When a plasticizer is added to a polymer, it disrupts the regular packing of polymer chains, resulting in reduced crystallinity. This causes the material to become more flexible and softer, thereby lowering its Tensile Strength (TS) and increasing its Elongation at Break (U1B).

When a Plasticizer Is Added to a Polymer, the Overall
