Closed cell materials

摘要

Fabrics made for watersports and outerwear apparel, tents, sleeping bags and the like, in various composites, constructed such that there is at least one metal layer, forming a radiant barrier to reduce heat loss via radiation, and insulating this metal layer from conductive heat loss, and a process for its manufacture.

主权项

1. An infra-red reflective composite comprising:
an outer layer comprising a foam material; an inner layer comprising a fleece material; a closed cell neoprene foam layer sandwiched between the outer layer and the inner layer, and at least one metal layer facing the closed cell foam layer, comprising a material selected from the group consisting of Al, Cu, Au, Zn, Mg, Ti, Ag, AL2O3, stainless steel, AgGe, CuZn, CuSn, CuAg, or CuAgSn; wherein the closed cell foam layer comprises a pattern of perforations through the closed cell foam layer, which create gaps that expose at least a portion of the metal layer; and wherein said perforations expose over 30% of a surface area of the metal layer.
