In the manufacture of impregnating masses for paper cable insulation, non-oxidized polyethylene waxes of medium viscosity (200-300 MPa*s at 1400C) are used. In these compositions, the wax acts as a thickener of the impregnating mass and regulates its viscosity.
Polyethylene wax has found wide application in the production of polyethylene cable compositions, especially difficult-to-burn halogen-free ones. When the polyethylene is highly filled with aluminum or magnesium hydroxide, the composition becomes solid. To give it plasticity and facilitate workability, from 5 to 8% of polyethylene wax is added. A similar effect is shown in the manufacture of electrically conductive cable compositions (example of use patent of the Russian Federation-2394292 electrical insulation composition).
Also, polyethylene waxes are used in the manufacture of hydrophobic filler for fiber optic cable. The presence of polyethylene wax in these polymer compositions leads to better adhesive properties and complete combination with cable insulation. At the same time, it meets all IOC standards. (example of use patents of the Russian Federation-2208854, the Russian Federation-2257395).
Polyethylene waxes are also widely used in the production of cable insulation from PVC plastics.
