Product Description

Brief introduction:
What is kevlar twisted yarn?
Kevlar twisted yarn has extremely high tensile strength, exceeding 28 grams per denier, which is 5-6 times that of high-quality steel, with a modulus 2-3 times that of steel or fiberglass, toughness twice that of steel, and weight only 1/5 of steel. The strength and toughness of aramid 1414 also make it extremely difficult to cut and process, requiring expensive specialized tools.
Aramid 1414 has a wide range of continuous use temperatures, allowing for long-term normal operation within the range of -196 ºC to 330 ºC. The shrinkage rate at 150 ºC is 0, and it does not decompose or melt at high temperatures of 560 ºC. Its heat resistance is superior to that of aramid 1313, and it has good insulation and corrosion resistance, with a long life cycle, earning it the reputation of "synthetic steel wire".


Mechanical properties of Kevlar twisted yarn
The strength is 3.6Gpa, the elongation modulus is 131Gpa, and the elongation at break is 2.8% -3.5%. It has extremely high strength, with a weight to weight ratio of 5-6 times that of steel wire, a modulus of 2-3 times that of steel wire or fiberglass, and 7 times that of high-strength nylon. It is recognized as one of the world's sewing threads.

Thermal properties of Kevlar twisted yarn
Long term use temperature: 380 ºC
Axial thermal expansion coefficient: -2 × 10 ^ (-6)/K
Thermal conductivity: 0.048 W (m · K)
It has high stability in temperature performance, not only able to be used for a long time in the temperature range of -196 ºC to 380 ºC without significant changes or losses, but also has non solubility, non combustion (fire resistance), and will only start carbonization at 427 ºC. Even at a low temperature of -196 ºC, it will not become brittle or suffer performance losses. It can also withstand temperature resistance up to 585 ºC for short periods of contact.

The comprehensive outstanding performance of Kevlar twisted yarn
High tensile
High tensile strength function
Low elongation,
High modulus
High fracture strength

What is aramid kevlar rope?
Aramid kevlar rope is a composite high-performance rope woven from Kevlar fibers. It has extremely high strength (more than 28G/D), which is 5-6 times stronger than high-quality steel. The modulus is 2-3 times than that of steel or fiberglass, and the toughness is 2 times that of steel. And the weight is only 1/5 of the steel
The continuous use temperature range of aramid rope is extremely wide, and it can be used normally for a long time within the range of -196 ºC to 350 ºC. The shrinkage rate is 0 at a temperature of 150 ºC, and it does not decompose or melt at a high temperature of 560 ºC. And it has good insulation and corrosion resistance, with a long life cycle.
Due to the special performance of aramid ropes, they are now widely used in many fields that have special requirements for ropes, such as engineering cables, safety ropes, high-altitude operation ropes, traction ropes, aramid leisure ropes, glider ropes, transportation lifting ropes, roller conveyor ropes, fire retardant ropes, high-temperature resistant ropes, etc.

What is aramid kevalr tape?
Aramid woven tape is made of Dupont Kevlar K-29 fiber filament woven.
Long term use temperature: 380 ºC
Axial thermal expansion coefficient: -2 × 10 (-6)/K,
Thermal conductivity: 0.048 W (m · K)
It has high stability in temperature performance, not only able to be used for a long time within the temperature range of -196 ºC to 204 ºC without significant changes or losses, but also has non solubility, non combustion (fire resistance), and will only carbonize at 427 ºC, with excellent temperature resistance up to 538 ºC for short-term contact.
Application fields include various special clothing belts, waist belts, safety protection, aerospace, high-speed rail warships,  fire protection, mechanical transmission lifting, and so on.
