Polyamide 6 - Nylon 6 - PA 6

Polymer Type



Easier to process than Nylon 6/6 (castable), may be reaction injection moulded.  Has lower mould shrinkage than Nylon 6/6 with good fatigue resistance. Useful improvement in stiffness can be obtained by inclusion of glass fibres, unlike acetals.


Highest rate of water absorption and highest equilibrium water content.  Lower strength & stiffness than Nylon 6/6.  Higher stick slip than Acetal or PBT.


Gears, cams, rollers, bearings, nuts and bolts, power tool housings, electrical connectors, combs, coil formers, fuel tanks for cars, kitchen utensils.

NOTE: Generally similar applications to Nylon 6/6.  Choice between the two polymers is often made on non-technical grounds, e.g. local availability, price or familiarity.

    Can you mould this material through a hot running manifold or is it better to use a cold runner with a spruce ?

  2. Rayudu Neeraja Rayudu Neeraja India says:

    Nylon 6 trefoil clamp is suitable at working temperature  -50 degree centigrade
