Definition and Area of Use :
Chlorinated paraffins are solid, high chlorine content (70%), long carbon chain length (C20-C30) chlorinated paraffins, except for sticky, colorless or yellowish, dense oils. Chlorinated paraffins do not have the characteristic faint and unpleasant odor. The odor is probably due to small amounts of the product from the relatively low molecular weight with a small but measurable vapor pressure. The carbon chain length and chlorine content of the paraffin determine the chemical and physical properties of chlorinated paraffins. Increases in the carbon chain length and degree of chlorination of certain paraffins increase viscosity and density, but decrease volatility.
Chlorinated paraffins normally contain stabilizers added to prevent decomposition. Common stabilizers include Epoxidized esters and Epoxidized compounds such as soybean oils, pentaerythritol, thymol, urea, glycidyl ethers, acetonitriles and organic phosphates.
