He mea semi-crystalline ka pepa PP. ʻOi aku ka paʻakikī a ʻoi aku ka kiʻekiʻe o ka hoʻoheheʻe ʻana ma mua o ka PE. No ka mea, he palupalu loa ka mahana 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.

He haʻahaʻa ka mānoanoa o ka pepa PP maʻemaʻe, maʻalahi ke hoʻoheheʻe a hana ʻia, loaʻa iā ia ke kūpaʻa kemika kiʻekiʻe, kūpaʻa wela a me ke kūpaʻa hopena, ʻaʻohe ʻawaʻawa a ʻono ʻole, a ʻo ia kekahi o nā plastics ʻenekinia aloha honua loa. ʻO nā kala nui he keʻokeʻo, kala microcomputer, a hiki ke hoʻopilikino ʻia nā kala ʻē aʻe e like me nā koi o ka mea kūʻai aku. Nā noi: nā lako hana kūpaʻa waikawa a me ka alkali, nā mea hana pepa pp.

ʻO ka pepa extruded Polypropylene (PP) kahi pepa plastik i hana ʻia ma ka hoʻohui ʻana i nā mea hoʻohui hana like ʻole i ka resin PP ma o ka extrusion, calendering, cooling, cutting and other extrusions.

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

Ua hoʻohana pono ʻia ka pepa PPH i ka hana ʻana o nā pepa, a ʻo ka ʻenehana holomua ke kūlana alakaʻi ma Kina. Hiki ke hoʻohana ʻia kēia mau huahana no nā papa kānana a me nā ipu ʻeha wili, no nā pepa uhi wili plastik i hoʻoikaika ʻia me 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: ka wehe ʻana i ka lepo, ka holoi ʻana a me nā ʻōnaehana ea, a pēlā aku.
