Fluoroelastomers (FKM)...

Fluouroelastomers (FKM)...Clwyd has been at the forefront of fluoroelastomer compounding for over 20 years. We have a dedicated internal mixer for fluoroelastomer compounds which uses dry PEEK seals to eliminate oil contamination, and extensive use is made of 2-stage mixing to enhance compound consistency.  

Fluoroelastomers are often considered to be a single polymer type, but fluoroelastomers can be further subdivided on the basis of their monomer type(s). Different fluoroelastomer subtypes offer different compound properties (dependent on their constituent monomers and cure systems), which can lead to significant differences in compound performance. This large family of elastomers include polymers that are capable of resisting oils, methanol, caustic or corrosive chemicals, steam and extremes of temperatures (as low as -50°C or as high as 320°C). As fluoroelastomer specialists, we can help guide you to the most suitable fluoroelastomer subtype for your needs.

You can find more information on properties of the various types of fluoroelastomers available by looking at the polymer profiles listed below, or to compare the properties of the different grades use our FKM selector tool. Alternatively, our technical support team will be able to assist you in selecting the right compound for your application.
