Accelerated climatic tests of extruded composites based on UHMWPE have been carried out. It has been established that stearic acid, used as a plasticizer, is washed out when exposed to climatic factors. At the same time, a significant degradation of the physical and mechanical characteristics of materials is observed. It has also been shown that the addition of a CO-4 stabilizer as an antioxidant improves the climatic resistance of materials based on UHMWPE, however, their fluidity and extrudability noticeably worsen.
