PTFE/FEP vs Ultem® / PEI (polyetherimide) Mīkini

Ultem® / PEI (polyetherimide)he polymer amorphous ikaika loa me ka wela a me ka pale ʻana i ka lapalapa ahi (e lawe ana i ka helu flammability o 94-V-0) me ka liʻiliʻi o ka uahi.Hana mau ia i ka 340 ° F, e ʻoi aku ka maikaʻi ma mua o nā plastic commodity e like me Nylon a me Delrin®.

PTFEua hoʻomohala mua ʻia no ka hoʻohana ʻana i nā noi aerospace akā ua loaʻa koke kahi home i nā noi ʻoihana lehulehu.ʻO nā hiʻohiʻona kūʻokoʻa o PTFE he: kemika inertness (he kakaikahi loa nā kemika hiki ke hoʻouka iā ia), haʻahaʻa haʻahaʻa loa o ka friction (ʻaʻohe mea hiki ke hoʻopili i ka mea me ka ikaika), ke kūpaʻa wela kiʻekiʻe (hiki i nā mahana lawelawe o 500 ° F) a pono loa i nā kaiapuni mahana anu.

ʻO Ultem® / PEI (polyetherimide) he polymer amorphous ikaika loa me ka wela maikaʻi a me ka pale ahi (e lawe ana i ka helu flammability o 94-V-0) me ka liʻiliʻi o ka uahi.Hana mau ia i ka 340 ° F, e ʻoi aku ka maikaʻi ma mua o nā plastic commodity e like me Nylon a me Delrin®.ʻO Ultem® kahi hopena kūpono no nā noi e koi ana i ka ikaika kiʻekiʻe a me ka hiki ke kū i nā wela kiʻekiʻe.Ua kūpono ka huahana i nā noi e koi ana i nā waiwai dielectric maʻamau ma luna o kahi ākea o nā alapine.Hiki i ka Ultem® ke kūpaʻa i ka hydrolysis a kūpaʻa loa i nā hopena acidic a hiki iā ia ke ʻae i nā pōʻai autoclaving pinepine, e like me ka hoʻomaʻamaʻa mau ʻana o nā mea lapaʻau hiki ke hoʻohana hou ʻia.Hoʻohana nui ʻia ʻo Ultem® i ka uila ma muli o kona kūpaʻa arc maikaʻi a me ka mau dielectric.ʻO nā noi maʻamau ʻē aʻe e pili ana i nā mea hana analytical a me nā ʻāpana kūkulu e koi ai i ka ikaika kiʻekiʻe a me ka rigidity i nā wela kiʻekiʻe.
