Aramid Fiber Knowledge Popularization

At present, aramid products mainly include poly-m-phenylene isophthalamide fiber, poly-p-phenylene terephthalamide fiber and heterocyclic aromatic polyamide fiber.

  Meta-aramid has excellent heat resistance (decomposition temperature >400°C), flame resistance (limiting oxygen index >29%), good textile processability and insulation performance, and is widely used in aerospace, national defense, transportation, electronics, Important basic materials in the fields of environmental protection and personal protection.

  The representative of para-aramid is Kevlar produced by DuPont of the United States. Its main advantages are high strength, high modulus, high temperature resistance, and acid and alkali resistance.

  Meta-aramid is mostly used for fireproof materials, and para-aramid is mostly used for preventing mechanical damage such as body armor and cut-resistant gloves.
