Kevlar® Braid
Braided from 100% Kevlar® fiber, Rocket-Fibers Kevlar® Braid delivers exceptional tensile strength, flexibility, and resistance to fatigue. This continuous braided line is engineered for demanding applications across industrial, automotive, and sporting markets. Select braids are also available with specialized coatings to enhance performance properties such as abrasion resistance, UV stability, and adhesion.
Kevlar® Braid is offered in a range of breaking strengths, diameters, and lengths. Custom lengths are available upon request. Bulk quantities are offered for commercial use, with additional processing options — custom coating and winding—available as needed. Each product is conveniently wound on a plastic reel for easy handling and processing, and batch-specific certifications are included with every order to verify authenticity and performance.

Kevlar® Braid Product Details
- 100% Kevlar® fiber braided construction for maximum strength-to-weight performance.
- Continuous braided line with no splices — one continuous length per reel.
- Abrasion-resistant coating on select products for improved durability.
- Available in multiple break strengths and diameters to suit diverse applications.
- Excellent heat & flame resistance
- Custom lengths and bulk quantities available on request.
Product Performance
- Excellent strength-to-weight ratio makes this braid ideal for applications demanding high load capacity without added weight.
- Good abrasion resistance, especially on coated versions, extends service life in rugged conditions.
- Heat and flame resistance typical of para-aramid fibers like Kevlar®.
- Low stretch and creep under load, maintaining dimensional stability over time.
Kevlar® Braid Suggested Applications
-
Strength members in composite assemblies and hybrid cables
-
Pull cords, actuation lines, and control cables
-
Timing, guide, and reinforcement cords in belts, conveyors, and drive systems
-
Tethers, lanyards, and retention lines for industrial and aerospace use
-
Metal wire replacement where weight reduction and corrosion resistance are critical
-
High-temperature and flame-resistant cordage
-
Sporting, fishing, and bowfishing lines requiring cut resistance and minimal stretch
-
General industrial cordage for abrasion- and fatigue-resistant service
PARA-ARAMID 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, para-aramid 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
