Ma microspheres agalasi, omwe amadziwikanso kuti Hollow Glass Microspheres (HGM), ndi mtundu wa zinthu zopepuka, zopanda chitsulo, komanso zogwira ntchito zambiri. Amapangidwa makamaka ndi borosilicate ndipo amapangidwa kudzera mu kutentha kwambiri pa kutentha kuyambira 700 mpaka 800℃. Ndi kukula kwa tinthu tomwe nthawi zambiri timakhala pakati pa ma micrometer 10 ndi 250 komanso makulidwe a khoma la ma micrometer 12, ma microspheres awa ndi a micron ndipo ali ndi makhalidwe abwino kwambiri monga kupepuka, mphamvu yayikulu, kutchinjiriza kutentha, komanso kukana dzimbiri.

Ma microspheres agalasi ali ndi ntchito zosiyanasiyana chifukwa cha mawonekedwe awo apadera. Nthawi zambiri amagwiritsidwa ntchito ngati zodzaza zinthu monga fiberglass, komwe amatha kuchepetsa kulemera, kulimbitsa kuuma, kulimba, komanso kupindika, komanso kukonza kukhazikika kwa mankhwala ndi kubwezeretsanso. Kuphatikiza apo, amatha kusintha zigawo zodula za utomoni, kuchepetsa ndalama zopangira. Mu zinthu zophatikizika zokonzera, monga putty, amapereka zopepuka, zolimba, zosavuta kugwiritsa ntchito, zochepa kuchepera, komanso kukhazikika bwino.

Ponseponse, magalasi ang'onoang'ono ndi zinthu zogwiritsidwa ntchito mosiyanasiyana komanso zamtengo wapatali zomwe zingatheke kupangidwanso ndikugwiritsidwa ntchito m'mafakitale osiyanasiyana.
