Pre-oxidized silk fiber: An industrial safety "firewall"
Jun 23,2025
What are the characteristics of pre-oxidized fiber?
✅ Fire retardant performance: Limiting oxygen index >45%, non-melting and dripping when encountering fire, smokeless and non-toxic, reducing secondary disasters;
✅ Temperature resistance and heat insulation: It can work stably at high temperatures of 200℃-300℃ for a long time, and withstands instantaneous temperatures of 1000℃;
✅ Lightweight, tough and durable: Density is only 1.4g/cm³, tear-resistant, easy to fold, easy to cut, suitable for complex working conditions;
✅ Corrosion and acid-alkali resistance: Stable performance under strong chemical environments, extending service life;
✅ High-efficiency heat insulation: The porous structure locks in heat, and the thermal conductivity is as low as 0.02W/m·K, saving energy and reducing consumption.
Application scenarios:
🚒 Fire protection: Fire suits, escape blankets, welding blankets;
🚗 Automotive industry: Engine compartment sound insulation, battery thermal insulation layer, effectively delaying the spread of thermal runaway, contributing to the safety upgrade of new energy vehicles;
🏗️ Building insulation: Fireproof interlayer for curtain walls, pipe insulation, protecting building safety and energy saving;
🏭 Industrial sealing: Customized acid and alkali resistant felt, used for chemical pipeline sealing, service life increased by 3 times;
✈️ Aerospace cooperation: Development of ultra-lightweight pre-oxidized fiber aerogel composite felt to contribute to the lightweight design of spacecraft thermal insulation systems.
