Nā pōmaikaʻi o ka ʻeke kānana PPS:
1.PPS kānana eke he maikai thermal paʻa, thermal paʻa o instantaneous a me ka lōʻihi-manawa hoʻohana mau o nā mea a pau o kēia manawa 'enekinia kānana mea.
2. ʻO ke kūpaʻa corrosion maikaʻi.
3. Nā waiwai kino a me ka mechanical.ʻO ka ʻeke kānana PPS he wai maikaʻi a maʻalahi hoʻi e hoʻomaloʻo me ka fiber aniani, no laila maʻalahi ka hoʻopiha.Hoʻohana ʻia nā fibers aniani a i ʻole nā mea hoʻopiha inorganic o nā fibers aniani e hoʻomaikaʻi i ka ikaika tensile, ka pale ʻana i ka hopena, ka kuʻi ʻana a me ka elongation o ka ʻeke kānana PPS.
4. ʻO ka ʻeke kānana PPS he kūpaʻa maikaʻi ke kolo, haʻahaʻa haʻahaʻa o ka hoʻonui laina a me ke kūpaʻa maikaʻi.)
