Taizhou Zhongsheng Fiberglass Launches Global-First“5-Level Thermal Management Matrix,” Redefining EV Fire Safety With DIN SPEC 91489 And EN 13501-1 Certification

Level 2: Tactical (Pre-Oxidized / Carbon Fiber): A "Lightweight Rapid Response" tool for racetracks and emergency teams. Using pre-oxidized fiber technology, it features "No-Melt, No-Drip" physical properties, maintaining fabric flexibility even after carbonization in a 1000°C fire to ensure rapid deployment.
Level 3: Professional (High Silica): The technical cornerstone of the matrix-the professional car fire blanket. Engineered for "Containment" of 1200°C thermal runaway, it uses >96% pure amorphous high silica fiber, an aerospace-grade material that ensures the blanket does not shrink or embrittle under extreme thermal shock.
Level 4 & 5: Advanced & Maximum (Graphite/Ceramic Coating): Designed for labs, military, and extreme environments. Using patented graphite-enhancement technology, it forms a microscopic expansion sealing layer in the fire, not only withstanding higher temperatures but also achieving efficient physical interception of toxic Hydrogen Fluoride (HF) gas.
The advantage of the Zhongsheng factory lies in its 150,000-square-meter closed-loop production system. From yarn drawing and weaving to specialized coating, every step is completed in-house, ensuring that every product in the "5-Level Matrix" accurately matches its designed temperature limit.
The Gold Standard: Differentiating Basic Protection from Professional Certification

CE, EN 1869:2019, and ASTM F1989
“The real challenge lies in jet fires and toxic gas leaks,” noted the Technical Director at Taizhou Zhongsheng.“Our professional series passed the EN 13501-1 fire classification and complies with the latest German DIN SPEC 91489 technical specification. This is currently the world's most stringent test for suppressing lithium-ion vehicle fires. It requires the material to maintain physical integrity when facing high-temperature fire jets from battery packs and effectively block thermal radiation from spreading to adjacent assets.”
