Carbon Felt with Aluminum Film
Detailed

Product Description

FR Carbon Felt is a high-performance flame-retardant insulation material designed for demanding transportation and infrastructure applications. Manufactured from carbon-based fibers with inherent flame resistance, this felt provides excellent thermal insulation, fire protection, and long-term durability. It is especially suitable for metro and railway roof insulation systems, where strict fire safety and heat resistance standards are required.


 Features

Excellent Flame Retardancy

Inherently flame-resistant carbon fiber structure, self-extinguishing, low flame spread, and no melting or dripping under fire exposure.

Superior Thermal Insulation

Low thermal conductivity effectively reduces heat transfer, helping maintain stable internal temperatures in metro vehicles and underground stations.

High Temperature Resistance

Maintains structural stability under continuous high-temperature environments, suitable for roof and ceiling insulation near heat sources.

Lightweight & Durable

Low density with high mechanical strength, resistant to aging, deformation, and vibration during long-term operation.

Environmentally Stable

No toxic gas release under high temperatures, meeting modern transportation safety and environmental requirements.


Composition

FR Carbon Felt is produced from carbon fibers or oxidized polyacrylonitrile (OPAN) fibers, processed through needle-punched technology to form a uniform, flexible felt structure. The material achieves permanent flame retardancy without additional chemical coatings, ensuring stable performance throughout its service life.


Applications

  • Metro & Subway Roof Insulation

  • Railway Car Roof and Ceiling Thermal Insulation

  • Urban Rail Transit Vehicles

  • High-Temperature Fire-Safe Insulation Layers

  • Infrastructure Projects Requiring Fire-Resistant Materials
