evolast® FFKM – the ultimate generation of perfluoroelastomers
The development of FFKM has now raised rubber to a hitherto unknown peak in the sealing applications segment!
evolast® combines the excellent chemical and thermal properties of PTFE thermoplastics with the elasticity and superior compression set resistance of elastomers.

evolast® is used in the chemicals industry, in medicine and in food industry. It is also used in oil and gas production, and in processing all of the above products, as well as in many other applications where seals are expected to perform to highly exacting standards.
Until now, the high production costs of evolast® meant it could only be used in these areas. FFKM can provide significant benefits in applications where other elastomers or thermoplastics are used today.
The longer service life and cost savings that an extended service period offers often compensate for much more than just the high initial outlay.
Not least because of this is FFKM destined to make ever-increasing inroads into the sphere of technical applications, similar to how FKM did more than 40 years ago.
The O-rings made from evolast® FFKM range from small to large! Currently, some 10,000 different sizes are available from existing tools, the largest with diameters of up to 2000 mm. Also parts to customers specifications and drawings are being produced.
anyseals sees one of its tasks as supplying also evolast® O-rings in proven reliability from stock. Information on different compounds, as prices and delivery times, are available, as usual, from the anyseals e-shop.
