| Abstract: | This paper studied on the effectiveness of nucleating agent to the mechanical properties and thermodynamic properties of the polypropylene monopolymer, V30G. The results indicated that when the 0.2% nucleating agent A was put into use, the tensile strength of the plastic samples was increased by 32%, the flexural strength and the flexural modulus of the plastic samples increased separately by 70% and 74%, as well as thermal deformation temperature increased by 62%. Therefore, the rigidity and thermodynamic properties of materials increased greatly. |
