Effect of talc on (a) tensile strength and modulus (b) elongation at break and impact strength of neat PLA and PLA/talc. The main drawback of PLA is brittleness while SR is highly flexible and more ductile than neat PLA. FIGURE 2(a) illustrates that increasing SR content reduced the brittleness of PLA.
