Pre-Oxidized Fiber/Polyimide Fleece Fabric – Technical Data Sheet

Ultra-High Temperature Flame-Resistant Fleece

Product Overview:

Our innovative single-sided fleece fabric combines pre-oxidized fibers with polyimide to create a revolutionary thermal protection solution. This advanced material delivers exceptional heat resistance while maintaining the softness and comfort of traditional fleece, making it ideal for extreme cold-weather applications requiring flame protection.

Key Features:

Unmatched Thermal Performance:

Withstands continuous exposure up to 300°C

Brief exposure resistance to 1600°C (pre-ox fiber component)

LOI >32 (ASTM D2863)

Superior Comfort Characteristics:

Single-sided fleece construction provides:

Enhanced thermal insulation (0.28 clo value)

Moisture-wicking properties

Reduced weight (280gsm) vs conventional FR fleece

Advanced Safety Properties:

Inherently flame-resistant (no chemical treatments required)

Non-melting, non-dripping behavior

Self-extinguishing within 2 seconds (ASTM D6413)
