Fig. 4: Comparison of mechanical and thermal properties of BM-plastic with commercial plastics.

a Tensile stress-strain curves of ABS, HIPS, PA66, PMMA, and BM-plastic. All samples with thickness of 1.00 ± 0.01 mm. b Comparison of tensile strength and modulus of ABS, HIPS, PA66, PMMA, BM-plastic. c Investigating the tensile strength and work of fracture between BM-plastic, commercial plastics, and bioplastics. d Optical images from high-temperature resistance experiments conducted on BM-plastic and several commercial plastics. All samples with thickness of 1.00 ± 0.01 mm. e Comparison of the storage modulus between BM-plastic, ABS, HIPS, PA66, and PMMA. These curves are obtained through DMA testing. f Comparative analysis of dimensional change values of BM-plastic relative to plastics such as ABS, HIPS, PA66, and PMMA. g Comparison of impact strength between BM-plastic, ABS, HIPS, PA66, and PMMA. Values in (b and g) represent their means ± SDs from n = 5 independent samples.
