FR Kevlar aramid long-fiber fabric

Key Characteristics

Flame Resistance: The material is inherently flame-retardant (FR), self-extinguishing when removed from a flame, and does not melt or drip at high temperatures. It maintains stability up to 560°C (1040°F).

High Strength-to-Weight Ratio: Kevlar fiber has a tensile strength several times stronger than steel wire of the same weight, making it highly durable while remaining lightweight.

Impact and Abrasion Resistance: The fabric has excellent impact and abrasion resistance, which is why it's widely used in protective gear like cut-resistant gloves and bulletproof vests.

Chemical Resistance: It offers good resistance to many acids, alkalis, and organic solvents, though prolonged chemical exposure is not recommended.

Electrical Insulation: Kevlar fabric also has good electrical insulation properties.

UV Sensitivity: A key limitation is its poor resistance to ultraviolet (UV) light; prolonged exposure can cause degradation and discoloration, so it should be stored away from direct sunlight. 

Applications

Due to its unique combination of properties, Kevlar aramid filament fabric is used across numerous industries: 

Protective Clothing: Bulletproof vests, helmets, firefighting gear, and cut-resistant gloves.

Aerospace and Automotive: Aircraft fuselage panels, helicopter rotor blades, and tire reinforcement, valued for its strength and lightweight properties.

Composites: Used as a reinforcement fiber with resins (like epoxy) for high-impact applications such as kayaks, canoes, and sporting goods.

Industrial: Heat insulation, pipe wrapping, and reinforcement in various mechanical applications.
