Para aramid staple fiber

Para aramid fiber property

• Inherently Flame Retardant, High Temperature Resistance, High Strength, High Modulus, Tensile Strength
• Bulletproof, explosion-proof, electrical insulation, arc-proof
• High dimensional stability: extremely low creep,  light weight
• Electrical insulation, corrosion resistance, acid and alkali resistance
• Heat and fire resistance, excellent cut resistance
• negative coefficient of thermal expansion
• excellent thermal stability
  
  

  The difference between meta-aramid and para-aramid

  The temperature resistance of para-aramid fiber is higher than that of meta-aramid fiber. The continuous use temperature range is -196℃～204℃, and it will not decompose or melt at a high temperature of 560℃. The most notable characteristics of para-aramid fiber are high strength, high modulus, high temperature resistance, acid and alkali resistance, and light weight. It has good insulation and anti-aging performance, and has a long life cycle.  Aramid fiber cloth has excellent properties such as high strength, high modulus, high temperature and alkali resistance, light weight, insulation, anti-aging, long life cycle, stable chemical structure, no molten droplets when burned, and no toxic gas. Polyisophthalamide fiber is referred to as meta-aramid fiber, polyterephthalamide fiber is referred to as para-aramid fiber.

   What are the applications of para-aramid staple fiber

  1. Used for spinning, used in flame retardant, high temperature resistant and other industrial fields.

  2. Used for weaving after spinning, used in protective work clothes, such as: fire suits, racing suits, combat suits.

  3. Friction and sealing materials, reinforcement of composite materials, reinforcement of concrete structures in civil engineering, etc.

  4. Para-aramid is used to make needle-punched aramid felt, mainly for fireproof blanket, welding blanket, flame retardant felt, high temperature resistant felt , thermal barrier , fire blocking layer .

  5. Gloves made of para-aramid can prevent fingers from being cut, rubbed, punctured, high temperature and flames during industrial operations.

  6. Aramid staple fiber has ideal wear resistance and high temperature resistance, replacing asbestos. The addition of 5% para-aramid fiber can achieve the effect of 20% asbestos. It can reduce the braking noise of the brake pads, enhance the wear resistance, effectively shorten the braking distance, prolong the service life and reduce the replacement frequency.
