Kevlar® Physical Properties Guide

Kevlar® para-aramid fiber is known for its high tensile strength, low elongation, and excellent fatigue resistance, making it suitable for applications requiring durability under continuous load. The fiber maintains dimensional stability under stress and performs well across a wide temperature range.  Kevlar® does not melt and instead decomposes at elevated temperatures, contributing to its widespread use in heat-resistant and flame-protective applications.

Kevlar® Resistance Guide

Para-aramid fibers, such as Kevlar®, exhibit excellent resistance to high temperatures, maintaining their mechanical properties even at elevated temperatures. This heat resistance makes them suitable for applications in thermal insulation and protective clothing. Additionally, Kevlar® fibers demonstrate fair to good chemical resistance, enabling them to withstand short-term exposure to acids, alkalis, and many organic solvents without significant degradation. These fibers are not suggested for long term chemical exposure.

This fiber will degrade with prolonged UV light exposure. These fibers will brown and weaken over time.  Please keep this fiber stored away in a dark room and in the UV protective bag the fiber was shipped in.

This fiber will absorb atmospheric moisture up to 5-7% in weight. This fiber should be stored in a cool, dry room with low humidity. A desiccant bag was included with this fiber to prevent regain during transit and short-term storage at your facility.

Acid: Prolonged exposure to concentrated strong acids will cause degradation
Alkali: Degrades with prolonged exposure to Sodium Hypochlorite
Organic Solvent: Moderate degradation in Carbon Tetrachloride and Ethylene Glycol

Continuous Operating Temperature Range (°C): -40 to 200
Short Term Exposure (°C): 420
Degradation Temperature (°C): 480

Kevlar® Performance Highlights

  • High strength: Exceptional strength relative to weight, ideal for load-bearing and reinforcement applications.
  • Low Elongation: Maintains dimensional stability under sustained tension and cyclic loading.
  • Impact Resistance: Excellent energy absorption and resistance to sudden impact.
  • Abrasion Resistance: Withstands repeated wear in demanding mechanical environments.
  • Thermal Stability: Maintains mechanical integrity across a wide temperature range and does not melt.
  • Chemical Resistance: Resists many organic solvents and weak acids (see limitations).
  • Flame Resistance: Naturally flame resistant and self-extinguishing.
  • Electrical Insulation: Non-conductive with good dielectric properties.
  • Long Service Life: Proven durability in harsh industrial and aerospace environments.
