机械性能
聚丙烯由于其高结晶度和规则的结构，具有优异的机械性能。聚丙烯的力学性能值高于聚腈，但在塑料材料中仍属低品种，其拉伸强度仅能达到30mpa或稍高
拉伸强度只能达到30 MPa或稍高。各向同性指数较高的聚丙烯具有较高的拉伸强度，但材料的冲击强度随着各向同性指数的增加而降低，但随着等值线的增加，材料的冲击强度降低，但在一定值后没有变化
温度和加载速率对聚丙烯的韧性有很大影响。当温度高于玻璃化转变温度时，冲击损伤为韧性断裂，低于玻璃化转变温度时为脆性断裂，冲击强度值大幅度降低。提高加载速率，可以使韧性断裂向脆性断裂转变的温度升高。聚丙烯具有优异的抗弯曲疲劳性能，其产品在室温下可弯曲106次而无损伤。然而，在室温和低温下，由于其分子结构的高度规整性，冲击强度较差。聚丙烯的突出性能是其抗弯曲疲劳性，通常被称为“弯曲橡胶”

Mechanical properties
Polypropylene has excellent mechanical properties due to its high crystallinity and regular structure. The value of the mechanical properties of polypropylene is higher than that of polyZene, but it is still a low species among plastic materials, and its tensile strength can only reach 30 MPa or slightly higher.
The tensile strength can only reach 30 MPa or slightly higher. Polypropylene with a higher isotropic index has a higher tensile strength, but the impact strength of the material decreases as the isotropic index increases, but decreases to The impact strength of the material decreases with increasing isograms, but does not change after a certain value.
Temperature and loading rate have a great influence on the toughness of polypropylene. When the temperature is higher than the glass transition temperature, the impact damage is ductile fracture, and below the glass transition temperature is brittle fracture, and the impact strength value is greatly The impact strength value decreases greatly. Increase the loading rate, can make the ductile fracture to brittle fracture transition temperature rise. Polypropylene has excellent resistance to bending fatigue, its products at room temperature can be bent 106 times without damage. However, at room temperature and low temperature, the impact strength is poor due to the high degree of regularity of its molecular structure. The outstanding property of polypropylene is its resistance to bending fatigue, which is commonly known as “bending rubber”.
