Aramid coated rope, made of para-aramid or aramid 1414, offers high strength, cut/abrasion resistance, flame retardancy, and thermal insulation. Ideal for firefighting, electrical work, marine towing, and helicopter lifting due to its durability and safety in extreme conditions.
Product Introduction
Aramid coated rope is a high-performance functional rope known for its high tensile strength, low elongation, abrasion resistance, cut resistance, insulation, flame retardancy, and high-temperature resistance. Its chemical names are para-aramid rope or aramid 1414 rope. Due to its exceptional properties, it is widely used in specialized applications such as firefighting protection, electrical work protection, deep-sea exploration towing, helicopter lifting, and other specialized operational protections.

Product Advantages
| Excellent thermal properties | |
| Decomposition temperature | Kevlar will not melt; at a heating rate of 10°C/minute, its decomposition temperature in air is 427°C-482°C, while under nitrogen it decomposes at approximately 538°C. The decomposition temperature varies with different heating rates and exposure times. |
| Effect of high temperature on expansion and contraction | Increasing temperature will reduce the modulus, tensile strength and elongation at break of Kevlar rope. This factor should be taken into account when using it for a long time at temperatures of 149℃-177℃ or higher. |
| Effect of high temperature on dimensional stability | When exposed to heat or hot water, Kevlar does not shrink like other organic fibers. Most other fibers shrink irreversibly. Kevlar’s coefficient of thermal expansion in the axial direction is very small and negative. |
| Effects of cryogenic (ultra-cold) conditions | The strength and elongation properties of Kevlar rope will not be negatively affected when exposed to -46°C, nor will it become brittle or degrade at temperatures of -196°C. |
| Excellent mechanical properties | |
| Kevlar rope is a new type of composite rope with super high strength (>25g/D), which is 6 times that of high-quality steel of the same density, 4 times that of nylon, 3 times that of high-quality steel and E-glass fiber, 2 times that of steel in toughness, and only 1/5 of the weight of steel. | |
| Flammability | |
| Kevlar is inherently flame-retardant but can ignite (oxygen index 29). It typically ceases burning after the fire source is removed, but can continue to smolder if ignited by pulp or fly ash. Experiments have shown that Kevlar does not continue to burn after 12 seconds of contact with a fire source and then removed. Increasing fabric thickness increases the afterglow time, but does not increase the burn length. It also produces no “drips” that could propagate the flame, a common problem with other organic fibers. | |
| The effects of ultraviolet rays | |
| Like other polymer materials, Kevlar is sensitive to UV light. Unprotected, it will fade from yellow to brown after prolonged exposure. Long-term exposure to UV light can cause a loss of organic properties, depending on the wavelength, exposure time, and radiation intensity. Fading of new fiber under indoor light is normal and does not affect its organic properties.
Kevlar’s natural color provides a self-shielding effect, with the outer fiber layer forming a protective barrier that shields the inner fibers of the fiber or fabric. Protecting Kevlar from UV light can be effectively achieved through an outer covering or coating. |
