FFKM, or perfluoroelastomer, contains higher amounts of fluorine
than standard FKM, and features higher temperature ratings, up to approximately
330°C. FFKM also has improved chemical resistance, with nearly universal chemical
compatibility.
No people are often mistaken with this we would like to inform
you that ffkm is the main elastomer whereas kalrez is a brand of dupont of ffkm
rubber similarly is chemraz these are brands of ffkm elastromer and not a different
elastomer altogether.
Well lets say FFKM is a package that no other rubber can provides
because its resistant to universal chemicals offers high and low temperature
resistance, its durable and products can be obtained in customized sizes and shapes
and applications, but again this comes at a price that’s why ffkm is expensive than
all the other elastomers.
Yes ffkm withstands upto 330 c and is resistant to almost all the
universally accepted chemicals.
