Description

Twaron® is a para-aramid, high-performance yarn which combines the following characteristics:


  • High strength: excellent strength-to-weight ratio
  • High modulus
  • High dimensional stability: very low creep, small negative thermal expansion coefficient
  • Excellent thermal stability: usable across a wide range, no melting point, high heat stability, low heat conductivity
  • High cut resistance
  • Good chemical resistance
  • Low flammability
  • Electrically non-conductive
  • Long, well-characterised lifetime under static and dynamic loads
