This unique product is recommended for electrical sockets, timers, and light fixtures, plus electrical conduit, both smooth and corrugated.
The proprietary flame additive in Cel-Span® 625 works by intumescences chemistry, which is initiated by heat. This chemical reaction forms a char barrier and thus excludes oxygen from the fuel and temperature sources. We recommend that the barrel zone temperatures be set at 360° - 380°F for optimum processing of electrical conduit both smooth and corrugated types.
