ʻO ka Polytetrafluoroethylene (PTFE) he polymer kaumaha molekala kiʻekiʻe, ʻo ia kekahi o nā mea palaki maʻalahi loa i ʻike ʻia a pono no ka nui o nā huahana no nā noi i kāpae ʻia i nā mea ʻē aʻe.
ʻO ka Polytetrafluoroethylene (PTFE no ka pōkole) he ʻōpala synthetic haʻahaʻa haʻahaʻa i hoʻohana lōʻihi ʻia no nā noi sealant no nā ʻano mea like ʻole me nā kinoea, nā wai, a me nā kemika.
PTFE O-Ring Temperature Range
ʻOiai he haʻahaʻa haʻahaʻa nā waiwai mechanical PTFE i hoʻohālikelike ʻia me nā plastics ʻē aʻe, ʻo ke kūpaʻa kemika o ka mea e like me kona hiki ke kū i kahi ākea ākea (-100oF a +400oF) e ʻae i nā apo o PTFE e hāʻawi i ke kūpaʻa maikaʻi i ka wā e like me ka uila a me ka wela. hoʻokaʻawale.
No ka mea, he ʻano mea paʻa ka PTFE, ʻaʻole hiki ke "hoʻoheheʻe ʻia" - pono e hoʻopili ʻia a hoʻopaʻa ʻia e hana i nā ʻano pono (e like me nā o-rings).
