injection molding parts usually to its tough property and rigid property, has what is the difference 呢?

tough property is material in fracture front absorption property deformation and fracture can force, table/sheet material resistant cracks expand property can, usually can use engineering force -应变曲线 lower 面积 衡 amount, 面积越 large, tough property high, resistant fracture can force strong/high, has force 应变曲线 横纵坐标（即 strong/high degree and 应变）都 comparison large 时候, tough property high, if strong/high degree low, make property very large, tough property 也不会太 high. therefore tough property is strong/high degree and property comprehensive indicators.

也就 is 说, tough property is material bad front absorption can amount how much, and property deformation can force, and versus for is property. therefore, in tensile upper deformation large, fracture large is tough property good. usually can use impact strong/high degree evaluation, is impact strong/high degree generally use fracture table/sheet 示.

塑 property is types in certain types to 定载荷 lower,材 material generate deformation material features, for large more engineering material 说,当 its force low ratio/proportion 极限时,应 force 一应变关系 is property. another, large more material in its force low 于屈服点时, performance is elastic property is, is 说, 当移走载荷时, its 应变也完 full 消失. commonly used elongation and shrinkage rate amount property.

tensile strength: and can related, for polymer/macromolecule 说, tensile bad large more 数情况并不 is for 键 破 bad, is separation between slip and poly 集状态 改变, therefore main/primary and separation force and crystallization degree related.

rigid property usually is through flexural strength amount. polymer/macromolecule usually from strong/high low, hard soft, tough large to evaluation.
