PA6+GF, PA66+GF

PA6 and PA66 are very similar materials, also when reinforced. Let’s handle PA6+GF first and then see the difference to PA66.

PA6+GF

Why choose?

  • Commonly used, relatively inexpensive material, easy to find references.
  • Good choice if your product is exposed to elevated temperatures, rattling, oil, and dirty hands.
  • Nice surface finish (on other than polished surfaces).

Why not choose it?

  • PA6 absorbs moisture which might decrease its strength and modulus of elasticity almost by half.

Typical applications:

  • Different types of levers that require high strength and stiffness
  • Boat cleats
  • Garden tool handles

PA66+GF

Why choose (over PA6+GF)?

  • PA66 offers slightly better thermal resistance than PA6.
  • PA66 absorbs less moisture than PA6.

Why not choose?

  • Slightly higher price. If PA6+GF fulfills your requirements it does not make sense to pay more.
  • Moisture absorption problem is not fully eliminated by choosing PA66 instead of PA6. You might consider using PBT+GF instead.

Typical applications:

  • Spatulas and other kitchen utilities
  • Bodies of electric tools
  • Biking gear
  • Automobile parts
