Para-Aramid Kernmantle Braided Rope – High-Temperature Fire Wick & Industrial Protection
Engineered for extreme heat resistance and superior liquid absorption, our Para-Aramid (Kevlar-type) Kernmantle Braided Ropes feature a dense braided outer sheath and a high-density multi-strand filament core (available in 8mm and customizable diameters from 2mm to 20mm+). Specially designed for fire juggling equipment, high-temperature seals, and industrial fuel-wicking applications. Exceptional tensile strength, non-melting up to 500°C (932°F), and long-lasting durability under repeated burning. Custom spool lengths, diameters, and denier specifications available.
Description
Our Para-Aramid Kernmantle Braided Rope is a premium-grade, heavy-duty technical cordage engineered for demanding high-temperature environments, fuel wicking, and specialized performance gear. Designed with a dual-layer Kernmantle structure, this rope combines maximum thermal stability with superior longitudinal tensile strength.
While our 8mm diameter is a popular standard for fire performance props and thermal seals, we fully support custom diameters, weights, and yarn constructions to meet your exact engineering specifications.
Key Features & Product Highlights
100% Para-Aramid Construction: Manufactured from high-tenacity Para-Aramid continuous filament yarn (Kevlar equivalent), offering high cut resistance, exceptional strength-to-weight ratio, and low elongation.
Fully Customizable Dimensions: Available in standard diameters (e.g., 4mm, 6mm, 8mm, 10mm, 12mm) and custom sizes tailored to your specific application.
Kernmantle Dual-Structure Engineering:
Outer Sheath (Mantle): Dense multi-warp circular braided jacket that resists abrasion, protects internal fibers, and prevents fraying under direct flame exposure.
Parallel Core (Kern): High-density multi-filament inner strands providing optimal capillary wicking action and structural integrity.
Superior Heat & Flame Resistance: Non-melting and non-dripping with a thermal decomposition threshold around 450°C (842°F).
High Fuel Retention (Capillary Wicking): The low-twist inner core creates micro-channels that efficiently absorb and transfer liquid fuels (kerosene, paraffin, white gas) for sustained, controllable burn times.
Chemical & Abrasion Resistance: Highly resistant to organic solvents, fuels, oils, and mechanical wear.

Primary Applications
Fire Shows & Juggling Props (Fire Wicks): Ideal for manufacturing and rewicking fire poi, torches, fire staffs, rope darts, and fire hoops. The core holds maximum fuel while the braided sheath withstands hundreds of burn cycles.
High-Temperature Industrial Seals: Used as thermal insulation packing for industrial furnaces, boilers, kilns, and high-temp pipe wraps.
Mechanical Fuel & Oil Wicking: Serves as an oil-conductive wick for industrial machinery, pumps, and valves operating under high-heat environments.
Safety & Protective Cordage: Suitable for winch lines, heat-shielding ties, and protective sleeving where standard nylon or polyester ropes would melt.
