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
  • This material data has been provided by Matmatch.

    All metrics apply to room temperature unless otherwise stated. SI units used unless otherwise stated.
    Equivalent standards are similar to one or more standards provided by the supplier. Some equivalent standards may be stricter whereas others may be outside the bounds of the original standard.
