During processing high temperatures and the presence of a nucleophile such as water lead to the degradation of polyamide.
This causes a decrease in polymer molecular mass and an increase in polymer end-groups. This finally results in a decline of the mechanical properties of the final product. It is possible to delay the onset of link decomposition by adding stabilisers.
The PolyLab system offers a quick and reliable method of examining the influence of stabilisers on material processing characteristics.
