METHODS OF MANUFACTURING ARTICLES UTILIZING FOAM PARTICLES
Methods for manufacturing articles of footwear are provided. In various aspects, the methods comprise utilizing additive manufacturing methods with foam particles. In some aspects, the additive manufacturing methods comprise increasing the temperature of a plurality of foam particles with actinic radiation under conditions effective to fuse a portion of the plurality of foam particles comprising one or more thermoplastic elastomers. Increasing the temperature of the foam particles can be carried out for one or multiple iterations. The disclosed methods can be used to manufacturer articles with sub-regions that exhibit differing degrees of fusion between the foam particles, thereby resulting in sub-regions with different properties such as density, resilience, and/or flexural modulus. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present disclosure.

COMPOSITE ARTICLE FOR INSULATING APPLIANCE, APPLIANCE COMPRISING COMPOSITE ARTICLE, AND RELATED METHOD
A composite article and a method for insulating an appliance are disclosed. In general, the appliance is selected from the group of major, domestic or household appliances (e.g. ovens, stoves, ranges, etc.). The appliance has a first surface that defines a heating cavity, and a second surface opposite the first surface. The composite article comprises a backing layer spaced from the first surface, and an insulating layer sandwiched between the second surface and the backing layer. The insulating layer reduces heat transfer from the heating cavity to the backing layer (e.g. during use of the appliance). The insulating layer comprises a foamed silicone. The foamed silicone can be one formed via a hydrosilylation-curable silicone composition, a condensation-curable silicone composition, or a combination thereof. The insulating layer may comprise a foamed room-temperature-vulcanizing (RTV) silicone. The backing layer comprises a foamed polyurethane (PUR), a foamed polyisocyanurate (PIR), or a foamed PUR/PIR hybrid.
