Thermo Scientific HAAKE PolyLab OS with RheoMix

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.
