It is a class of synthetic organic chemicals that are used in a wide range of industries, from window frames to pipes, flooring, and even shower curtains. The main use of chlorinated paraffin is as a plasticizer for the thermoplastic polymer PVC (polyvinyl chloride). Since pure PVC is rigid and brittle in nature, this limits its use in many applications. So this is where plasticizers such as chlorinated paraffin come in.
Not only does it give the plastic flexibility and softness, it also helps to improve PVC's resistance to heat, chemicals, and UV radiation, making it more durable in harsh environments. Its cost is much lower compared to other types of plasticizers such as phthalates. This makes it an attractive option for manufacturers who need to keep production costs low while still providing a high-quality product.
Despite its widespread use in the PVC industry, there have been some concerns about its safety in the past. However, rigorous testing has shown that it can be safely used in PVC products when used within the legal scope. For example, the European Chemicals Agency (ECHA) concluded that there was no need to take any further regulatory action on chlorinated paraffins because it does not pose a risk to human health or the environment.
It also has several environmental benefits. For example, it is non-flammable and has low volatility, which means it does not release harmful fumes or vapors into the environment. In addition, it is biodegradable, which means it will naturally break down over time and will not harm the environment.
