Element P-04 is a composite material based on high-density polyethylene (LDPE), produced according to TU 20.16.10–001-88028259-2024
Element P-04 is designed for applying insulation, sheaths and protective covers to cables using the extrusion method.Element P-04 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-04 is its increased Shore D hardness value. Element P-04 is an analogue of 153-10KM
