Polyamide 6.10 (PA6.10) is similar in terms of mechanical, thermal and electrical properties to the cheaper PA6, but has significantly lower moisture absorption. It is used for components for which certain specification requirements justify the higher price. PA6.10 is often chosen, for example, on account of its high impact resistance, chemical resistance and retention of dimensions under most conditions. Typical applications are precision bearings and transmissions or brush fibres.

PA6.10 is suitable for temperatures of up to 110°C, but at higher temperatures thermal ageing occurs quickly. By adding certain minerals or glass fibre, a wide spectrum of types becomes available, each with its own particular mechanical specifications. The absorption of moisture, i.e. 0.4% at 23°C/50% RH and 3% after saturation in water at 23°C, is less than attainable with PA6 or PA6.6. This results in higher electrical insulation value and mechanical properties and also greater retention of dimensions of injection-moulded products.

PA6.10 is excellently resistant to oils, greases, aliphatic hydrocarbons and alkaline substances. Like all polyamides, PA6.10 cannot withstand strong acids or chlorinated hydrocarbons. Chlorine salts can cause stress cracks.

The mechanical properties are virtually the same as those of PA6, although the absorption of moisture has far less influence. Moreover, this makes the material far more dimensionally stable and less sensitive to cold deformation.
