Have you ever been doing research on a product and instead of being forced to read through a lot of mumbo-jumbo, you just want a nice eye chart with a little bit of explanation around it? Well, if you’re researching gasket materials and specifically want to see the differences between vermiculite and graphite, you’re in luck!
Each of these materials can hold its own, but they do have their specific strengths. Depending on your application, either vermiculite or graphite is going to be your best bet. Which one are you willing to put your money on?
What’s the Difference?
Vermiculite vs. Graphite Showdown
|Capable of exhaust gasket services||Both vermiculite and graphite|
|Better oxidation resistance and surviving high temperatures||Vermiculite only|
|Better sealability||Graphite only|
|Available in various thicknesses||Both vermiculite and graphite|
|Incorporated into fiber matrix for durability||Vermiculite only|
|Improved performance when supported with metal core||Both vermiculite and graphite|
|Capable of sealing fluids||Graphite only|
|Mined out of the earth||Both vermiculite and graphite|
In general, when you are working with exhaust applications with high temps and signs of oxidation, you will want to look at a vermiculite product because it will resist oxidation more than graphite. If you are working with exhaust applications where sealabilty is critical and temperatures are not extreme, the graphites are going to meet your needs. If temperatures prove to be too much for the graphite, a vermiculite-based product is your next step.
