Oven Gaskets

How They Keep Your Family Safe

Oven Gaskets

Oven gaskets are used to seal the oven door and keep the heat inside. In honor of Thanksgiving, we’re taking a look at how oven gaskets play a part in keeping your family safe this holiday as you’re spending the day in the kitchen.

The Importance of Oven Gaskets

Fiberglass rope is heat resistant and withstands high temperatures, so it is often the choice for oven gasket seals. If the gasket isn’t working properly, you might run into a couple of problems:

  • Your food will take longer to cook: Your oven will struggle to maintain the temperature required to cook your food, and the temperature will vary throughout the cooking process.
  • Your oven will use more energy: An oven gasket helps keep the heat inside so your oven doesn’t have to work as hard. Without the heat seal, your oven will have to use more energy to continue to maintain the temperature.
  • Heat will escape from the oven: This will create a dangerous environment in your kitchen, especially when cooking at a high temperature. Imagine walking by an oven that is letting out 450°F heat. Now, imagine what might happen if a child got too close.

Fiberglass on its own can withstand high temperatures. When coated with vermiculite—a hydrated magnesium aluminum sheet silicate mineral closely related to mica—it can withstand even higher temperatures. So, vermiculite is a top choice as a fiberglass coating for home ovens, commercial ovens, and microwaves.

Dicalite’s MicroLite Vermiculite Dispersions

MicroLite is produced by the chemical exfoliation of vermiculite. The vermiculite platelets that make MicroLite are inorganic, so MicroLite can be used as a high-temperature coating, binder, or filler in gaskets and for other products that are exposed to high heat. The addition of MicroLite imparts fire-resistance and upgrades the service temperature of the end product. Coatings of vermiculite on fiberglass textiles, like oven gaskets, have been shown to increase the service temperatures up to an impressive 1100°C.

Other MicroLite applications include:

  • Heat- and fire-resistant products like construction materials, specialty papers, and textiles
  • Fire-resistant fabrics
  • Barrier coating on films
  • Protective coating or sizing on glass fibers
  • High-temperature binder or barrier material
  • Coating for carbon/graphite materials to minimize oxidation
