About this product

Brochure with technical information and basic knowledge on evolast® FFKM.

Angst+Pfister: One single partner integrating seamlessly compounding, engineering, production and distribution – And a 100 % European value chain.

evolast® FFKM is the next generation of perfluoroelastomer, combining the exceptional chemical and thermal resistance of PTFE with the elasticity and compression set resistance of elastomers. This translates to seals that can withstand extreme temperatures (up to +350 °C for premium grades) and a wider range of aggressive chemicals compared to other elastomers.

High thermal resistance – Wide temperature range from –46 °C up to +350 °C

A wide choice of components for static and dynamic sealing applications – Both in standard and customised geometries and dimensions

Heavy duty equipment in critical processes where mechanical seals, valves and pumps require the maximum performance in particularly harsh environments call for evolast® FFKM – The top choice for the most demanding applications in the Chemical Processing, Pharma, Semiconductor, Oil & Gas, and Aerospace industries.

Trusted by leaders in the Chemical Processing, Pharma, Semiconductor, Oil & Gas, and Aerospace industries

Regulatory compliance according to FDA, USP Class VI, EU 1935/2004, NORSOK, NACE, ISO 23936/2, API6A, and more

In the chemical process industry, where corrosive chemicals, high temperatures and challenging operating conditions are prevalent, the choice of materials for equipment components is critical. FFKM materials have emerged as indispensable solutions due to their exceptional resistance to a wide range of chemicals, including acids, bases, solvents, and aggressive fluids. evolast® FFKM can be versatile in the chemical process industry, from seals and gaskets to diaphragms and valve com

ponents. They are able to withstand harsh environments, ensure process integrity, and enhance equipment reliability and are the material of choice for demanding applications in the chemical process industry, contributing to safety, efficiency, and productivity in various chemical manufacturing processes.

• High Temperatures: Reactors, distillation, and cleaning processes often exceed +200 °C. • Frequent Cycling: Pressure and temperature cycling can lead to seal fatigue and leakage.

• Downtime Costs: Unscheduled maintenance due to seal failure is extremely costly.

Excellent choice for use in aggressive chemical environments, providing a broad chemical resistance to different media such as acids, bases, water, steam, amines, solvent based chemistries. It is recommended as a multipurpose compound in all applications where fluid handling of different substances is required due to its excellent chemical resistance to a wide range of chemicals. Ideal for valves, pumps, mechanical seals, sprayers, compressors, reactors. FDA tested according to 21 CFR 177.2600 e)-f) (migration test only), SGS test report 7926099.

For a wide operational temperature range without compromising chemical resistance in valves, pumps, mechanical seals, sprayers, compressors, reactors. Excellent choice for use in aggressive chemical environments, when thermal resistance is also required, exhibiting outstanding high temperature stability and low compression set.
