Ko te polyurethane elastomer e piri ana ki te mata o te pahū he mea hangawai waerau hou i waenga i te rapa me te kirihou, he nui te kaha me te elasticity o te kirihou me te rapa.

Kei a ia nga ahuatanga e whai ake nei:

1.Wide awhe pakeke. Kei te roa tonu te roa me te kaha o te rapa i raro i te tino pakeke. Ko te awhe pakeke o te polyurethane elastomer ko Shore A10-D80.
2.High kaha. Ko to ratou kaha pakaru me te kaha kawe he nui ake i tera o te rapa o te ao i raro i te pakeke ano. I te tino pakeke, ko te kaha o te paanga me te kaha piko he teitei ake i te kirihou.
3. He tino pai te whakaahuru kakahu, i te nuinga o te waa 0.01-0.10 (cm3) /1.61km, mo te 3-5 nga wa o te rapa.
4.He pai te aukati hinu. Ko te polyurethane elastomer he ahua o te puhui polymer polar kaha, he iti te hononga ki te hinu kohuke kore-polar, a karekau e waikura ki te hinu hinu me te hinu miihini.
5. He pai te waikura me te ozone resistance.
6. He pai te mahi whakaurunga wiri, me te whakahekenga wiri, te paanga o te paatete.
7. He pai te mahi pāmahana iti.
