- Polyamides in particular partially crystalline polyamides, are frequently used as materials for moldings which are exposed during their service life to elevated temperatures over an extended period of time.
- materials are sufficiently stable against the resulting thermal oxidative damage, especially for applications in the engine compartment of motor vehicles.
- thermal oxidative damage see: P. Gijsman, e-Polymers, 2008, no. 065.
- glass fiber reinforced polyamide 66 compounds have been established in the automotive industry for the production of high thermal stress products, where "high temperature” means temperatures in the range of 180 ° C to 240 ° C, temperatures that may occur in the engine compartment of motor vehicles with internal combustion engines today,
