Hollow plastic microspheres made from thermoplastic or thermosetting plastic compositions are described. The hollow plastic microspheres can be used as filler materials in plastics, in plastic foam compositions and in concrete and asphalt compositions. The hollow plastic mircospheres can be made from low heat conductivity plastic compositions and blown with a low heat conductivity gas and used to make improved insulation materials and composites and insulating systems. The hollow plastic microspheres can be made to contain a thin transparent or reflective metal coating deposited on the inner wall surface of the microspheres by adding to the blowing gas small dispersed metal particles and/or gases of organo metal compounds and decomposing the organo metal compounds. The hollow plastic microspheres can also be made in the form of filamented plastic microspheres with a thin plastic filament connecting adjacent plastic microspheres.
