ʻO ka mea laholio perfluoroether FFKM (Kalrez) ka mea laholio maikaʻi loa ma ke ʻano oke kūpaʻa wela kiʻekiʻe, ke kūpaʻa ikaika o ka waikawa a me ka alkali, a me ke kūpaʻa o ka mea hoʻoheheʻe organikma waena o nā mea sila elastic āpau.

Hiki i ka ʻūpā Perfluoroether ke pale aku i ka pala mai nā mea hoʻoheheʻe kemika he 1,600 a ʻoi aku e like menā waikawa ikaika, nā alkalis ikaika, nā mea hoʻoheheʻe organik, ka mahu wela kiʻekiʻe loa, nā ethers, nā ketones, nā coolants, nā hui i loaʻa ka nitrogen, nā hydrocarbons, nā alcohols, nā aldehydes, nā funans, nā hui amino, a pēlā aku., a hiki ke kū i nā mahana kiʻekiʻe a hiki i ka 320°C. ʻO kēia mau ʻano e lilo ia i mea hoʻonā sila kūpono i nā noi ʻoihana koi nui, ʻoiai i nā kūlana kahi e pono ai ke kūpaʻa lōʻihi a me ka hilinaʻi kiʻekiʻe.

YʻaeHoʻohana ka ʻoihana i nā mea maka perfluoroether FFKM rubber i lawe ʻia mai e hoʻokō i nā pono sila kūikawā o nā mea kūʻai aku ma lalo o nā kūlana hana paʻakikī. Ma muli o ke kaʻina hana paʻakikī o ka perfluoroether rubber, he kakaikahi wale nō nā mea hana ma ka honua i kēia manawa e hiki ke hana i nā mea maka perfluoroether rubber.

ʻO nā kūlana noi maʻamau o nā sila laholio perfluoroether FFKM:

• ʻOihana semiconductor(ka pala plasma, ka pala kinoea, ka pala waikawa-kumu, ka pala wela kiʻekiʻe, nā koi hoʻomaʻemaʻe kiʻekiʻe no nā sila laholio)
• ʻOihana lāʻau lapaʻau(ka pala ʻakika organik, ka pala kumu organik, ka pala hoʻoheheʻe organik, ka pala wela kiʻekiʻe)
• ʻOihana kemika(ka pala ikaika o ka waikawa, ka pala ikaika o ke kumu, ka pala kinoea, ka pala o ka mea hoʻoheheʻe organik, ka pala wela kiʻekiʻe)
• ʻOihana ʻaila(ka pala ʻaila kaumaha, ka pala hydrogen sulfide, ka pala sulfide kiʻekiʻe, ka pala ʻāpana organik, ka pala wela kiʻekiʻe)
• ʻOihana kaʻa(ka pala o ka ʻaila wela kiʻekiʻe, ka pala o ka wela kiʻekiʻe)
• ʻOihana electroplating laser(ʻo ka pala wela kiʻekiʻe, ʻaʻole hiki i ka perfluororubber maʻemaʻe kiʻekiʻe ke hoʻoulu i nā ion metala)
• ʻOihana pila(ka pala ʻakika-kumu, ka pala ikaika o ka waena hana, ka pala ikaika o ka waena oxidizing, ka pala wela kiʻekiʻe)

• ʻOihana mana nuklea a me ka mana wela(ka pala o ka mahu wela kiʻekiʻe, ka pala o ka wai wela kiʻekiʻe loa, ka pala o ka radiation nukelea)
