What Are Low-Smoke Halogen-Free Materials and Why Important?
Low-Smoke Halogen-Free (LSHF/LSZH) materials are specially engineered compounds designed to minimize the amount of smoke and toxic gases emitted when exposed to fire or high heat. These materials are free from halogens, which include chlorine, fluorine, bromine, and iodine, commonly found in traditional PVC or other polymer-based products. LSHF materials are often used in applications where safety, particularly in the event of a fire, is critical.
- A Low Smoke Halogen-Free (LSHF) Junction Box is a specialized electrical fitting designed to house and protect electrical connections in conduit systems.
- LSHF junction boxes are engineered to minimize the release of toxic halogen gases and smoke during a fire, offering enhanced safety compared to traditional junction boxes.
- Available in various configurations, including 1-way, 2-way, 3-way, 4-way, and right-angle options, shallow and deep types, these junction boxes allow for multiple conduit connections, enabling seamless integration into complex electrical systems.
- By combining superior fire resistance with reduced environmental impact, LSHF junction boxes are an ideal choice for electrical installations that require high safety standards, such as those in public buildings, tunnels, and other critical infrastructure.
