Innovative fire protection textiles for lithium-ion batteries

Rex’s fire curtains pass rigorous fire resistance tests and classifications according to industry standards.

By selecting the most suitable fiber materials, such as aramid, preox, glass, and silicate fibers, combined with special finishing treatments, the manufacturer of technical textiles, Rex Industrie-Produkte Graf von Rex GmbH, Vellberg/Germany, can develop its products according to the needs of end users. Rex is available as a development partner for high-tech heat- and flame-protection solutions and will be present at the Techtextil in Frankfurt/Germany.

The increasing prominence of electric vehicles and storage systems and the associated changes in the standard requirements for fire and protection classes resulting from e-mobility necessitate innovative fire protection measures for lithium-ion batteries. Rex’s protective textile engineered for fire-limiting blankets offers crucial benefits in containing fires, protecting surrounding areas, reducing water consumption during extinguishing, and preventing textile breakage even at temperatures exceeding 900°C.

Rex's highlight is its lightweight, flexible, and thin textile fabrics, customizable to manufacturers' needs for smoke barriers, fire barriers, and other fire protection systems, meeting a minimum protection target of EW60 and ensuring room closure with radiation penetration limitation for 60 minutes. The fabric, with its special coating and aluminum foil combination, offers fire resistance up to 900°C, >90% heat reflection, and <1mm thickness.
