If you work with applications that see high or extreme temperatures, chances are, you probably need an insulative gasket somewhere in the application. Whether this is something that you have actively thought about or not, we’re here to give you the rundown about insulative gaskets and the materials they are made from.

Before we get going, we thought it would be interesting to get your thoughts on insulative gasket materials.

Why Do I Need One?

thermosToday’s engines are burning hotter than ever. With the increased temperatures, it is becoming more common to have components that must be protected from the heat. A lot of times, an easy and inexpensive way to do this is with your gasket. An insulative gasket will insulate the heat on one side of the flange, keeping the heat away from these sensitive components. You already need to invest in a gasket, and depending on the material chosen, you may also be forced to invest in a heat shield. If you make the right material selection and combine the two, you can kill two birds with one stone.

Your engine can get even hotter due to heat soak. When the engine is off, you can’t rely on the cooling systems to protect the components. Don’t fret…some gasket materials are even known for their ability to move the heat, which results in a cooling effect.

What Gasket Material Should I Select?

Let’s say that you need an insulative gasket. What material should it be made out of? There are a lot of gasket technologies out there. Which one works the best?

First, with high-temperature applications, you really have two options. If we’re talking about surviving heat in general (insulation not needed), most people will select either a metal-reinforced composite laminate or embossed stainless steel (MLS/SLS). With the proper material selection, both have comparable performance levels. When you start getting more into the extreme heat (in excess of 800°F), you’ll find that you need to move more into the composites.

However, if you need an insulative gasket, your ONLY option is a metal-reinforced composite laminate, no matter what the temperature. This material is the only one with insulative properties and steel reinforcement, and the only one that can be constructed to specifically meet the needs of a particular application (if the need arises). Stainless steel shims heat up right along with everything else in the engine and won’t insulate. Composites with graphite, vermiculite, mica, and certain types of fibers are necessary to provide some heat management.

Finding the Right Composite

Talk to your trusted gasket material supplier if you are in need of an insulative gasket. Based on the requirements and the environment it will need to survive in, they should be able to give you a few options. If they can’t, keep looking until you find someone who can.

Thinking of Using a Gasket To Insulate Against Heat? Here Are 4 Considerations.
Gasket materials that have insulative properties can be a perfect fit for your application in so many ways. Keep reading for a list of considerations if you are trying to decide if this would be the answer to your problem.
3 Reasons Why You May Want to Utilize an Insulating Gasket
Sometimes a gasket needs to be more than just a gasket. There are times you may find that you are in need of an insulating gasket. There are also times that you could use an insulating gasket and don’t even realize it. If you’re not quite sure what you need, continue reading to learn about a few instances when an insulating gasket may be a benefit to your application.
What Qualifies as 'High Temperature' When Talking About Gaskets?
If you ask half a dozen application engineers and gasket fabricators what they consider to be ‘high temperature’ in regards to their selection of a gasket material, you’re likely to get a range of answers. You’ll also find that none of them are really wrong, since ‘high temperature’ is a relative term. So, how does one navigate the world of high temperature gasket materials when the terminology is so ambiguous?
The Top 6 Applications Where Composite Gaskets Excel
There are a handful of gasket materials and technologies that are acceptable for a variety of conditions within an application. However, as you venture into specific conditions, those options start to narrow – especially as you get into higher temperature and higher pressure applications.
4 Things to Know About Heat Shields & Thermal Management
Heat has always been an issue in and around engines. Over the last few years, heat has increased significantly in these areas such that engineering teams need to include provisions for thermal management in their designs. If you’re still learning more about this technology, we invite you to continue reading.
What's So Special About Gasket Material for Exhaust?
Hot, Hot, HOT!! If you’re well versed in combustion engines, you likely associate exhaust systems with extreme heat. If you aren’t sure about what to look for in an exhaust gasket material, read on to learn how to identify a material that will survive in the exhaust environment.
Uneven Temperature Exposure – Is There A Solution?
We have recently been looking at applications that have uneven temperature exposure around the perimeter of gaskets. In some cases, one side sees more heat than the other. From the material manufacturing side, there are a number of things we can do...
