Ko te rauemi rapa perfluoroether FFKM (Kalrez) te rauemi rapa pai rawa atu mō tete ātete pāmahana teitei, te ātete waikawa me te kawakore kaha, me te ātete whakarewa waroi roto i ngā rauemi hiri rapa katoa.

Ka taea e te rapa perfluoroether te ātete i te waikura mai i te neke atu i te 1,600 ngā whakarewa matū pēnei i tengā waikawa kaha, ngā kawakore kaha, ngā whakarewa waro, te mamaoa pāmahana tino teitei, ngā etera, ngā ketone, ngā mea whakamatao, ngā matū kei roto te hauota, ngā warowaihā, ngā waipiro, ngā aldehyde, ngā funan, ngā matū amino, me ētahi atu., ā, ka taea te tu atu i ngā pāmahana teitei tae atu ki te 320°C. Nā ēnei āhuatanga he otinga hiri tino pai i roto i ngā tono ahumahi e hiahiatia ana, inā koa i ngā āhuatanga e hiahiatia ana te pumau mō te wā roa me te pono teitei.

YāeKa whakamahia e te kamupene ngā rauemi mata rapa perfluoroether FFKM kawemai hei whakatutuki i ngā hiahia hiri motuhake a ngā kiritaki i raro i ngā tikanga mahi uaua. Nā te uaua o te tukanga hanga o te rapa perfluoroether, he torutoru noa iho ngā kaihanga o te ao e taea ana te whakaputa rauemi mata rapa perfluoroether.

Ko ngā tikanga tono noa mō ngā hiri rapa perfluoroether FFKM ko:

• Ahumahi hiko-haurua(te waikura plasma, te waikura hau, te waikura waikawa-pūtake, te waikura pāmahana teitei, ngā whakaritenga horoi teitei mō ngā hiri rapa)
• Ahumahi rongoā(te waikura waikawa waro, te waikura turanga waro, te waikura whakarewa waro, te waikura pāmahana teitei)
• Ahumahi matū(waikura waikawa kaha, waikura turanga kaha, waikura hau, waikura whakarewa waro, waikura pāmahana teitei)
• Ahumahi hinu(te waikura nui o te hinu, te waikura hauwai whanariki, te waikura whanariki nui, te waikura wāhanga waro, te waikura pāmahana teitei)
• Ahumahi motuka(te waikura hinu pāmahana teitei, te waikura pāmahana teitei)
• Ahumahi whakakikorua taiaho(kāore e taea e te waikura pāmahana teitei, te perfluororubber ma teitei te whakaputa i ngā katote konganuku)
• Ahumahi pākahiko(te waikura waikawa-pūtake, te waikura reo hohe kaha, te waikura reo whakahāora kaha, te waikura pāmahana teitei)

• Te umanga hiko karihi me te hiko wera(te waikura o te mamaoa pāmahana teitei, te waikura wai pāmahana tino teitei, te waikura irahiko karihi)
