Hoʻopiha kiʻekiʻe: kiʻekiʻe kiʻekiʻe o ka spheroidization rate, controllable particle size distribution, hoʻokō i ka hoʻopiha piha kiʻekiʻe no ka silicone a me ka resin epoxy, e kiʻi i ka hui me ka haʻahaʻa haʻahaʻa a me ka mobility kiʻekiʻe;
High Thermal Conductivity: Ma muli o kona ʻano pōlele kokoke loa, hiki i ka mea hoʻopihapiha i hoʻohana ʻia i nā mea maka ke hoʻokō i ka hoʻoili wela multi-directional.ʻO ka ʻōnaehana hui pū ʻia i ke kūlana o ka hoʻopuehu maikaʻi, no laila, loaʻa nā huahana hope loa i ka conductivity thermal maikaʻi a me ka waiwai kino;
Haʻahaʻa Haʻahaʻa: Hoʻohālikelike ʻia me ka pauka maʻamau, hiki i ka hoʻohana ʻana i ka hoʻopiha piha spherical ke hōʻemi i ka abrasion o ka hui ʻana, nā mīkini hana a me nā mea hana ʻē aʻe, a laila hoʻolōʻihi i ke ola hana o nā mea pono.
