To reduce the quantity of toxic gas and smoke during combustion, AFC Cable Systems® offers a line of Low Smoke Zero Halogen (LSZH) Liquid Tight Flexible Metal Conduits(LFMC).
Halogens are commonly found in the polymers used for conduit and cable jackets due to their flame-retardant properties and cost-effectiveness, but flame-resistant polymers containing halogens such as polyvinyl chloride (PVC) and ethylene propylene (FEP) emit toxic gases and smoke when burned.
AFC Cable Systems® designed a line of LSZH liquid-tight LFMC utilizing a halogen-free thermoplastic polyurethane jacket, which provides the same flame-retardant features as other conduit and cable jackets, but limits smoke and corrosive gas emissions that can harm individuals and damage equipment.
To protect people from inhaling toxic fumes, halogen-free conduit is increasingly crucial in residential, commercial, and industrial applications, including rail, aircraft, construction, and offshore installations. When in contact with flames, LSZHLFMC products release smoke at a lower rate and density, creating a safer environment and more distinct exit path for workers and individuals during a fire.
AFC Cable Systems® offers two LSZH flexible metal conduits, Non-UL® Low Smoke Zero Halogen Cable – Type LSZH-VF and UL® Low Smoke Zero Halogen Conduits – Type LSZH, LFMC. Both LFMC products feature a hot-dipped zinc galvanized low-carbon steel core, black thermoplastic polyurethane jacket, and comply with the following standards:
