Ua ʻike mākou a pau i ka piʻi ʻana o ka ʻili o ka polypropylene me ka piʻi ʻana o ka ʻike, a ʻoi aku ka maikaʻi o ka hopena anti-scratch, no laila hiki ke hoʻohana ʻia i nā manawa he nui, a ʻo ia nā mea maikaʻi e hiki ai ke lawe mai. I mea e hoʻomaikaʻi maikaʻi ai i kona rigidity ili a me ka maʻalahi, e hoʻohui mākou i nā mea polyethylene i ka papa polypropylene pp.
Ma hope o ka hoʻohui ʻia ʻana o ka papa PP i kūʻai ʻia ma ka mākeke me ka polyethylene e hana i ka polymer, hiki ke hoʻomaikaʻi wikiwiki ʻia i ka pale ʻana i ka wela, ka pale ʻana i ka corrosion, a me ka ikaika mechanical, no laila hiki iā ia ke lawe maoli i kahi hōʻoia maikaʻi. ʻOiaʻiʻo, pehea e hana ai i kahi koho maikaʻi loa he mea koʻikoʻi loa ia, a ʻo nā mea maikaʻi e hiki ai iā ia ke lawe mai e ʻoi aku ka koʻikoʻi, no laila e ʻoi aku ka maikaʻi o ka pale i loaʻa.
Ma ka ʻōlelo maʻamau, ʻoi aku ka maikaʻi o ka paʻakikī o ka ʻili a me ka pale ʻana o ka pepa PP, a ʻoi aku ka maikaʻi o ka hopena ma hope o ka hoʻohui ʻana i kekahi mau aniani aniani. Loaʻa nā ʻano like ʻole o nā ʻāpana polypropylene āpau o nā ʻano like ʻole, no laila hiki ke hoʻohana ʻia e like me kekahi o nā plastics ʻenekinia maikaʻi loa i kēlā me kēia manawa, e hāʻawi ana i ka hōʻoia hou aku no ka hana ʻana i nā lako like ʻole.
