    18.04.2020· Chlorinated paraffins are obtained by the chlorination of hydrocarbons and consist of 30-70% chlorine. They have low volatility and act as a flame retardant due to the presence of chlorine. Chlorinated paraffins offer high chemical stability and moisture resistance but are thermally unstable, which limits their applications to processing temperatures within 175⁰C.
