VACUUM INSULATION MATERIAL

摘要

A vacuum insulation material includes a core material, and a wrapping member configured to wrap the core material, wherein the wrapping member comprises an outermost layer externally exposed, a barrier layer located beneath the outermost layer and having at least two laminated polymer layers, each polymer layer having an inorganic layer metalized thereon, and a thermal bonding layer located beneath the barrier layer and contacting the core material, wherein the inorganic layers metalized on the polymer layers, respectively, are separated from each other, at least one of the inorganic layers being more than 600Å in thickness.
