Ko te tikanga nairona pakeke tiketike, atu kākahu-ātete, arā i roto i te horopaki amo: kaha polyurethane ngawari ngā kino, engari pānga muffling e pai. O te akoranga, i reira ko te nairona ngohengohe, me polyurethane whai pakeke tiketike, a te tahi mau taime te rua taea tata pakeke (ngohengohe me te pakeke nairona polyurethane). I roto i rite poto ki te huru motuhake, he mea he pai pai. Kua tītaha ahau i roto i te manakohia o casters nairona, etahi o tona ake roa.

Polyurethane Ko te ripeka i waenganui i te kirihou me te rapa elastomer i waenganui i pai tona mahi whānui o te kirihou noa, me te rapa e kore e wātea ana. He āhuatanga hinu ātete pai, ātete ki te noho, radiation-ātete, kawenga nui, me te ru absorption moka me te rite.

Ngaiaku Ko te momo polyamide o kapia kirihou. Ko tōna kaha aunoa tiketike, taikaha pai, kurut tiketike, shock kaha. No te ru, wiri absorption kaha ahotea kaha, he nui ki runga ake i te kirihou toharite pānga kaha. Waikura resistance, a te nuinga o te otinga tote he kawakore, ano ātete ki te waikawa ngoikore, te hinu, penehīni, ātete ki whakarewa noa me pūhui kakara, i mangere pūhui kakara, engari e kore e ātete ki te waikawa kaha me te hāora. He whaiaro-whakanoatanga, kore-paitini, koreami, ātete weather pai, e mangere ki te whawhai koiora, he pai anti-kitakita, anti-pokepokea ai kaha.

wira Temperature polyurethane i -43 ~ 85 ° C, e tika ana wira pāmahana nairona i -43 ~ 126 ° C, te pāmahana tiketike ātete, kaha atu nairona wira polyurethane wira: tītaka wira polyurethane ngāwari wira nairona me te mahi ko rawa te pai; āhuatanga wahangu, wira polyurethane pai atu i te nairona wira: he pai atu polyurethane wira nairona wira te tiaki o te patunga witi; parewai, wira nairona wira polyurethane āhua rawakore; ki te ātete pānga me ngā āhuatanga abrasion pai ki wira polyurethane nairona wira: matū peehia, pai wira mahi polyurethane, nairona wira pai ana te whakahaere.
