Element P-03 is a composite material based on high-density polyethylene (LDPE), produced in accordance with TU 20.16.10–001-88028259-2024
Element P-03 is designed for applying insulation, sheaths and protective covers to cables using the extrusion method. Element P-03 is characterized by resistance to thermal-oxidative aging during processing and operation, as well as to photo-oxidative aging during operation.
A special feature of Element P-03 is its increased processability in a high range of application speeds.
