papa PPhe mea semi-crystalline. ʻOi aku ka paʻakikī a ʻoi aku ka nui o ka heheʻe ma mua o ka PE. Ma muli o ka palupalu loa o ka mahana homopolymer PP ma luna o 0C, nui nā mea pāʻoihana PP he copolymers maʻamau me ka 1 a i ka 4% ethylene a i ʻole nā copolymers clamp me nā mea ethylene kiʻekiʻe. ʻO ka liʻiliʻi, maʻalahi i ka weld a me ke kaʻina hana, me ke kūpaʻa kemika ʻoi aku ka maikaʻi, ka pale ʻana i ka wela a me ka pale ʻana i ka hopena, ʻaʻohe mea ʻawaʻawa a ʻono ʻole, ʻo ia kekahi o ka ʻenekinia PP plastics e hoʻokō i nā koi palekana kaiapuni. ʻO nā kala nui he keʻokeʻo, microcomputer kala, a me nā kala ʻē aʻe hiki ke hoʻopili ʻia e like me nā koi o ka mea kūʻai aku. Laulā noi: ʻakika a me nā mea hana pale alkali.

ʻO ka fiber glass fiber reinforced PP board (FRPP board): Ma hope o ka hoʻoikaika ʻia ʻana e 20% aniani fiber, ma kahi o ka mālama ʻana i ka hana maikaʻi loa, ua pālua ʻia ka ikaika a me ka rigidity i ka hoʻohālikelike ʻia me PP, a he maikaʻi ke kūpaʻa wela a me ka haʻahaʻa haʻahaʻa haʻahaʻa hopena, Anti-corrosion arc resistance, low shrinkage. Maikaʻi kūpono no ka fiber kemikal, chlor-alkali, petroleum, dyestuff, pesticide, meaʻai, lāʻau lapaʻau, ʻoihana māmā, metallurgy, sege treatment a me nā māla ʻē aʻe.

PPH papa, beta (β)-PPHʻaoʻao hoʻokahi papa ʻole i ulana ʻia. (β)-ʻO nā huahana PPH he maikaʻi loa ka wela a me ka oxygen aging resistance, lōʻihi ke ola o ka lawelawe a me nā waiwai mechanical maikaʻi. Ua hoʻohana maikaʻi ʻia i ka hana ʻana i nā papa, a ʻo ka ʻenehana kiʻekiʻe no ke kūlana alakaʻi ma Kina. Hiki ke hoʻohana ʻia kēia mau huahana no nā papa kānana a me nā ipu ʻeha spiral, no ka fiber glass i hoʻoikaika ʻia i nā papa wiliwili wiliwili, ka mālama ʻana i ka ʻoihana petrochemical, ka lawe ʻana a me nā ʻōnaehana anti-corrosion, nā mea kanu mana, nā lako wai, ka mālama wai a me nā ʻōnaehana wai no nā mea kanu wai; a me nā mea kanu kila, nā mea hoʻoheheʻe uila Wehe lepo, holoi a me nā ʻōnaehana ea, etc.
