What is Perfluoroelastomer FFKM?

What is Perfluoroelastomer FFKM?

Today we introduce two advanced elastomers engineered to withstand extremely high temperatures while meeting rigorous international standards for elastomeric material in oil and gas production.

The materials,  perfluoroelastomer FFKM is engineered to maintain excellent sealing function at very high temperatures while subjected to high pressure conditions. The materials, which combine these characteristics with excellent chemical compatibility.

Operators contending with extreme high temperatures, will now have the opportunity to reduce costs without the need to use higher cost solutions and pre-heated equipment.

Bestfluor 2675 operating temperatures range from -15°C to +260°C/-59°F to +500°F, while  Bestfluor 3075 operates from -15°C to +325°C/-59°F to +617°F These high Tg values allow the materials to remain elastic under pressure at much higher temperatures than standard grades.

The most widely spectrum of high-temperature grade chemical resistance, excellent acid resistance and amine resistance. It can be worked at reliably 300°C/572° and less hot water and steam environment for a long term.In examples where these high performance products have replaced the OEM fitted metal seals, uninterrupted production periods in excess of 10 years have been experienced without any lost production processes due to seal failures. Scheduled maintenance periods can also be safely extended leading to manpower savings coupled with increased production outputs.

FFKM is recognised as the market leading perfluoroelastomer which is resistant to over 1800 different chemicals while offering the high temperature stability of PTFE (327°C). The advanced properties of the product help maintain seal integrity with increased production safety, while also helping to minimise manufacturing and maintenance costs.

Typical worldwide markets that can benefit from the proven advantages offered by Kalrez products include aggressive chemical processing, food and pharmaceutical production activities, oil and gas recovery, petroleum applications, power generation together with semiconductor wafer processing involving a wide range of industrial and electronic grade chemicals.

Subsequent removal or in-situ repairs of affected equipment such as gear pumps, centrifuges, reactors and quick-release couplings can be expensive, particularly if the MTBF times are of short duration, leading to high unscheduled costing levels together with production shut-downs and process liquid losses. Labour costs alone covering major component strip-downs or complete unit replacements can be very substantial.
