ARAMID YARN
Para-aramid belongs to the aromatic polyamide family. The full name is poly(p-phenylene terephthalamide), abbreviated as PPTA or Aramid-II.
Due to its good characteristics in high strength, low density, low elongation at break, high modulus, non-conductive, good corrosion resistance, low thermal shrinkage, fire resistance and cut-proof. It is widely used in:
- building and bridge construction
- tire cord and fabrics
- hoses and belts
- optical fiber cables
- high-strength ropes
