Long Fiber Moisture Resistant Nylons

Complēt™ Moisture Resistant Nylons 

Environmentally Stabilized Nylon 6 and 6/6 Long Fiber Composites 

Complēt™ moisture resistant long fiber reinforced nylons, in PA 6 and 6/6 matrices, have slowed moisture uptake, which provides a more stable and predictable mechanical property profile during real world use. 
If you require consistent performance in a range of climates, Complēt moisture resistant nylons are a cost-effective alternative to less hygroscopic specialty nylons for applications that intermittently experience moisture-rich environments. 
Providing conditioned structural performance at levels between standard and specialty nylons, these composites are ideal for lightweighting initiatives in the automotive or powersports industries that rely on dependable materials with exceptional load carrying and fatigue resistant capabilities.

  • Gradual moisture uptake to maintain structural properties longer in humid and aqueous environments for more consistent performance
  • Performance proportional to specialty nylons at less cost
  • Better dimensional stability and easier processing at higher fiber content levels than standard nylons
  • Glass fiber formulations provide enhanced surface aesthetics free of visible fiber
  • Better flow characteristics at high fiber content levels
