FKM Compounds

Fluoroelastomers (FKM) are high-performance materials designed to withstand the most extreme conditions. FKM-based compounds are widely used in industries where reliability, sealing, and chemical and thermal resistance are critical.

On this page, we explore the key characteristics, applications, and benefits of FKM compounds, with helpful links for in-depth technical specifications.

Main Applications of Fluoroelastomer Compounds

Fluororubber compounds are used in highly specialized applications, particularly in the following sectors:

Automotive: gaskets, O-rings, and components subjected to high temperatures and aggressive fuels.
Chemical and petrochemical industries: static and dynamic seals in contact with solvents, acids, and strong bases.
Aerospace: critical components requiring thermal resistance and dimensional stability.
Food industries (in certified variants): gaskets for CIP/SIP systems.
Oil & Gas: special compounds resistant to H₂S, methane, and drilling fluids.
Electronics and sensors: insulation and protection in corrosive environments.

FKM Material

The term FKM identifies a broad family of synthetic fluoroelastomers, characterized by a high percentage of fluorine in their chemical structure. This provides:

Excellent chemical resistance to fuels, oils, acids, and aggressive solvents
Thermal stability at high temperatures
Low gas permeability
Good long-term elasticity
Excellent resistance to atmospheric agents, ozone, and UV rays
Extended durability even in harsh environments

Compounds can be formulated with different polymers (copolymers, terpolymers, bisphenol- and peroxide-cured) based on application needs.

Fluoroelastomer Operating Temperature

FKM compounds are designed to operate over a wide temperature range, generally between -20°C and +230°C, with higher temperatures in special compounds. The choice of formulation is crucial to ensuring performance and safety.

Chemical Resistance of Fluorocarbon Rubber

One of the key characteristics of FKM compounds is their high chemical resistance, making them suitable for fluids.
