The Mid-Mountain Materials, Inc. Company Overview Video details the transition of our company from its early start in a garage to manufacturing environmental protection products and thermal barriers for companies around the world to preserve our climate and planet.

Donald Knapp, founder of Mid-Mountain, began constructing asbestos replacement seals in his garage in 1967. As the demand for asbestos replacement products grew, so did the product line, and Mid-Mountain was incorporated in 1976. Currently our manufacturing resides in a 60,000 sq ft building in Arlington, Washington, with the Corporate Office located in Seattle.

Mid-Mountain began serving primary industries in the Northwest such as ferrous and non-ferrous metals, steel, aluminum and foundries with high-temperature, abrasion and chemical resistant products. Since that time Mid-Mountain has expanded into other markets such as marine response, transportation, automotive, hearth products, defense, renewable energy and robotics, along with many others. Research and development is at the core of what we do, and you will see in our video how our products evolve from an idea to conception.

Mid-Mountain Materials, Inc. is unique in that we are very vertically integrated company with four manufacturing divisions under one roof:

  • Textiles knitting, braiding and weaving (using various high-temperature and high strength substrates)
  • Coated fabrics and textiles (using various compounds such as silicone, hypalon, neoprene and polyurethane)
  • Fabrication (welding blankets, robot covers, aircraft parts, expansion joints, etc.)
  • Mixing of high-temperature resistant cements, adhesives and moldables

Many of the end products we sell are comprised of at least two components from our different divisions, which eliminates costly outsourcing and ensures a higher level of quality control for our customers.

Our products are manufactured with environmental protection, health and safety in mind. Many of our products are designed to protect personnel and equipment, while others are designed to reduce emissions and protect the environment. In 2010, after nine years of development with our marine response partner, the Hydro-Fireboom was launched in the Gulf and used to clean up 85% of the oil that came to the surface during the Deepwater Horizon Oil Spill.

As detailed in the video, we also worked with NASA/JPL to create a “ballute” for the Mars 2020 Lander, a balloon/parachute that is an isotensoidal structure designed to slow down the lander’s approach to Mars and create a safe landing. Mid-Mountain’s first foray into the aerospace industry was manufacturing insulation for the rocket nozzles on the Space Shuttle Columbia. Currently we manufacture a number of parts for aircraft such as thrust reverser seals, cargo containment covers, firewall blankets, vapor barriers and sound insulation, to name a few.

Our keen knowledge of materials science combined with our experience allows us to approach any applications challenge with confidence and assurance. Our approach is that it can be done, and we have provided our customers with both standard and custom products for 45 years. We hope you enjoy the overview and look forward to providing you with a solution for your application.
