Abstract
A physically crosslinked, closed cell continuous foam structure derived from recycled metallized polyolefin material; polypropylene, polyethylene, or combinations thereof, a crosslinking agent, and a chemical blowing agent is obtained. The foam structure is obtained by extruding a structure comprising a foam composition, irradiating the extruded structure with ionizing radiation, and continuously foaming the irradiated structure.
Claims12
A foam structure comprising:
- 5-75 wt. % recycled metallized polyolefin material;
- 25-95 wt. % polypropylene, polyethylene, or combinations thereof, wherein a density of the foam structure is 20-250 kg/m3.
A laminate comprising:
- a first layer comprising a foam structure, wherein the foam structure comprises 5-75 wt. % recycled metallized polyolefin material;
- 25-95 wt. % polypropylene, polyethylene or combinations thereof, wherein a density of the foam structure is 20-250 kg/m3;
- and
- a second layer.
A thermoformed article comprising a foam structure, wherein the foam structure comprises 5-75 wt. % recycled metallized polyolefin material;
- and 25-95 wt. % polypropylene, polyethylene, or combinations thereof, wherein a density of the foam structure is 20-250 kg/m3.
A flooring system comprising:
- a top floor layer;
- a sub-floor layer;
- and
- at least one underlayment layer disposed between the sub-floor and top floor layers, wherein at least one underlayment layer comprises a foam structure, wherein the foam structure comprises 5-75 wt. % recycled metallized polyolefin material;
- and 25-95 wt. % polypropylene, polyethylene, or combinations thereof, wherein a density of the foam structure is 20-250 kg/m3.
