FKM is a type of fluoroelastomer - a synthetic rubber - developed to withstand extreme conditions. The material is known for its high chemical resistance and temperature tolerance, making it ideal for applications in demanding industrial environments where standard materials are not sufficient.

FKM is resistant to high temperatures, acids, oils and chemicals. It is typically used in industries such as pharmaceutical, food and chemical industries where high demands are placed on material performance and durability. Compared to other rubber types, FKM offers superior chemical resistance and temperature tolerance, making it the preferred choice in many applications.

Features of FKM

• High temperature resistanceFKM can withstand temperatures up to 200°C, and briefly up to 275°C, making it suitable for applications with high operating temperatures.
• Chemical resistance: The material is resistant to a wide range of chemicals, including acids, oils and fuels, making it ideal for use in aggressive environments.
• Low gas permeabilityFKM has a low gas permeability, which is important in applications where tightness is crucial.
• Long lifespan: The material's resistance to heat and chemicals contributes to a long service life, even in demanding conditions.

However, it is worth noting that FKM has limited flexibility at low temperatures, which can be a disadvantage in certain applications.

Application areas for FKM

FKM is used in a number of industries, including:

• Pharmaceutical: For seals and gaskets in equipment with high demands on cleanliness and chemical resistance.
• Food industryIn food contact equipment, where the material must be approved for food contact and resist cleaning chemicals.
• Chemical industry: For hoses, gaskets and seals that need to withstand aggressive chemicals and high temperatures.

FAQ

What does FKM stand for?

FKM stands for fluoroelastomer and is a generic term for a group of synthetic rubber materials with high temperature and chemical resistance. The abbreviation FKM comes from the international ISO designation for this type of fluorine-based rubber. FKM rubber is often used in demanding industrial applications where regular rubber is not sufficient.
