AbstractThe durability of polyvinylchloride (PVC) at static and cyclic loads during establishing of tensile and flexural strength is studied. It is found out that bulk static and cyclic durability can be described by a kinetic equation assuming that the tension changes the temperature‐energy factor. During testing of tensile strength it is established that the maximum deformation at break depends upon the tension of loading in an elaborate way with the existance of a peak at 32 MP
