The Properties of Tannery Waste Addition as a Filler Based on Two Types of Polymer Matrices: Poly(Butylene Adipate-Co-Terephthalate) (PBAT) and Poly(Butylene Succinate) (PBS)

Table 2

Mechanical properties of neat PBAT, neat PBS, PBAT/WBL composites, and PBS/WBL composites after the biodegradation test.

Neat PBAT				Did not break
PBAT_5WBL				Did not break
PBAT_10WBL				Did not break
PBAT_15WBL				26.8 ± 0.7
Neat PBS				3.9 ± 0.7
PBS_5WBL				5.6 ± 0.6
PBS_10WBL				4.5 ± 0.3
PBS_15WBL				3.8 ± 0.2
