Benefits

  • Relatively high fatigue strength.
  • Stiffer than PEHD.
  • Retains its mechanical properties better at high temperatures than PEHD.
  • Excellent dielectric properties.
  • Low density (floating).
  • Chemical resistance similar to polyethylene, but not the same tendency to stress cracking due to. surrounding medium.
  • Reinforced grades have a stiffness similar to unfilled nylon but at a lower price.
  • Mechanical and electrical properties are also maintained in water.
  • Non-toxic grades can be steam sterilized.

Restrictions

  • Becomes brittle below -20 ° C.
  • Degraded by UV radiation if it is not stabilized.
  • Attacked by oxidizing acids.
  • Thermal stability is reduced upon contact with copper.
  • Easier to glue together with other materials, such as wood and aluminum than with yourself.
