Para aramid Tape

What is kevlar belt (para-aramid webbing, kevlar rope, para aramid tape, aramid string)?

• Flat para-aramid tape width: 2cm, 3cm, 5cm, 8cm, other specifications can be customized. usually 50~100 meters per roll .
• Round para-aramid tape width: 0.5cm, 0.8cm, 1cm, 1.2cm, other specifications can be customized.

1. Flame retardant and fireproof: it will not burn when exposed to fire, only carbonizes but does not melt. Flame retardant performance complies with EU EN479 fire protection standard.
2. Heat resistance: It can be used for a long time in the range of -196℃ to 220℃, and does not decompose or melt at high temperatures of 560 ℃.
3. Chemical resistance: resistant to corrosion by most highly concentrated inorganic acids and other chemicals, hydrolysis and steam corrosion.
4. High strength and high modulus: extremely high strength, 5 to 6 times that of high-quality steel, 2 to 3 times that of steel or glass fiber, toughness that is 2 times that of steel, and weight only 1/5 of steel. The strong toughness of aramid also makes it extremely difficult to cut and process, requiring special electric shears imported from Japan to cut it.
5. Wear resistance: excellent wear resistance, the wear resistance coefficient exceeds 100,000 times. Aging resistance, longer service life.
6. Good mechanical properties: elongation at break <3.5%, breaking strength 23-36 d/g.
7. Para-aramid is relatively sensitive to uv. When exposed to ultraviolet rays or artificial light sources for a long time, it will turn from yellow to brown over time, but it has no effect on the performance of the product and can be used outdoors for about 50 years. 

Characteristics of kevlar belt

1. Fire retardant only carbonized, no molten droplets, it will automatically extinguish within 2 seconds after leaving the open flame. It can be used for a long time below 260°C. Its flame retardant performance complies with the EU EN479 fire protection standard.
2. High strength, impact resistance the elongation is low, the elongation at break is <3.5%, and the breaking strength is 23-36 G/D.
3. Wear-resistant and cut-resistant, the wear-resistance coefficient exceeds 100,000 times, and the cutting resistance when mixed with glass fiber is level 5.
4. Acid and alkali resistance, corrosion resistance, organic solvent resistance.
5. The low flammability limiting oxygen index (LOI) is 29%, and carbonization and decomposition begins above 560°C. Excellent high temperature resistance, can work for a long time in acid and alkali environments from -200°C to 250°C. Tape strength still maintains 70% after 1000 hours at 290°C, para-aramid is sensitive to prolonged exposure to ultraviolet (UV).

What are the applications of kevlar belt?

Widely used in dry fire helmet head nets, fire breathing masks, etc. It has excellent bonding properties with high-temperature-resistant rubber such as silicone rubber. It is an ideal reinforced skeleton material for the current production of high-end automotive high-temperature-resistant booster pipes, oil-resistant pipes, hot water pipes and other pipes. The mesh cloth has consistent strength and elasticity in all directions. Good impact-resistant, suitable for making various special-shaped hoses.
