Cross-linked polyethylene (XLPE) is one of the most popular insulation materials used in the production of medium and high voltage cables (MV, HV). This article presents the results of research carried out on two types of commercially used insulation materials, modified with the addition of organophilic phyllosilicate (CLOISITE C20A)and halloysite nanotubes (HNTs). The influence of fillers on the mechanical properties of insulating materials is discussed as a potential mechanism for increasing their resistance to the phenomenon of water-tree. SEM and XRD analyses were performed to investigate the morphology and DSC for comparing phase transitions. Mechanical and functional properties for different concentrations of nanofillers, such as their hybrids, were also investigated.

This paper presents the results of the mechanical recycling of post-production automotive coverings. Shredded carpet waste was used to obtain new systems based on thermoplastic polymer materials, in this case linear low density polyethylene (LLDPE). As automotive carpet waste, we used a material composed mainly from polyamide 6, chalk, polypropylene. Optical microscopy and scanning electron microscopy characterized the structure of both the automotive lining and finished materials. The dependence of the mechanical properties and thermo-oxidative stability on the mutual content of the components was investigated.
