Ki te whakatauritea ki ngā ngongo tuku, ka taea e ngā ngongo ngongo te tu atu i te pēhanga kino me te pēhanga pai, ā, ka taea te mahi tonu i raro i ngā āhuatanga piko hihiri. He ngongo rapa nui ēnei mō ngā mīhini keri.

Ko ngā āhuatanga matua o te Ngongo Momi ko te ātete pai ki te kakahu, te ātete ki te huarere, me te ngāwari.

Ko te pēhanga mahi mōrahi o ngā Ngongo Momi ko te -0.1 MPa, ā, ko te pēhanga whakamātautau ko te -0.08 MPa. Kei te wātea hoki ngā Ngongo Momi me ngā whakaritenga motuhake, pēnei i ngā mea ka taea te tu atu i ngā pēhanga mai i te -0.1 MPa ki te 0.5 MPa. He pai ngā Ngongo Momi mō ngā pāmahana taiao mai i te -20℃ ki te 50℃, ā, he pai hoki mō te kawe i ngā ranunga wai (wai moana rānei), paru, paru, uku me te onepu, mai i te 1.0 karamu/cm³ ki te 2.0 karamu/cm³ te taumaha motuhake.
