Effect of Thermoplastic Polyurethane on the Mechanical Properties and Structure of Poly(butylene terephthalate)/Thermoplastic Polyurethane Blend

Poly(butylene terephthalate) is a rigid polymer with poor elasticity and impact resistance. In this research, thermoplastic polyurethane is mixed with poly(butylene terephthalate) through injection molding to improve the impact strength and elasticity of the blend. The findings revealed that the blend had higher impact toughness but lower tensile and flexural strengths when compared to neat poly(butylene terephthalate).
