Abstract
Compositions and methods for making polymeric foams containing nanocellular domains are provided. The nanocellular domains within the polymer foam increase the R-value of the polymer foam product and improve thermal insulation properties. Carbon dioxide-based blowing agents can be used to form polymeric foams with nanocellular domains. Polymeric foams with nanocellular domains can be produced on production scale equipment in quantities suitable for large scale applications.
Description
[0001] related application [0002] This application claims priority and all benefit of U.S. Provisional Patent Application Serial No. 62 / 244,252 filed October 21, 2015 for METHODS OF MANUFACTURING FOAMSCOMPRISING NANOCELLULAR DOMAINS, the entire disclosure of which is incorporated herein by reference in its entirety. technical field [0003] The present disclosure relates to a composition and method of making polymeric foam. Background technique [0004] It is known that the total heat transfer in a typical foam can be broken down into three components: heat conduction from the gas (or blowing agent) vapor, heat conduction from the polymer solids (including the cell walls and scaffolds of the foam), and heat transfer across the foam Thermal Radiation of Cells [Schutz and Glicksman, J. Cellular Plastics, March-April, 114-121 (1984)]. Reducing the foam cell size to approximately the mean free path of gas molecules (typically, less than about 100 nm) results in a significant ...
