- MICC cable: Uses a copper sheath and magnesium oxide insulation, which are non-combustible and can withstand extreme heat. Copper melts at 1,085°C, and magnesium oxide at 2,852°C. MICC cables release no toxic fumes during a fire and are made from recyclable materials.
- Soft skin / fire resistant cables: Are often made with plastic or polymer insulation, these cables can degrade under extreme heat, releasing toxic fumes. These materials are also difficult to recycle.
