Nā huahana

1. Hana maikaʻi haʻahaʻa wela;
2. ʻO ka oxygen maikaʻi a me ka pale ozone;
3. Machinability maikaʻi.(ka huli ʻana, wili, wili a me ka wili);
4. Loaʻa iā ia ka hana hoʻoheheʻe haʻalulu maikaʻi loa a hiki ke hoʻohana ʻia no ka hoʻemi haʻalulu a me ka cushioning.I loko o ka ʻoihana hana hoʻoheheʻe, hoʻololi i ka lāʻau a me ka puna;
5. E aahu i ka pale.ʻOi aku ka maikaʻi o kona pale ʻana, ma ka laulā o 0.01-0.10 (cm3) /1.61km, ma kahi o 3-5 mau manawa o ka lāʻau;
6. Ke kū'ē i ka radiation.He maikaʻi ke kū'ēʻana o ka polyurethane i ka pāhawewe ikehu kiʻekiʻe, a loaʻa naʻe ka maikaʻi o ka hana ma lalo o 10-10 Ge.
7. Laulā paʻakikī ākea.Loaʻa iā ia ka elongation a me ka resilience o ka lāʻau ma lalo o ka paʻakikī kiʻekiʻe.ʻO ka paʻakikī o ka polyurethane elastomer he kahakai a10-d80;
8. Paʻa ʻaila.ʻO ka polyurethane elastomer kahi ʻano o ka pūhui polar polymer ikaika, he liʻiliʻi ka pilina me ka ʻaila mineral non-polar a ʻaʻole hiki ke hoʻopau ʻia i ka ʻaila a me ka ʻaila mīkini.
9. Ka ikaika kiʻekiʻe.Ma lalo o ka paʻakikī o ka lāʻau lapaʻau, ʻoi aku ka kiʻekiʻe o ko lākou ikaika tensile a me ka hiki ke amo i ka ukana ma mua o ka ʻōpala maʻamau.Ma lalo o ka paʻakikī kiʻekiʻe, ʻoi aku ka kiʻekiʻe o kona ikaika hopena a me ka ikaika kulou ma mua o ka plastic.
