Pōmaikaʻi:

1. ʻO ka ikaika mechanical kiʻekiʻe, ka paʻakikī maikaʻi, ka tensile kiʻekiʻe a me ka ikaika compressive.ʻOi aku ka kiʻekiʻe o ka ikaika tensile kikoʻī ma mua o ka metala, a ua like ka ikaika compressive kikoʻī me ka metala, akā ʻoi aku ka liʻiliʻi ma mua o ka metala.ʻO ka ikaika tensile kokoke i ka ikaika hua, ʻoi aku ma mua o ʻelua mau kiʻekiʻe ma mua o ABS.ʻOi aku ka ikaika o ka hoʻopili ʻana o ka hopena a me ka vibration stress, a ʻoi aku ka kiʻekiʻe o ka ikaika o ka hopena ma mua o nā plastics maʻamau, a ʻoi aku ka maikaʻi ma mua o ka resin acetal.

2. He kūlana koʻikoʻi ke kūpaʻa luhi, a hiki i nā ʻāpana ke hoʻomau i ka ikaika mechanical mua ma hope o ke kulou mau ʻana.Hoʻohana pinepine ʻia ka PA i nā kūlana i ʻike maopopo ʻia ka hopena luhi o nā lima escalator maʻamau a me nā rim paikikala plastik hou.

3. Kiʻekiʻe softening wahi a me ka wela kū'ē (e like me ka nylon 46, kiʻekiʻe crystalline nylon i ka wela wela deformation kiʻekiʻe, hiki ke hoʻohana 'ia no ka manawa lōʻihi ma lalo o 150 ℃. Ma hope o aniani fiber hooikaika, PA66 i ka wela deformation wela o ka oi aku mamua o 250 ℃).

4. Ka ili maʻemaʻe, liʻiliʻi friction coefficient, aahu-pale.He lubricating ponoʻī a he haʻahaʻa ka walaʻau ke hoʻohana ʻia ma ke ʻano he ʻāpana mechanical movable.Hiki ke hoʻohana ʻia me ka ʻole o ka lubricant inā ʻaʻole kiʻekiʻe ka hopena friction;Inā makemake maoli ka lubricant e hoʻemi i ka friction a i ʻole ke kōkua ʻana i ka wela, hiki ke koho ʻia ka wai, ka aila, ka momona, a me nā mea ʻē aʻe.No laila, ma ke ʻano he mea hoʻouna, he lōʻihi kona ola lawelawe.

5. He mea kū'ē i ka corrosion, alkali a me ka nui o ka paʻakai wai, nāwaliwali kaʻakika, engine aila, gasoline, aromatic hydrocarbon pūhui a me nā mea hoʻoheheʻe maʻamau, inert i nā meaʻala, akā,ʻaʻole kū'ē i nāʻakika ikaika a me nā oxidants.Hiki iā ia ke pale aku i ka erosion o ka ʻaila, ka momona, ka waiʻona, ka alkali nāwaliwali, a me nā mea ʻē aʻe a loaʻa iā ia ka mana anti-kahiko.Hiki ke hoʻohana ʻia e like me ka hoʻopili ʻana i nā mea no ka lubricating aila, wahie, etc.

Nā hemahema:

1. Poor wai absorption a me dimensional paʻa.

2. Ke kū'ē maikaʻiʻole i ka mahana wela.

3. He ʻilihune ka waiwai antistatic.

4. ʻAʻohe wela wela.
