FVMQ Fluorsilikon SD Gummi Hintergrund


high flexibility at extreme temperatures

Fluorsilicone rubber

Fluorosilicone (FVMQ) combines the high and low temperature properties of silicone with excellent

Resistance to many chemicals, as well as fuels and oils. This makes fluorosilicone particularly suitable

for applications in a wide temperature range and in contact with aggressive substances such as petrol or alcohol mixtures. Fluorosilicone is used in sealing technology, for example for O-rings, seals

and hose inner layers in automobiles as well as in aerospace engineering.


Chemical structure


Fluorosilicone rubber consists of a polymer chain in which silicon and oxygen atoms are bonded together. Fluorine atoms are bonded to these silicon atoms, and the polymer chain also contains organic groups,

especially methyl groups. This structure gives the fluorosilicone rubber its specific properties,

including improved chemical resistance due to the presence of fluorine atoms and flexibility

due to the organic methyl groups.


Material properties and resistance


  • excellent UV, ozone and weather resistance

  • temperature-independent flexibility and elasticity

  • Mainly used in the food and pharmaceutical industries, in the automotive sector, as well as in electrical and medical technology

  • very pure material, tasteless and odorless

  • special colouring according to RAL palette

  • Temperature resistance: -100°C to 320°C

The uniqueness of fluorosilicone compared to other rubber materials lies in its exceptional combination of temperature resistance, chemical resistance, flexibility and electrical insulation. These properties make fluorosilicone an indispensable material in demanding industrial environments where traditional rubber materials would reach their limits. flexibility Fluorosilicone exhibits high flexibility, making it ideal for applications requiring stretchability and bendability. Tear resistance It has excellent tear resistance, meaning it is resistant to mechanical stress. Wear resistance Due to its robust structure, fluorosilicone is very wear-resistant, which makes it ideal for use in demanding environments. density The material has a low density, resulting in lightweight end products. Insulation properties Fluorosilicone has good electrical insulation properties and is therefore used in the electrical and electronics industry. Weather resistance Fluorosilicone exhibits excellent resistance to weathering, making it suitable for outdoor use. Chemical resistance It is resistant to many chemical substances, including acids and bases, making fluorosilicone particularly desirable in the chemical industry. Temperature resistance Fluorosilicone maintains its material properties in extreme temperatures, both high and low temperatures. Not resistant to aromatic hydrocarbons and some strongly alkaline substances

Material hardness and coloring


Fluorosilicone is available in different degrees of hardness, from 40° to 80° Shore A. This variety allows it to be adapted to different application requirements. In addition, silicone can be produced specifically colored according to customer specifications, including black, green, white and blue, as well as in a transparent version.

Industries and applications


Fluorosilicone is primarily used in industries that require extreme conditions in terms of temperature, chemical resistance and flexibility. Its unique material properties

make it particularly indispensable in demanding industrial environments.

Aerospace The combination of temperature resistance, chemical resistance and flexibility makes fluorosilicone a preferred material for seals and O-rings in the aerospace industry.   Automotive Seals for engine components, fuel systems and various applications that require resistance to fuels.   Electrical Fluorosilicone's electrical insulating properties make it ideal for making cable insulation. It also provides protection from moisture and chemicals in electronic components.   Chemical industry Due to its outstanding resistance to various chemicals, fluorosilicone is used in the chemical industry for the production of seals and hoses where there is exposure to aggressive substances.   Medical and food industry Special seals and molded parts that are food-compliant and chemical-resistant.

The uniqueness of fluorosilicone compared to other rubber materials lies in its exceptional

Combination of extreme temperature resistance, chemical resistance, flexibility and electrical insulation.

These properties make fluorosilicone an indispensable material in demanding applications

industrial environments where all other rubber materials would reach their limits.
