Preparation and characterization of novel bio-based polyamide 5.6 composites as sustainable alternatives to petroleum-derived polyamide 6.6

In the pursuit of sustainable solutions, this study investigates the potential of bio-based polyamide 5.6 (PA56) as a promising alternative to petroleum-derived polyamide 6.6 (PA66). Novel composites of PA56 and PA66 were prepared with the incorporation of glass fibers and flame retardant additives by twin screw extruder. Subsequently, these composites were subjected to comprehensive characterization to determine their performance. The physical, mechanical, rheological, thermal, and flammability properties of PA56 composites were investigated and compared with those of PA66 composites with the same formulations. This article aims to unveil the remarkable potential of bio-based PA56 composites in industrial applications. The results showed that bio-based PA56 exhibits comparable, and in some cases superior, performance to PA66 while offering the added advantage of environmental sustainability. The findings suggest that bio-based polyamide 5.6 can serve as a sustainable alternative to petroleum-derived polyamide 6.6, contributing to a greener future in industrial applications. Highlights: Bio-based PA56 exhibits comparable properties to petroleum-derived PA66. Incorporation of glass fibers and flame retardants enhances the properties of PA56. Findings propose PA56 as a sustainable alternative to PA66 in various applications.
