How to Simply Seal the Door of an Industrial Oven with a Tadpole Tape Gasket ? By: Jocelyn Vachon VP Innovation Group - Robco There are a variety of types of industrial ovens with various door geometries. To seal the heat (radiation, convection, conduction) inside the oven, a flexible gasket is often required. Some ovens incorporate a groove to place an insulating rope. Also, strips or extrusions made of polymers from silicone or fluorocarbon can operate at relatively high temperatures. The most viable option, however, is a tadpole tape gasket. But, what is a tadpole tape gasket? What are the materials used ? A tadpole tape gasket consists of mineral-based textile materials (fiberglass, silica, ceramic) made into a seal starting with a core made of an insulating rope, surrounded by a sown fabric, the ends of which are allowed to extend (see graphic). A wire mesh can be added to the surface, to protect the fabric from excessive wear. Alternatively, a core of knitted metal wi...
