Plastics are deemed more critical than other construction materials due to a physical phenomenon known as “creep”. This phenomenon is illustrated in the following graphs that highlight elongation over time of a specimen subject to a stress test at two different temperatures of 23°C and 125°C. Considering that the rupture load of the material is 50 MPa, it is clear that safety module 10 is essential to guarantee correct use of the product over time.
