Polyamide 6 - Nylon 6 - PA 6

Polymer Type

Thermoplastic

Advantages

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.

Disadvantages

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

Applications

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 ?
