Fils de filament Kevlar®

Fils à coudre en filament Kevlar® conçus pour les applications à haute résistance et haute température. Fabriqués aux États-Unis, ces fils sont conçus pour répondre aux caractéristiques de performance de la norme A-A-55220, offrant une résistance, une durabilité et une stabilité thermique constantes dans les environnements exigeants.

Les fils de filament Kevlar® offrent une résistance à la traction exceptionnelle, un faible allongement et une excellente résistance à la chaleur et à l'abrasion. Bien que les fils d'aramide filés restent une solution importante, les fils de filament Kevlar® sont requis lorsque des performances structurelles et une résistance plus élevées sont nécessaires. Idéals pour l'aérospatiale, les équipements de protection, la couture industrielle et les coutures de renforcement, ces fils sont conçus pour une fiabilité dans les applications critiques. Les fils sont traités avec une légère finition cirée pour assurer un traitement optimal.

Fournis sur des bobines standard de 8 ou 16 oz, avec des tailles et des constructions personnalisées disponibles sur demande. Un certificat d'analyse (COA) avec traçabilité complète du lot est disponible sur demande.

Kevlar® Physical Properties Guide

Para-Aramid fibers such as Kevlar®,  offer a multitude of properties that make them an excellent choice for various applications. Their exceptional strength-to-weight ratio and high break strength provides high tensile strength and modulus, making them ideal for applications requiring robust and durable materials. Para-aramid fibers are great solution for applications where the fiber will be under constant load, taking advantage of low elongation and creep properties.

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 good chemical resistance, enabling them to withstand exposure to acids, alkalis, and many organic solvents without significant degradation. 

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 170
Short Term Exposure (°C): 420
Degradation Temperature (°C): 480
