PEEKhe thermoplastic i hana maikaʻi ʻia ma lalo o ka ʻike ʻana i nā wela kiʻekiʻe a me nā wahi kemika.ʻO ka hiki i kēia mea ke mālama i kona mau waiwai kino a kū i nā mahana a hiki i 480 degere F he mea waiwai nui ia i kūpono no nā ʻano hoʻohana like ʻole me ka pani ʻana i ke kila kila ma nā wahi paʻakikī.He ʻano māmā ia i ke kila a me ka alumini a me ke kūpaʻa lole kiʻekiʻe me ka ʻole o ka lubrication.
ʻO ka polyethylene kaumaha kiʻekiʻe-molecular-kaumaha (UHMWPE, UHMW) he ʻāpana o ka polyethylene thermoplastic.ʻIke pū ʻia ʻo high-modulus polyethylene, (HMPE), a i ʻole polyethylene hana kiʻekiʻe (HPPE), he mau kaulahao lōʻihi loa kona, me ka nui o ka molekala ma waena o 3.5 a me 7.5 miliona.ʻO ke kaulahao lōʻihi ka hoʻoili ʻana i ka ukana i ka iwi kuamoʻo polymer ma o ka hoʻoikaika ʻana i nā pilina intermolecular.Loaʻa kēia i kahi mea paʻakikī loa, me ka ikaika hopena kiʻekiʻe loa o kekahi thermoplastic i hana ʻia i kēia manawa.
