Abstract
A molding based on a monolithic organic aerogel has a density in the range from 60 to 300 kg/m3 and a thermal conductivity in the range from 12 to 17.8 mW/m*K. The molding based on a monolithic organic aerogel has more than 30 vol.-% of pores with a diameter of less than 150 nm, and more than 20 vol.-% of pores with a diameter of less than 27 nm, based on the total pore volume. A process can be used to prepare the molding by compression.
Claims13
