2015-9-21 · The current use of chlorinated paraffins (SCCP, MCCP, and LCCP) in the United States is on the order of 150 million pounds per year. Production of short-chain and medium-chained chlorinated paraffins (C9 to C17) was 100 million pounds in 2007. A very small fraction of that number is attributable to import/export business. According to the Chlorinated Paraffins Industry Association, MCCPs represent the largest production and use of chlorinated paraffins in North America while SCCPs is only half that volume (CPIA, 2009). Marketing and use of SCCP has been restricted in the European Union (ECHA 2008a). In Canada, SCCPs are not currently manufactured and use was approximately 3000 metric tons in 2000 and 2001, the latest figures reported (Environment Canada, 2008). In the United States, Dover Chemical Corp. is the sole manufacturer of chlorinated paraffins …

SCCPs stand for short-chained chlorinated paraffins which is a mixture of different chlorinated chemicals with chain lengths between 10 and 13 carbons. They are produced by chlorination of n-alkanes.
