Have you ever been in a situation where you are working in a high-heat application and you need to figure out a way to insulate against the heat? One option is to look at some heat shielding. A shield can be designed to fit exactly where you need it to go, and away you go. Another option is to put your gasket to work. This is a viable option if you don’t have the space or the need for an actual heat shield.
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.
So You Think You Want To Insulate With a Gasket?
Whether you have heard of using a gasket for insulation purposes or not, here are 4 things you need to consider.
1. Do you need protection?
You may have a sensitive component, such as an actuator, on one side of the gasket that needs protection from the hot flange on the other side.
2. Does your application have a lot of heat soak?
Cooling systems work fine, but once the engine is off, it’s off to the races with heat soak, where cooled components can heat up. Once the cooling system is no longer running, nothing is regulating the temperatures, which over time, can cause damage in the application. It is important to identify the proper materials in the designs to tolerate the increased temperature conditions that may occur in some circumstances.
3. Do you plan to use a metal gasket?
These have successfully sealed many newer engines, but also transfer heat from one area to another, effectively making areas hotter. If you want to use a gasket for insulation, you’ll need to stay away from metal. The best gasket materials to use for an insulative effect are metal-reinforced composite laminates.
Sometimes a heat shield and gasket can be one in the same, thus reducing cost and installation issues. (For example, our HT 337 can function as both the gasket and heat shield when formed to do so – and it is quite successful in the applications!)
Over the years, we have recommended materials to many of our customers that are looking for insulative properties in their gaskets, and they have had much success with it. If you are in a similar situation, talk to a trusted gasket material supplier to see if what they have to offer will meet your requirements. If not, find someone who does, because it can be done.
Sometimes, insulation is just as important as any other material property! If you are interested in subscribing to Sealed-In’s blog posts, email firstname.lastname@example.org.
3 Reasons Why It May Matter Which Side of the Gasket Is Up
If a tree falls in the forest and no one is there to hear it, does it make a sound? Which came first, the chicken or the egg? Which side of a gasket needs to face up? Ok, maybe a gasket having sides isn’t one of the great hypothetical questions of our time, but have you ever really thought about it? Believe it or not, there are instances where it matters. Whether you have spent any time debating this with others or not, here are a few things that you need to know.
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. In comparison to many other technologies, heat shields are a relatively new concept. They have begun to be used regularly over the last few years, but are still new enough to not yet be the norm for everyone. If you’re still learning more about this technology, we invite you to continue reading.
What Is A Metal-Reinforced Gasket and Why Do I Need One?
If you were in the market for a gasket, do you even know where to start? As you can see, we’ve broken down why you want to consider a composite material. Now, the big question for some of our readers may be: “What exactly is a composite gasket”? For starters, the terms ‘metal-reinforced gasket’ and ‘composite gasket’ are...
Why A Metal-Reinforced Gasket May Not Be For You
We’re going to shoot you straight…you may never be in need of a metal-reinforced gasket. There. We said it. You could call us up tomorrow and ask for gasket material for XYZ application, and after telling us about your needs, we’d tell you that you would be better off spending your money elsewhere. You might be asking yourself “what kind of sales pitch is that”? Well, it’s an honest one.
Metal Tech Industries has many years of experience working in high temperature applications. Our gasket materials withstand high temps and the rigors or sealing joints in exhaust systems. With that background, a natural progression is heat shielding and thermal management.
