Custom Q&A

What are fluoroelastomers?

Fluoroelastomers are fluorinated synthetic polymers designed for harsh environments, including aggressive chemical and temperature applications.

What are the main factors that make fluoroelastomers a vital polymer?

The main factors that make fluoroelastomers a vital polymer are long term reliability and minimum change to the environment.

What are the temperature capabilities of fluoroelastomers?

Fluoroelastomers can withstand temperatures up to 204°C continuously and 300°C intermittently.

What are some of the resistance properties of fluoroelastomers?

Fluoroelastomers have great compression, sunlight, ozone resistance, and a low gas absorption rate.

What is the difference between FPM and FKM?

FPM is the international designation to ISO, while FKM is the ASTM abbreviation. Both designations stand for the same base material, which is fluoro rubber.

What are some of the benefits of using fluoroelastomers?

Some benefits of using fluoroelastomers include reducing the lifetime cost of ownership, stretching maintenance budgets for expensive plant and equipment, cutting unscheduled downtime, and ensuring compliance with tougher environmental regulations.

What types of oils and chemicals can fluoroelastomers resist?

Fluoroelastomers can resist aggressive oils and chemicals such as hydrocarbon fluids, amines, caustics, sulfur gases, mineral oils, and fats.

What are the three main factors that allow fluoroelastomers to have their unique quality?

The three main factors are extremely strong bonds between atoms, a high fluorine-to-hydrogen ratio, and a single carbon backbone.

Why are fluoroelastomers resistant to chemical attacks?

Fluoroelastomers are resistant to chemical attacks because the carbon atoms in their backbone are extremely resistant to change, they have a high fluorine-to-hydrogen ratio which makes them more stable, and their single carbon backbone is less likely to be affected by chemical attacks.

What are some of the petroleum products that fluoroelastomers have low permeation for?

Fluoroelastomers have low permeation for petroleum, oxygenate-rich fuels, and harsh engine oils.
