Polypropylene CAS 9003-07-0
ʻO ka Polypropylene he mea paʻa hapalua moakaka, ʻala ʻole, ʻono ʻole, ʻaʻohe mea ʻawahia, me ka nui o 0.90-0.91, ʻo ia ke ʻano māmā loa o ka plastic i ka hoʻohana maʻamau. Ma muli o kona ʻano maʻamau, he kiko heheʻe kona a hiki i ka 167 ℃ a he kūpaʻa i ka wela. Hiki i kona mahana hoʻohana mau ke piʻi i 110-120 ℃, a ʻaʻole ia e hoʻololi i ke ʻano ma 150 ℃ ma lalo o ka ikaika o waho; Kūʻē i ka palaho a me ka hana insulation uila maikaʻi.

Hiki ke hoʻohana ʻia ka Polypropylene no ka hana ʻana i nā paipu wai anuanu a me ka wai wela a me nā mea hoʻopili no ka hoʻolako wai a me ka hoʻokahe wai. Loaʻa iā ia nā ʻano o ka ikaika kiʻekiʻe, ke kūpaʻa maikaʻi o ka kolo ʻana, 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 bumpers kaʻa, nā panela mea kani, nā hale hoʻomehana, nā ʻāpana anti friction, nā hihia pila, a me nā panela puka.
Hoʻopili pinepine ʻia i loko o 25kg / pahu, a hiki ke hana ʻia kahi pūʻolo i hoʻopilikino ʻia.
