Papa PPHe mea semi-crystalline. ʻOi aku ka paʻakikī a ʻoi aku ka kiʻekiʻe o ka hoʻoheheʻe ʻana ma mua o PE. No ka mea, he palupalu loa ka mahana o ka homopolymer PP ma luna o 0C, he nui nā mea PP kalepa he mau copolymers random me 1 a 4% ethylene a i ʻole nā ​​​​copolymers clamp me ka nui o ka ethylene. Liʻiliʻi, maʻalahi e hoʻopilikino a hana, me ke kūpaʻa kemika kiʻekiʻe, ke kūpaʻa wela a me ke kūpaʻa hopena, ʻaʻohe ʻawaʻawa a ʻono ʻole, ʻo ia kekahi o nā plastics PP ʻenekinia e hoʻokō ana i nā koi palekana kaiapuni. ʻO nā kala nui he keʻokeʻo, ke kala microcomputer, a hiki ke hoʻopilikino ʻia nā kala ʻē aʻe e like me nā koi o ka mea kūʻai aku. Ka laulā noi: nā lako hana kūpaʻa waikawa a me ka alkali.

Papa PP i hoʻoikaika ʻia me ke aniani fiber (papa FRPP): Ma hope o ka hoʻoikaika ʻia ʻana e 20% o ke aniani fiber, me ka mālama ʻana i ka hana maikaʻi loa mua, ua pāpālua ʻia ka ikaika a me ka paʻakikī i hoʻohālikelike ʻia me ka PP, a he kūpaʻa maikaʻi kona i ka wela a me ke kūpaʻa haʻahaʻa i ka hopena wela, ke kūpaʻa anti-corrosion arc, a me ka emi haʻahaʻa. He kūpono loa ia no nā kemika fiber, chlor-alkali, petroleum, dyestuff, pesticide, meaʻai, lāʻau lapaʻau, ʻoihana māmā, metallurgy, mālama wai ʻino a me nā ʻoihana ʻē aʻe.

Papa PPH, beta (β)-PPHpapa ulana ʻole ʻaoʻao hoʻokahi.β)-Loaʻa i nā huahana PPH ke kūpaʻa maikaʻi loa i ka wela a me ka ʻelemakule oxygen, ke ola lawelawe lōʻihi a me nā waiwai mechanical maikaʻi. Ua hoʻohana pono ʻia i ka hana ʻana o nā papa, a no Kina ka ʻenehana holomua i ke kūlana alakaʻi. Hiki ke hoʻohana ʻia kēia mau huahana no nā papa kānana a me nā ipu ʻeha wili, no nā papa uhi wili plastik i hoʻoikaika ʻia i ke aniani fiber, ka mālama ʻana i ka ʻoihana petrochemical, ka halihali a me nā ʻōnaehana anti-corrosion, nā mea kanu mana, ka lako wai, ka mālama wai a me nā ʻōnaehana hoʻokahe wai no nā mea kanu wai; a me nā mea kanu kila, nā mea kanu mana. Wehe lepo, holoi a me nā ʻōnaehana ea, a pēlā aku.
