Mid-Mountain Materials, Inc. specializes in the development of tailored insulation solutions for high-temperature applications. We engineer silicone-coated ropes using HYTEX® 1000 E-Glass yarns which boast a continuous upper use limit of 538°C (1000°F), and ample performance in short-term conditions of 815°C (1500°F). These are comprehensively resistant to compounds found in heat treatment applications and are impervious to various degradation phenomena such as rotting and thermal shrinkage. We elevate these properties with a functional coating of silicone rubber as required.

Silicone-coated rope is typically used as a sealing solution for high-temperature components with extremely tight tolerances regarding airflow and emissions. Natural gas and biomass furnaces often utilize silicone-coated rope as the primary seal for doors and apertures, given their combined flexibility and high abrasion-resistant capabilities. They can eliminate smoke emission when furnaces are closed and provide long-lasting performance through multiple use cycles.

Thicker silicone-coated ropes, such as square-braided components, are broadly used as sealants for electrolysis cells in primary aluminum manufacturing.

At Mid-Mountain Materials, Inc., we’ve positioned ourselves to weather these disruptions by embracing a business strategy centered on vertical integration. As a fully integrated company, we control every stage of the production process, from textile weaving to proprietary coatings and product fabrication. This structure offers not only greater control and cost savings, but also enables us to deliver a consistently high quality product to our customers—on time and at scale.

Our vertical integration gives us a competitive edge in both normal and disrupted market conditions. Here’s how:

• End-to-End Quality Control: From base fabrics to custom coatings and final assemblies, we monitor and test every element. This results in high quality, reliable products, even for mission-critical applications like thermal protection system (TPS) components and aircraft firewall insulation.
• Faster Lead Times: We avoid delays common to fragmented supply chains by owning our stages of production—from raw material preparation to final product delivery.
• Cost Savings and Reduced Costs: Internal production cuts out middlemen, reduces markups, and brings down unit costs over the long term, enabling us to offer cost-efficient solutions without compromising on quality.
• Product Customization: Because we manage each stage of production, we can create custom configurations of thermal insulation materials with specific temperature ranges, shapes, or certifications.
• Innovation Flexibility: Our R&D and fabrication teams work side by side, accelerating the development of novel materials and advanced solutions—like our flue insulation wrap jacket or engine blanket firewall systems.

Custom made for your application.

Mid-Mountain manufactures silicone-coated fabrics and textiles comprised of varying substrates coated with silicone rubber compounds. ARMATEX® Silicone Coated Fabrics and Textiles are engineered for use in environments that require high heat or flame resistance, chemical resistance, abrasion resistance, and UV or weather resistance.

Available in a wide variety of colors, our silicone-coated fabrics are developed to increase abrasion and chemical resistance to the substrate. Typical uses include removable pad insulation, protection from weld spatter and slag, gaskets, and thermal insulation barriers.
