium-chain Chlorinated Paraffins (MCCPs): MCCPs have carbon chain lengths ranging from C14-C17 and are used in leather and fat liquors, metalworking fluids, and other industrial applications. MCCPs have also been detected in environmental samples and are considered to be persistent and bioaccumulative.
- Long-chain Chlorinated Paraffins (LCCPs): LCCPs have carbon chain lengths ranging from C18-C30 and are mainly used as flame retardants and softeners in rubber, paints, and coatings. LCCPs have a lower toxicity than SCCPs and MCCPs and are less persistent in the environment.
Chlorinated paraffins are also classified based on their chlorine content. CPs with chlorine content less than 50% are considered to be low-chlorine-content CPs, whereas those with a chlorine content greater than 50% are high-chlorine-content CPs. High-chlorine-content CPs are further divided into two subcategories: mid-chain and long-chain length chlorinated paraffins.
Overall, the types of chlorinated paraffins used depend on the specific application and industry. While their use is widespread, regulations have been implemented to monitor and control their production, use, and release into the environment due to their potential impact on human health and the environment.
