What is FFKM?
FFKM stands for perfluoroelastomers, which are a type of polymer that are highly chemically resistant and can withstand high temperatures.
What are the advantages of FFKM?
The advantages of FFKM include a wide temperature range, excellent chemical resistance, resistance to gas and liquid permeation, weather ability and ozone resistance, self-extinguishing and non-flammable properties, high density, and good mechanical properties for sealing performance. It is also suitable for explosive decompression, CIP, and SIP applications.
What are the disadvantages of FFKM?
FFKM can swell significantly in fluorinated solvents and should not be used with molten or gaseous alkali metals. It also has a thermal coefficient larger than other elastomers, which may require modification of seal housing size. Additionally, FFKM is generally higher in cost compared to other elastomers.
How is FFKM different from FKM?
FFKM offers a higher degree of versatility compared to FKM. It has greater chemical resistance and can withstand a wider range of operating temperatures, with peak service temperatures of up to 330°C. FKM, on the other hand, is a slightly lower cost option that still offers good chemical and temperature resistance.
Why is it important to seek the guidance of a technical expert when choosing an elastomer?
Choosing the correct elastomer for specific application requirements is important to prevent rapid failure and ensure proper performance. A technical expert can provide guidance and ensure the right elastomer is used.
In which industries is FFKM commonly used?
FFKM is commonly used in the aerospace and automotive industries, among others.
What are the temperature capabilities of FFKM?
FFKM has a temperature range of -55°C to 330°C.
What are the properties that make FFKM suitable for sealing applications?
FFKM has excellent chemical resistance, gas and liquid permeation resistance, and good mechanical properties, which make it suitable for sealing applications.
