求翻译：　通常，聚丙烯材料本身的机械性能距离工程结构件的要求差别很大，一般拉伸强度在20～30MPa之间，弯曲强度在25～50MPa之间，弯曲模量在800～1500MPa之间。是什么意思？

Typically, the mechanical properties of polypropylene material itself from the requirements of engineering structural components vary widely, generally in the 20 ~ 30MPa tensile strength between the bending strength between 25 ~ 50MPa in bending modulus between the 800 ~ 1500MPa.

Usually, the mechanical strength polypropylene material itself away from the requirements engineering structures differ greatly, and general tensile strength in 20 ~ 30, between MPa Flexural strength in 25 ~ 50, between MPa Flexural modulus in between 800 and 1,500 MPa.

　Usually, the polypropylene material itself mechanical property is away from the project structural element the request difference to be very big, general longitudinal strength between 20~30MPa, bending strength between 25~50MPa, curving module between 800~1500MPa.

　Typically, mechanical properties of pp material itself distance engineering structure requirements varied greatly, General tensile strength between the 20~30MPa and bending strength between 25~50MPa, between 800~1500MPa flexural modulus.

　Typically mechanical performance of polypropylene material itself distance engineering structure requirements vary, General tensile strength between 20~30MPa and bending strength between 25~50MPa, flexural modulus between 800~1500MPa.
