The temperature dependences of tear strength for the main Borealis polyethylene grades were studied. It is shown that along with the common areas where the strength decreases with temperature, there are temperature, regions where the temperature dependence is weakly expressed or there is a maximum tear resistance associated with orientational hardening, similar to the maximum in materials of PE-RT II type.
