WebChlorinated polyethylene (PE-C or CPE) is an inexpensive variation of polyethylene, where chlorine is substituted for some of the hydrogen atoms. CPE has a chlorine content from 34 to 44%. Due to its soft, rubbery texture, CPE is added to polyvinyl chloride to increase its impact and weather resistance. WebChlorinated 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 ...
