Polypropylene CAS 9003-07-0
ʻO ka polypropylene ka mea maʻamau he semi aniani paʻa, ʻala ʻole, ʻono ʻole, ʻaʻohe mea ʻawaʻawa, me ka mānoanoa pili o 0.90-0.91, e hoʻolilo iā ia i ke ʻano māmā o ka plastic i ka hoʻohana maʻamau. Ma muli o kona ʻano hana maʻamau, he wahi heheʻe kona a hiki i ka 167 ℃ a ʻaʻohe wela. Hiki i kona hoʻohana mau ʻana i ka mahana ke hiki i 110-120 ℃, ʻaʻole ia e deform ma 150 ℃ ma lalo o ka ikaika o waho; ʻO ka pale ʻana i ka corrosion a me ka maikaʻi o ka hoʻokaʻawale uila.

Hiki ke hoʻohana ʻia ka polypropylene no ka hana ʻana i nā paipu wai anuanu a me ka wela a me nā mea pono no ka hoʻolako wai a me ka hoʻokahe. Loaʻa iā ia nā hiʻohiʻona o ka ikaika kiʻekiʻe, ke kūpaʻa creep maikaʻi, a me ke kūpaʻa maikaʻi loa i ka makū a me ka ʻelemakule wela. Hoʻohana ʻia ka polypropylene no nā ʻāpana hoʻonaninani e like me nā bumper kaʻa, nā panela mea kani, nā hale wela, nā ʻāpana anti friction, nā pahu pākaukau, a me nā pani puka.
Hoʻopili pinepine ʻia i ka 25kg / pahu, a hiki ke hana ʻia i ka pōʻai maʻamau.
