At NEDC, we have many materials to choose from when a customer discusses an application. For todays blog, I thought I’d write about an extreme material.
Why Choose Kalrez® Perfluoroelastomer?
The answer to this one is simple. If you have an application that requires a polymer rubber that is extremely resistant to:
What is the technical term for Kalrez®?
Kalrez is the brand name by DuPont known as a perfluoroelastomer.
Under ASTM D2000, Kalrez® is usually categorized as: ASTM D2000 KK
Kalrez® is a good option for environments where chemicals, and heat play a big role. Speaking of which, what counts as Extreme ?
Well Kalrez is Chemically Resistant to:
-Vegetable Oils/Fuel Oils/Lubricating Oils/Hydraulic Oils
In regards to temperature, and temperature cycling- it handles temperatures up to 525°F very well- and sometimes higher, along with cycling of temperature between 0°F and 525°F.
Naturally, there are different types of Kalrez® available. With some performing better than others in certain things. For example, Kalrez® 7075 has a much higher temperature resistance- all the way up to 620°F.
You may ask yourself, why theres just a label of the Kalrez® instead of an actual picture. My reason is, frankly its too expensive to waste. However, don’t get me wrong, Kalrez® provides every bit of value the cost suggests. If you are looking for something with high chemical resistance, and high temperature resistance, Kalrez® is a great choice.
Thicknesses range from .020’’ to .125’’ in thickness. Typical durometer availability for Kalrez® ranges from 65A to 95A durometer. NEDC die-cuts, and waterjet-cuts custom gaskets out of Kalrez® material from DuPont. This material comes in a plain black color like most rubbers. As with most materials NEDC supplies, we can supply it with an adhesive backing as well for ease during assembly. For more information on Kalrez® Perfluoroelastomer, please contact email@example.com.
