THERMOPAK® Tadpole Gasket Insulation
THERMOPAK® Tadpole Gasket is a high temperature insulation tape developed by combining a cover material with an inner core (bulb) material in a configuration most suitable for your application. Using a bulb and tail design, the tadpole gasket ensures optimum sealing performance and can be manufactured to address issues such as abrasion resistance, moisture resistance, and chemical resistance.

Our vertical integration gives us the opportunity to produce THERMOPAK® Tadpole Gasket from the materials that are best suited to your application. Cover materials for this insulation tape range from woven fiberglass or silica fabrics, to coated fabrics coated with silicone rubber or refractory coatings.

Core materials can include rubber materials such as neoprene or silicone for maximum density, or Inconel or stainless steel core for tadpole tapes that require more less density.

Typical sealing applications THERMOPAK® Tadpole Gasket insulation tape include oven and furnace doors, boilers, expansion joints, heat shield components, and ductwork. In addition to fabricated tadpole gaskets, Mid-Mountain offers HYTEX® Woven Tadpole Gaskets, manufactured from E-glass yarn and typically used for appliance sealing applications.

THERMOPAK® Fabricated Parts
THERMOPAK® Fabricated Parts are manufactured for use as thermal insulation barriers in applications that encounter high temperatures, emissions, chemical attack, and abrasion. The range of THERMOPAK® fabricated parts includes high temperature seals, and thermal insulation curtains and blankets.

We can manufacture these products to specific application requirements, ensuring the customer receives a fabricated part that is up to standard.

For over 40 years, Mid-Mountain has been manufacturing fabricated parts for a variety of industries, including automotive, aluminum, aerospace, transportation, petrochemical, welding, power generation, and many others.

Our vertical integration gives our customers the advantage of competitive pricing with shorter lead times and a higher level of quality control.
