Product Features
Kevlar Aramid Filament Twisted Yarn Excellent Mechanical Properties
- Tensile Strength: 3.6 GPa
- Modulus of Elongation: 131 GPa
- Break Elongation: 2.8%–3.5%
- Kevlar exhibits extremely high strength, with a weight-to-tensile ratio 5-6 times that of steel wire, and a modulus 2-3 times that of steel wire or glass fiber, and 7 times that of high-strength nylon. It is recognized as one of the world's strongest fibers.
Kevlar Aramid Filament Twisted Yarn Excellent Thermal Properties
- Long-Term Use Temperature: 380°C
- Axial Thermal Expansion Coefficient: -2 × 10⁻⁶/K
- Thermal Conductivity: 0.048 W/(m·K)
- Kevlar exhibits high stability in temperature performance, capable of being used in temperatures ranging from -196°C to 380°C without significant changes or degradation. It does not dissolve or support combustion (flame resistance), only carbonizing at 427°C. Even at extremely low temperatures like -196°C, it does not become brittle or lose performance. It can also endure brief exposure to temperatures up to 585°C, demonstrating excellent high-temperature resistance.
Kevlar Aramid Filament Twisted Yarn Comprehensive Outstanding Performance
- High tensile strength and pulling force
- Low elongation, high modulus, high breaking strength
- High temperature resistance, flame resistance, non-flammable, only carbonizes
- High chemical resistance and stability
- Low thermal expansion coefficient
- Low specific gravity
- Electrical insulation properties
