ʻO nā resins phenolic no nā huahana friction material series, no nā ʻano hana noiʻi e pono ai, loaʻa nā pono aʻe:::
nā resins phenolic kumu nui me ka hāʻawi ʻana i ka maikaʻi, kūpaʻa maikaʻi a me ka ikaika paʻa kiʻekiʻe;
ʻO nā resins phenolic i hoʻololi ʻia i hoʻololi ʻia me ka hāʻawi ʻana i ke kaumaha molecular haiki, ka papa kuhikuhi i hoʻomalu ʻia, ka maʻalahi maikaʻi, etc.
Hoʻohana nā resins phenolic i hoʻololi ʻia i nā mea a me nā kaʻina hana kūikawā e hāʻawi i ka huahana i nā waiwai kūʻokoʻa, me ka hāʻawi ʻana i ke kaumaha molecular haiki, ka mana index koʻikoʻi, ka hana hana kūikawā, etc.
Hoʻohana nui ʻia nā resins wai no nā mea friction i ka hana pulu o nā mea friction, nā ʻili paʻa a me nā huahana ʻē aʻe, me ka hāʻawi ʻana i ke kaumaha molecular haiki, ka mana index index, ikaika kiʻekiʻe a me ka hoʻohui haʻahaʻa o kēia huahana;
