SAA TPS Flat Cable: How AS/NZS 5000.2 Non-Migratory Sheath Protects Building Insulation
When standard PVC cable contacts polystyrene (EPS or XPS) insulation, the plasticizers that keep the sheath flexible migrate out of the cable and are absorbed by the foam. The cable hardens and cracks. The polystyrene swells and loses its insulating properties. Within years—not decades—the sheath can become brittle enough to expose conductors, creating shock and […]
