In the present study, three different commercial bio-based polyamides (bio-PAs), namely polyamide 610
(PA610), polyamide 1010 (PA1010), and polyamide 1012 (PA1012), were processed by profile extrusion
with an annular die. These aliphatic homopolyamides, also known as “green nylons”, are industrially
produced by polycondensation reaction of diamines and dicarboxylic acids that are partially or fully
obtained from naturally occurring castor oil. The profile-extruded bio-PA tubes were characterized and
compared in terms of their thermal, thermomechanical, and mechanical properties and also water uptake.
Resultant comparative evaluation indicated that both the methylene-to-amide (CH2/CONH) ratio
and the crystallinity degree of the bio-PAs played the main role in determining the performance of the
tubes. Due to significant differences in their CH2/CONH ratio, the PA610 tubes showed the highest
thermal properties while the tubes made of PA1012 presented the highest flexibility and lowest water
uptake. Interestingly, the fully bio-based PA1010 tubes offered the most balanced and enhanced engineering
performance, which was ascribed to the high crystallinity achieved during profile extrusion. The
here-developed bio-PA tubes can fulfil demanding technical requirements and these also certainly
represent a sustainable answer to the rising demand for new high-performance biopolymers for engineering
applications. [-]
