Yakanyanya Chemical Resistance: FFKM O-mhete inopokana neyakasiyana siyana yemakemikari, zvinonyungudutsa, acids, uye zvimwe zvinokuvadza zvinhu, zvichiita kuti zvive zvakakodzera kushandiswa mukuda makemikari ekugadzirisa zvikumbiro.
High Temperature Resistance: FFKM O-mhete inogona kumira kutonhora kwepamusoro kusvika ku600 ° F (316 ° C) pasina kuputsa, uye mune dzimwe nguva, kusvika ku750 ° F (398 ° C).
