This system is FM Global approved and meets ASTM E-1725 "Fire Tests of Fire-Resistive Barrier Systems for Electrical System Components," the newest industry standard, requiring the highest level of performance for trays with zero to full cable loading. The system also meets ASTM E-1529 and provides circuit integrity ratings. FyreWrap complies with API and ExxonMobil specifications on fireproofing for petroleum and petrochemical processing plants.Product ComponentsCore Material: FyreWrap Cable Insulation products incorporate Insulfrax® Thermal Insulation as its core material. Insulfrax is a high-temperature insulation made from calcia, magnesia, silica chemistry designed to enhance biosolubility. It provides excellent insulation in a noncombustible blanket form.Encapsulating Material: The core insulation is completely encapsulated in an aluminum foil, fiberglass-reinforced scrim covering. This scrim provides additional handling strength as well as protection from tearing and moisture absorption. For outdoor installations, additional weather protection should be considered.Typical System PropertiesFM Global Approved - Wrap for Grouped Electrical CablesAPI 2218 "Fireproofing Practices in Petroleum and Petrochemical Processing Plants" - compliesExxonMobil GP14-03-01 "Fireproofing" Specification - compliesFire Exposure - Hydrocarbon Fire per ASTM E-1529Circuit Integrity - per ASTM E-1529Temperature Integrity - per ASTM E-1725Cable Loading - Empty to Fully Loaded TraysFire Rating - 30, 45, 60 minutesASTM E-84 Surface Burning Characteristics: (1) Unfaced Core: Flame/Smoke Rating = Zero, (2) FyreWrap: Flame/Smoke Rating < 25-50Information Provided by Unifrax I LLC
