What stress category does PE 80 belong to?

PE 80 is categorized under High Stress due to its material properties, which allow it to withstand significant pressures and temperatures when utilized in applications like piping systems. PE 80 refers to a specific type of polyethylene with a minimum required stress rating of 8 MPa, which indicates its capability to handle higher operational stresses compared to lower grades.

In contrast, other stress categories such as Low Stress or Medium Stress are associated with materials or applications that require reduced levels of stress and are typically made from materials that do not have the same high-pressure tolerance. Ultra High Stress designations apply to materials with even stricter performance criteria, which would exceed the capabilities of PE 80. Therefore, categorizing PE 80 under High Stress accurately reflects its intended use in demanding environments where it can provide durability and resistance to failure under load.
