Abstract
Rigid foam insulating products and processes for making such insulation products are disclosed. The foam products are formed from a polymer, a blowing agent, and nano-graphite. The nano-graphite has a size in at least one dimension less than about 100 nm and, in exemplary embodiments may be an intercalated, expanded nano-graphite. In addition, the nano-graphite may include a plurality of nanosheets having a thickness between about 10 to about 100 nanometers. The nano-graphite acts as a process additive to improve the physical properties of the foam product, such as thermal insulation and compressive strength. In addition, the nano-graphite in the foam controls cell morphology and acts as a nucleating agent in the foaming process. Further, the nano-graphite exhibits overall compound effects on foam properties including improved insulating value (increased R-value) for a given thickness and density and improved ultraviolet (UV) stability.
