Streszczenie
Polyethylene plastics are used in various branches of the global industry, mainly in extrusion and injection
technology, in form of pipes, foils, various types of packaging. The properties of polymer materials largely depend on the
conditions of use: temperature, load time, type of deformation, atmospheric conditions, UV radiation, as well as design
solutions, parameters of the soil in which the pipeline works, pressure from the soil and external forces, e.g. car traffic. The
above-mentioned factors can significantly affect the chemical, physical, mechanical and aesthetic properties of polymer
materials. The paper presents DSC measurements for polyethylene, thermal analysis of dynamic mechanical
properties, and results of experimental examinations of pipe loading with the forces of 500N, 1000N, 1500N and 2000N
acting on the ground. Using resistance strain gauges at equal intervals on the pipe, lateral strains on the lower and upper
surface of the pipe were measured at the moment of loading and after 10 minutes.
