POLYMER FOAM INSULATION STRUCTURES HAVING A FACING LAYER OF A POLYLACTIDE RESIN
Thermal insulation structures include a polymer foam layer adhered to a non-cellular sheet of a polylactide resin. The polylactide resin is a surprisingly good barrier to the diffusion of atmospheric gases into and blowing agents out of the foam layer. Accordingly, the diffusion of atmospheric gases...

Summary: | Thermal insulation structures include a polymer foam layer adhered to a non-cellular sheet of a polylactide resin. The polylactide resin is a surprisingly good barrier to the diffusion of atmospheric gases into and blowing agents out of the foam layer. Accordingly, the diffusion of atmospheric gases and the blowing agents is retarded substantially. This greatly reduces the loss of thermal insulation capacity of the structure due to the replacement of the blowing agent with atmospheric gases. |
