●High Heat Resistance: Can withstand continuous use at ~200–250°C and short-term exposure up to 500°C without melting.

●Flame Retardant: Self-extinguishing and non-conductive, with a LOI (Limiting Oxygen Index) of ~28–30, meaning they resist burning in normal oxygen levels.

●High Tensile Strength: Aramid fibers (e.g., Kevlar, Twaron) have tensile strengths up to 3,000–3,620 MPa, surpassing steel on a weight-for-weight basis.

●Low Electrical Conductivity: Good insulator, used in electrical applications.

●Abrasion Resistance: Highly durable against wear, though some aramids (like Kevlar) can suffer from axial compression fatigue.
