Mid-Mountain Materials: Solving the World's Toughest Thermal Challenges

In the demanding world of industrial manufacturing, aerospace, and high-heat fabrication, the difference between operational success and catastrophic failure often comes down to the quality of a thermal barrier. Mid-Mountain Materials, Inc., a Seattle-based, ISO 9001:2015-certified manufacturer, has spent 40 years positioning itself as a global leader in the engineering of high-temperature-resistant materials.

As a prominent member of the Center for Advanced Manufacturing Puget Sound (CAMPS), Mid-Mountain exemplifies the innovation and leadership that drives our regional manufacturing sector. By combining vertical integration with a research-led approach, the company provides fast-to-market solutions that address the most critical challenges for modern industry.

Core Capabilities: A Multi-Disciplinary Approach to Heat

Mid-Mountain’s capabilities extend far beyond basic insulation. Their expertise lies in a diverse portfolio of high-performance materials designed to survive environments where traditional materials fail.

The Mid-Mountain Technical Toolkit:

• Coated Fabrics and Textiles: Featuring the ARMATEX® line (silicone, polyurethane, and refractory coatings) and SILTEX® woven silica textiles for welding and fire resistance.
• Fabricated Seals and Covers: The THERMOPAK® brand includes custom robot protective systems, tadpole gaskets, and stress-relieving blankets.
• Refractory Materials: The THERMOSEAL® line offers cements, coatings, and moldables formulated for high-strength sealing with minimal shrinkage during thermal cycling.
• High-Performance Fibers: The HYTEX® range uses advanced materials, including Kevlar®, Nomex®, and Carbon, to produce high-strength ropes, tapes, and sleeving.
• Thermal Insulation: CERMEX® mats and papers provide essential barriers for high-heat applications.

Solving the Problems of a Global Industry

Mid-Mountain Materials does not just sell products; they solve specific functional problems for engineers and plant managers.

1. Protecting Critical Assets in Extreme Environments

In weld cells and foundries, industrial robots operate where humans cannot safely work. Mid-Mountain’s THERMOPAK® covers shield motors and electronics from fire, spatter, and slag, ensuring automation remains online in the harshest fabrication lines.

2. Enhancing Efficiency and Sustainability

In the aerospace sector, the "job" is lightweighting. By using Neoprene Coated Fabrics, Mid-Mountain helps reduce aircraft mass, thereby improving fuel efficiency and lowering emissions. Their insulation barriers are also essential for energy conservation across varied industrial systems.

3. Ensuring Integrity in Hazardous Processes

The performance of an aluminum smelter depends heavily on the integrity of its sealing systems. Mid-Mountain provides the specialized seals required for reduction cells to convert alumina into molten aluminum safely and efficiently.

4. Mitigate Risk through Quality Assurance

High-stakes industries—from satellite manufacturing to emissions control—require total reliability. Mid-Mountain’s commitment to quality management, as evidenced by its ISO 9001:2015 certification, ensures that every product exceeds expectations for performance and service.
