An vehicle interior sheet, particularly a vehicle interior sheet using a waste TPO composite sheet capable of preventing environmental pollution by recycling industrial waste, and a method of manufacturing the same includes manufacturing a powder by pulverizing a waste TPO composite sheet, manufacturing recycled TPO resin pellets by processing the powder using an extruder, and manufacturing a recycled TPO layer by subjecting the recycled TPO resin pellets to calendering or extrusion molding.

A composite material is formed by combining an expandable polymer having a charge with another polymer having an opposite charge to produce. In particular, the composite material can be prepared by combining the polymers with a medium such as and water, and expanding the mixture using a treatment that expands the mixture to produce, for example, insoluble porous foam-like composite

Embodiments of the disclosure relate to an optical fiber cable having at least one optical fiber, a cable jacket, and a foam layer. The cable jacket has an inner surface and an outer surface. The outer surface is an outermost surface of the optical fiber cable, and the inner surface is disposed around the at least one optical fiber. The foam layer is disposed between the at least one optical fiber and the cable jacket. The foam layer includes a polymer component having from 30% to 100% by weight of a polyolefin elastomer (POE) or thermoplastic elastomer (TPE) and from 0% to 70% by weight of low density polyethylene (LDPE). The foam layer has a closed-cell morphology having pores with an average effective circle diameter of 10 μm to 500 μm. Further, the expansion ratio of the foam layer is at least 50%.

A closed loop recycling process of manufacturing a foam part includes dispersing a filler material recycled from an additive manufacturing (AM) process in at least one foam reactant and pouring or injecting the at least one foam reactant with the filler material into a mold and forming the foam part. The foam part has a foam matrix with between 2.5 wt. % and 30 wt. % of the filler material. The filler material can be a recycled powder from a selective laser sintering process that is not graded (i.e., sized) before being dispersed in the at least one foam reactant. For example, the recycled powder can be a recycled polyamide 12 (rPA12) powder with an average particle diameter of less than 100 micrometers. Also, the least one foam reactant can be a polyol reactant and an isocyanate reactant such that a polyurethane foam matrix with recycled rPA12 filler material is formed.
