An insulating resin composition that allows a reduction in the amount of spatial electric charges accumulated in an insulating layer, whereby dielectric breakdown is less likely to occur. This insulating resin composition 1 contains at least an antioxidant and a base resin including an unmodified polyolefin resin and a modified polyolefin resin modified by a molecule having a polar group. The modified polyolefin resin is modified by at least one selected from unsaturated dicarboxylic anhydride derivatives, unsaturated dicarboxylic anhydrides, and unsaturated dicarboxylic acids, which are each a molecule having a polar group. The base resin has a so-called island-in-sea structure in which a second phase 12 containing the modified polyolefin resin is present in a first phase 11 containing the unmodified polyolefin resin. The second phase has an average diameter of 2 μm or less.

Methods of depolymerizing polyolefin-based material into useful petrochemical products using supported metal oxides and heat are described. The supported metal oxides improve the depolymerization reaction by decreasing the half time for the depolymerization, which results in a higher depolymerization rate and a shorter residence time in the depolymerization unit, allowing for a predictable depolymerization reaction, and decreasing the branching or aromatic formations in the product.

Provided is a system, process, and method for the recycling of waste plastics. The recycling system, process, and method may comprise sorting of comingled waste. The sorting of comingled waste may include sorting into, for example, like polymer groups or families of plastic materials. The recycling system, process, and method may comprise processing of a sorted waste, including processing of the sorted plastic waste. The processing of the sorted plastic waste may include grinding and mixing, a supercritical or subcritical fluid treatment and sterilization, and extrusion to create and provide a homogenous precursor plastics blend. The precursor plastics blend may then be further extruded and refined to remove water and other low molecular weight material, and may be customized with additives to provide a value-added recycled plastic material. The additives may include colorants, flame retardants, fillers, fiber, identifiers, and the like, and may be combined in a ratio with virgin plastics, to impart specific properties on the value-added recycled plastic material based on its subsequent use in remanufacture and tracking. One or more of the recycling steps or phases may provide at least one of speed, accuracy, or cleanliness and minimization of human contact with waste materials.
