Property examples of several self-lubricating polyamide grades

Thermoplastic neat polyamides 6 and 66 at equilibrium with a 50% RH environment have rather low moduli involving high strains for moderate loading. Consequently creep moduli 

These results relate to a few grades only and cannot be generalized. 

The dynamic fatigue can be fair or good for well-adapted grades if care is taken to limit the strains by restricting the stresses to values in keeping with the low modulus. 

For a given grade of neat impact-modified PA 6, failure occurs after 2 million cycles under 14 MPa. 

Polyamide is naturally sensitive to light and UV. It must be protected by addition of anti-
