Para-aramids and para-aramid fibers: Kevlar® и Twaron®

Para-Aramid Fibers Kevlar® and Twaron®: Properties, Advantages, and Applications

What Are Para-Aramid Fibers?

Para-aramid fibers are high-performance synthetic materials known for their exceptional strength, heat resistance, and lightweight nature. The most recognized brands in this category are Kevlar® (by DuPont) and Twaron® (by Akzo/Acordis). These fibers are widely used in industry, construction, defense, aerospace, and personal protective equipment.

Kevlar® – The Leader Among Para-Aramids

Kevlar® is a registered trademark of DuPont, which first introduced the material in the early 1970s. Today, Kevlar® is also manufactured by the joint venture DuPont-Toray Co., Ltd in Japan.

Key Properties of Kevlar®:

• Extremely high tensile strength (up to 260 cN/tex)

• Low density (up to five times lighter than steel with comparable strength)

• High elasticity and impact resistance

• Excellent thermal resistance (withstands up to 370 °C, carbonization starts at 425 °C)

• Non-melting and non-flammable (Kevlar® 129 oxygen index = 30)

Kevlar® Series and Generations

Kevlar® para-aramid fibers are available in various series depending on specific properties:

• Kevlar® 29 – standard grade with good strength and heat resistance

• Kevlar® 49 – increased stiffness, ideal for composite reinforcement

• Kevlar® HM – offers 40% more elasticity compared to Kevlar® 29

• Kevlar® HT – 20% higher tensile strength, widely used in aerospace applications

Twaron® – A Worthy Alternative to Kevlar®

Twaron® is a widely-used para-aramid fiber developed by Akzo (later Acordis). It offers similar performance to Kevlar®, with its own unique production technologies. Twaron® is used in body armor, cable reinforcement, composites, and other high-strength applications.

Applications of Para-Aramid Fibers

• Bulletproof vests and protective clothing

• Automotive and aerospace components

• Fiber-optic cable reinforcements

• Construction-grade composite materials

• Brake pads, belts, and tires

• Aerospace and space technology

Operational Considerations

While para-aramid fibers are resistant to heat and mechanical stress, they are sensitive to ultraviolet radiation. For optimal durability, avoid prolonged exposure to direct sunlight or use UV-protective coatings.
