Abstract (en)
[origin: WO2007024246A1] An impregnated foam comprises a flexible cellular foam impregnated with a chemical agent in which a plurality of particles having dimensions of 100 micrometers or less are dispersed. The foam can be compressed between two structural elements to form, e.g., a joint sealant; an expansion joint; a closure; a gap filler; a gasket; or a sealing, insulating, acoustical or anti-vibration sheet or blanket. Inclusion of the fine particles enables the use of less chemical agent or a lower degree of compression to obtain the same sealant performance as previous impregnated foams. Figure 1 is a magnified view of the microstructure of foam impregnated with a chemical agent in which microparticles are dispersed.
