The names PE80 and PE100 are based on the long-term strength of the corresponding material and are referred to as the minimum required strength (MRS). The minimum required strength (MRS) of the PE80 pipe is 8 MPa, while the MRS of the PE100 pipe is 10 MPa. PE100 raw material is an improved raw material than PE80, and its performance is higher than that of PE80.
PE100 has advantages over PE80 at low temperatures since it is extremely crack resistant down to -30°C. MDPE pipe is only made from PE80 material and HPPE pipe is only made from PE100 material. HDPE pipe can be made from either PE80 or PE100.
