As our interconnected and increasingly sophisticated underground network grows, the need for conduit also grows. Conduit is installed on the walls and ceilings of underground tunnels to house cables that provide communications, signals, and power including emergency controls. Safety and reliability are paramount in this underground environment. Uninterrupted signals and power, emergency lighting when needed, and protection against the spread of fire are top priorities when designing reliable and safe underground systems.
To adapt MEGOLON halogen-free compounds for use in conduit applications, Alphagary’s material scientists created formulations that extrude easily into a 3-5mm thick wall. The balance of rigidity with plasticity along with MEGOLON’s proven halogen-free and fire retardancy characteristics provides conduit manufacturers with a flame-retardant option for applications requiring these attributes.
MEGOLON LSHF compounds as sheathing (jacket) material
Across the world, MEGOLON® low smoke, halogen-free compounds have earned recognition from global cable designers as a capable sheathing/jacket material for multiple cable designs. This is largely because of the halogen-free flame retardant properties of MEGOLON, and its contribution to essential fire performance standards in European (CPR), the United States (NEC) and other global testing protocol. In fact, MEGOLON compounds are a recognized component by Underwriters Laboratories for “acid gas, acidity and conductivity of combusted materials and assessment of halogens” in document AATJ2.
