Dunmore

What Dunmore does

Dunmore is a US-headquartered engineered films manufacturer that designs and produces coated, metallized, and laminated flexible substrates for demanding industrial and aerospace applications. Founded in 1970 by Michael Sullivan in New Jersey and now headquartered in Bristol, Pennsylvania, the company operates three ISO 9001:2015 certified manufacturing facilities across Bristol and Brewster in the United States and Freiburg in Germany, employing over 200 people. Its core technology base is roll-to-roll flexible substrate processing, spanning vacuum metallizing (aluminum and copper up to 82 inches wide), precision coating (slot die, solvent- and water-based), multi-layer laminating up to 5 layers and 80 inches, foil converting, plasma, and corona treatment. The product portfolio spans aerospace MLI films (Starcrest™), Kapton® polyimide tapes, ESD protection films, aircraft interior and insulation films (SkyCrest™), photovoltaic backsheets (DUN-SOLAR™), security and tamper-evident films (DUN-GHOST™, DUN-GUARD™, DUN-SECURE™), inkjet and label films (DUN-JET™, Aqua-Jet), and specialty films for cryogenic, fluoropolymer, antimicrobial, battery, and surfacing applications.

Dunmore earns revenue primarily through custom contract manufacturing and proprietary branded film products sold to enterprise customers. Pricing is quote-based, project-specific, and tied to multi-year contracts in many aerospace programs. The business model combines toll coating, metallizing, and laminating services for customers who supply their own substrates with proprietary product sales and custom collaborative development through a four-phase stage-gate process (Lab, Pilot, Scale-up, Commercial Production). Customers include major space and aerospace primes (Airbus Defence and Space, Thales Alenia Space, EADS Astrium, Boeing, NASA/JPL, ESA contractors), supported by long-tenured distribution and OEM partners such as Proline Performance (10+ years), Soditech (35+ years), and Aerospace Fabrication & Materials (25+ years). Secondary revenue streams serve solar module manufacturers, packaging converters, label and graphic arts firms, and electronics producers, with products shipped to over 25 countries.
