Effects of testing parameters on the mechanical properties of polypropylene random copolymer

摘要

The effects of temperature on the impact resistance and hardness of polypropylene random copolymer are studied for a wide range of temperatures. The variations in the mechanical properties with a wide range of strain rates are also evaluated. Finally, the variations in mechanical properties as a function of time after production are studied.
