The mechanical properties are tensile strength, proof stress, Young's modulus of elasticity, flexural strength and modulus of rigidity. Do you need the formula for these mechanical properties?

Mechanical Properties at 23 °C

Tensile Strength, Yield at 23° C -----> 31 - 45 MPa

Tensile Strength, Break at 23° C -----> 18 - 22 MPa

Elongation, Yield =10 - 12 %

Elongation, Break = 50 - 145 %

Tensile Modulus at 23° C -----> 1950 MPa

Flexural Modulus ------> 1350 - 1800 MPa
