Mid-Mountain Materials, Inc. is a global manufacturer of a range of thermal resistant materials for a range of different applications. We have a vast knowledge surrounding diverse material technologies and our engineering capabilities allow us to manufacture innovative solutions.
THERMOSEAL®
Our THERMOSEAL® range of refractory cements, moldables, and coatings are thermal resistant materials developed specifically for use in extremely high-temperature environments. The range is carefully engineered in order to withstand thermal contraction and expansion, they also benefit from the properties of very low shrinkage and high strength.
This range of thermal resistant materials is ideal for adhering gaskets and seals, as the heat-resistant properties ensure the seals are effective. They can also be formed into shapes and linings, or pushed into holes or cracks to provide protection against heat. Additionally, these products provide protection against molten metal corrosion, thermal spalling, and flame erosion.
Typical applications of the THERMOSEAL® range of refractory cements, moldables, and coatings include lightweight refractory linings, hearth products, induction furnace coil coatings, and trough coatings. This blog post will provide an insight into the THERMOSEAL® products we supply.
Thermal Cements
THERMOSEAL® Thermal Cements is a thermal resistant material that is designed to withstand thermal expansion and contraction under fluctuating heat conditions.
THERMOSEAL® 1000 and THERMOSEAL® 1000 SF cement are silicate pastes that have a maximum temperature resistance of 1000oF. They are cured in air in around 24 hours, removing the need for any expensive or difficult curing processes. Typical applications of these cements are to adhere metal to metal, firebox and brick repair (for THERMOSEAL® 1000) and adhering metal to fiberglass, and to fill stove and pipe cracks (THERMOSEAL® 1000 SF).
THERMOSEAL® 2000 is a thick cement that has a high use limit of 2000oF. This cement is particularly useful for placing gaskets and seals in furnaces, wood and coal stoves, and fireplaces.
Refractory Moldables
THERMOSEAL® Refractory Moldables are thermal resistant materials that are available in both low and high-density formulas. They can be spread into thin sections as surface coatings, formed into shapes, or pushed into cracks and holes.
THERMOSEAL® M22 is a pumpable sticky paste that can be formed into lightweight refractory shapes. It has a maximum use temperature of 2300oF. THERMOSEAL® M22 DRY MOLDABLE has a lot of the same features as M22, but it has a dry consistency and is mixed with water to create the required consistency.
THERMOSEAL® M33 has a use limit of 1830oF and it is resistant to molten metal alloy attack. This thermal resistant material has very low heat transfer and thermal conductivity, which makes it useful for coating, sealing, and patching in furnaces and troughs.
Non-wetting moldable, THERMOSEAL® M44 and M75 are comprised of bulk refractory fibers that form a non-sticky putty. Like M33, these moldables have a use limit of 1830oF, and they are ideal for use as a high-temperature filler and binder systems.
Thermal Coatings
THERMOSEAL® Thermal Coatings are often employed to provide protection against molten metal corrosion, flame erosion, and thermal spalling. They are applied easily by either spraying, dipping, or rolling to get a consistent finish over the entire surface.
THERMOSEAL® P110 and P120 are both white coatings that have use limits of 2300oF. P120 has a light paste consistency, while P110 is a thick paint, with a typical layer thickness of 2 mm.
P130 is a heavy green paste that also has a use limit of 2300pF, the typical layer thickness of this coating is 10 mm.
Another coating that has the consistency of a thick paint is P162. This thermal resistant material is black and has a lower use limit than the other coatings at just 500oF, which makes it suitable for applications when extremely high temperatures aren’t reached.
