Element O-03A is a composite material based on bimodal polyethylene for optical cables, manufactured according to TU 20.16.10–001-88028259-2024
Element O-03A composite material is designed for applying insulation, sheaths and protective covers to cables by extrusion. Natural color composition. Element O-03A is specially developed and tested on optical cables and communication cables. It is characterized by excellent resistance to thermal-oxidative and photo-oxidative aging, easy to process and apply. Analogue of the Borealis HE 3366 brand.
