Strong, Durable and Heat Resistant
Manufactured by DuPont™, Kevlar is renowned for its exceptional strength, durability and heat resistance. With a tensile strength of 8.1 kilonewtons per tex (kN/tex), Kevlar is one of the strongest commercially available threads.
In addition, its melting point surpasses 800°F (427°C), making it incredibly heat resistant.
Product Benefits
Kevlar has a host of outstanding properties that set it apart from other materials and make it the go-to choice for various industries:
Unmatched Tensile Strength
Kevlar’s inter-chain bonds and tightly spun fibers make it incredibly strong and lightweight. It possesses a tensile strength 10 times greater than steel on an equal weight basis.
Exceptional Heat Resistance
With a melting point and decomposition temperature in excess of 427°C, this high-quality aramid fiber remains stable and retains its structural integrity even under extreme heat conditions.
Low Elongation and High Modulus
Kevlar has a low elongation of only 3.6%, making it ideal for applications that require minimal stretch, while its high modulus of 131 GPa provides stiffness and structural integrity.
Abrasion, Cut, Puncture and Impact Resistance
Highly resistant to abrasion, cuts, punctures and impacts, Kevlar offers unparalleled protection, making it ideal for a wide range of protective clothing and equipment.
Versatile Applications
Outstanding strength, durability and thermal stability make Kevlar a versatile material used in everything from fiber optics and rubber reinforcement to ropes and cables.
Choosing the Right Product
Goodfellow offers various forms of Kevlar:
Staple Fibers: These short, discrete fibers can be blended with other materials or processed into non-woven fabrics. They provide added strength and durability to composite materials.
Continuous Filament Yarns: Long, continuous strands of Kevlar fibers, commonly used in reinforcement applications such as ropes, cables, and fabrics.
Paper: A thin, flexible sheet made from Kevlar fibers that offers excellent strength, heat resistance, and electrical insulation properties. Used in gaskets, electrical insulation and filtration.
Spun Laced Fabrics: Non-woven fabrics made by interlocking Kevlar fibers using high-pressure water jets. They exhibit high strength, tear resistance, and flexibility, making them suitable for protective clothing and industrial applications.
