FFKuS-EM-F-LS0H Low Smoke is a medium-sized corrugated plastic pipe made of special plastic, with a highly slippery inner layer, plastic jacket, in black (RAL 9005), non-flame-spreading, halogen-free. This corrugated plastic pipe is used especially for installation in concrete. The advantage is the extremely low smoke development. This makes escape routes easier to identify and, because it is halogen-free, no dangerous toxic and corrosive gases are produced. Halogen-free plastic corrugated pipes are marked with a continuous white longitudinal stripe.0605 DIN EN 61386-22 100% halogen-free according to DINV 0604-2-100 Smoke gas density according to DIN EN 61034-2 Minimum compressive strength: 750N/5cm
