Abstract
Low-density thermoplastic expandable microspheres are disclosed. Various low-density structures, in particular, sandwich panels, based on foam prepared from the low-density microspheres, are also disclosed. Process of preparing low-density polymeric microspheres, per se, and the corresponding low-density structures, based on the microsphere foam, are also disclosed.
Claims15
A composition of matter comprising a foam, said foam comprising polymeric microspheres, said polymeric microspheres further being expanded and further being fused to each other in at least one portion thereof, wherein said foam is characterized by a density below 15 kg/m3, and wherein said density is characterized as being a uniform density, said uniform density being characterized as having at least 90% of said foam with densities that vary within a range of less than 15%, said microspheres are limited to size variation of less than 15%, said microspheres are coated with multiwall carbon nanotubes at said carbon nanotubes density of 1.5 gr/cc to 2.5 gr/cc.
