Pre-Oxidized Fiber Fire Retardant Felt: The Ultimate Heat-Resistant Solution
Introduction
In industries and applications where extreme heat, fire hazards, and thermal insulation are critical concerns, pre-oxidized fiber fireproof cotton** stands out as a superior material. Known for its exceptional heat resistance, durability, and flame-retardant properties, this specialized fabric is widely used in firefighting, industrial insulation, aerospace, and protective clothing.

This article explores the **features, benefits, and applications** of pre-oxidized fiber fireproof cotton, explaining why it is a preferred choice for high-temperature environments.
What Is Pre-Oxidized fire-retardant polyester fabric?

Pre-oxidized fiber Fireproof felt is a high-performance material made from **polyacrylonitrile (PAN) fibers** that undergo controlled oxidation at high temperatures (200–300°C). This process enhances the fibers’ thermal stability, making them resistant to flames, heat, and chemical degradation.
Unlike traditional cotton or synthetic fabrics, pre-oxidized fibers do not melt, drip, or support combustion, ensuring reliable protection in extreme conditions.
Key Features & Benefits
1. Exceptional Heat & Flame Resistance
- Withstands temperatures up to **500–600°C (932–1112°F)**.
- Does not ignite or contribute to flame spread (meets **UL94, EN45545, and other fire safety standards**).
2. Lightweight & Flexible**
- Unlike ceramic fiber or asbestos, pre-oxidized cotton remains soft and flexible, allowing for easy shaping and installation.
3. Chemical & Corrosion Resistance
- Resistant to acids, alkalis, and most industrial chemicals, ensuring long-term durability.
4. Low Thermal Conductivity
- Provides excellent **thermal insulation**, reducing heat transfer and protecting surfaces from extreme temperatures.
5. Environmentally Friendly
- Non-toxic, asbestos-free, and produces minimal smoke when exposed to fire.
Common Applications
Due to its superior properties, pre-oxidized fiber fireproof cotton is used in:
✅ **Firefighting & Rescue Gear** – Fire blankets, protective suits, and heat shields.
✅ **Industrial Insulation** – Pipe wrapping, furnace linings, and boiler insulation.
✅ **Aerospace & Automotive** – Heat shields for engines, exhaust systems, and battery compartments in EVs.
✅ **Electrical & Electronics** – Insulation for cables, transformers, and lithium-ion battery packs.
✅ **Construction & Home Safety** – Fireproof curtains, wall insulation, and emergency escape blankets.
