Perfluoroelastomer FFKM O-rings

Over 5000+ different sizes of Perfluoroelastomer FFKM O-rings we can make. And any shapes or size we can do according to custom need.


Perfluoroelastomer FFKM O-rings - Sunraz™

Sunraz™ Perfluoroelastomer FFKM o-rings are the best high-performance group of rubber o-rings together with the maximum temperatures (up to 330°C) as well as best chemical resistance. FFKM o-rings are specifically created for extraordinary purposes where up time efficiency is worth the significantly higher cost in comparison with additional standard rubber products.

We can easily produce and also deliver perfluoroelastomer FFKM o-rings, seals, and gaskets developed from several different FFKM components. We can offer FFKM o-rings in conventional shapes in addition to seals and also gaskets in unique styles to fit your special features.

Perfluoroelastomer FFKM o-rings are usually suitable for their wide temp range, chemical level of resistance in numerous ruthless programs, and extended services life. A series of Sunraz™ FFKM O-Rings is invented by us Ningbo Sunshine in order to support our customer can easily switch from earlier suppliers in order to save their cost a lot. Clients who applied Kalrez®, Chemraz®, and PERFREZ® solutions before can also obtain their counterparts in our product checklist. We certainly have chemical resistance compound FFKM O-rings series and high temperature resistance compound FFKM O-rings range, and also high purity FFKM series. Personalized compound design and style is accepted by request. We offer common FFKM O-rings in AS-568, JIS B2401, JIS P, JIS V, JIS G, JIS S and global metric.

Perfluoroelastomer FFKM O-rings

The 3 Well-known Brand names of FFKM Perfluoroelastomer in the World.

DuPont™ Kalrez®

DuPont™ Kalrez® FFKM O-rings, seals, and gaskets constructed from DuPont™ can resist over 1,800 unique chemicals as well as offer high temperature firmness similar to PTFE, temperature as much as 327°C. Kalrez® FFKM is well-suited to utilize in the handling of highly intense chemicals, semiconductor wafer fabrication, drug refinement, oil and natural gas recovery, and also aerospace programs.
Kalrez® o-rings, gaskets, and seals give demonstrated, long-term overall performance, this means a smaller amount frequent replacement, repair, and examination and greater operation as well as equipment uptime for increased production and overall yield.

By decreasing particulates, cutting down extractables, and also resisting degradation in severe plasma circumstances, Kalrez® FFKM o-rings also aid prevent pollution in semiconductor handling. This material also delivers low outgassing in vacuum-sealing applications.


Chemraz® FFKM provides excellent level of resistance to heat and also most chemicals and solvents. Its greatest advantages, nonetheless, possibly its amount of resistance to steam and also significantly advanced low-temperature properties. The principle monomer of Chemraz® is tetrafluoroethylene (TFE), though its subsequent and third perfluorinated monomers are exclusive to the materials, and also provide the balance of its helpful features.

Chemraz® FFKM is the most powerful elastomer designed for challenging oilfield purposes. It gives you superb sealing effectiveness when subjected to mixes of extreme downhole chemical substances, as well as is often given by operators. Specially-formulated materials can give enhanced resistance to fast gas decompression and abrasion, in so doing minimizing down time for routine maintenance necessities.


Tecnoflon® PFR FFKM perfluoroelastomer o-rings offer the greatest quantities of performance of all FFKM elastomers. This material is proof against nearly every class of chemicals, as well as some grades can refrain from temperature conditions over 572°F/300°C, making Tecnoflon® PRF FFKM the best choice for requiring sealing applications.

And other FFKM rubber compounds such as Perlast® FFKM, Isolast® FFKM, Parofluor® FFKM also famous in markets. And our Sunraz™ can replace them in a cheaper cost.

China FFKM O-rings

What is FFKM and FFKM Same As Kalrez®?

Via the 1960s, there had been a growing desire for a polymer that was in fact far more chemically protected as well as had higher temp capabilities. Perfluoroelastomers ended up the natural conclusions, combining the chemical substance amount of resistance of PTFE with the versatility as well as resilience of normal FKMs. Originally, this next phase of elastomer technologies was almost exclusively the preserve of space programs and chemical operations. Nevertheless, FFKM had been soon appreciated by the wider manufacturing community, the moment its valuable properties became well-known.

FFKM, or perfluoroelastomer, contains higher amounts of fluorine than standard FKM, and features higher temperature ratings, up to approximately 325°C. FFKM also has improved chemical resistance, with nearly universal chemical compatibility

Perfluoroelastomers FFKM are best known as DuPont™ Kalrez, although other grades do exist. The compounds contain fully fluorinated polymer chains and hence offer the ultimate performance of elastomers when considering heat and chemical resistance.
