SOLIMIDE® Foams are a lightweight open-celled polyimide foam with excellent thermal and acoustic properties, enhanced fire protection, and safety characteristics. Lightweight characteristics of SOLIMIDE® Foams create significant weight savings compared to products with similar thermal, acoustic, and insulation performance. However, SOLIMIDE® stands alone when you consider weight, insulative properties, fire resistance, non-toxicity, and our best-in-class operating temperature range.
SOLIMIDE® Foams lightweight and safety benefits create a higher performing thermal and acoustic insulator compared to alternative materials: same or better insulation performance in a lower profile, lighter weight, self-supporting structure. This results in a lower total cost of ownership, enhanced customer safety, and easier installation for aircraft OEMs, passenger and cargo airline organizations, and maintenance, repair, and overhaul service providers. High noise reduction coefficients also mean passengers experience greater acoustic comfort and less ambient noise perpetuation for densely populated areas. Boyd Corporation’s SOLIMIDE® Foams are optimized for high performance applications with demanding safety and durability requirements like naval ships, commercial aircraft, spacecraft, and heavy-duty transportation.
Boyd’s SOLIMIDE® Foams are designed for enhanced fire protection and possess a wide range of ideal safety characteristics. SOLIMIDE® Foam exceeds FAR 25.856 fire resistance specifications, will not burn and emits very little smoke when exposed to flame. SOLIMIDE® Foams are flexible and stable at cryogenic temperatures and higher temperature formulations can withstand continuous use up to 300°C, ideal for applications like 3D/additive manufacturing insulation. Sensitive systems like semiconductor manufacturing and test equipment and consumer environments benefit from the low off-gassing and formaldehyde-free composition of SOLIMIDE® Foams. These insulating foams are non-toxic, possess high hydrolytic stability, and do not support microbial growth, making SOLIMIDE® Foams a durable, long term option for the harshest environments.
Boyd Corporation not only produces SOLIMIDE® Foams, but we leverage our expertise in material science, design, and precision converting to create effective laminated, cut-to-shape solutions, designed to your specification, ready for installation. Boyd offers seven variations of SOLIMIDE® Foams to meet your specific application needs. Our integration technologies allow us to combine SOLIMIDE® Foams with other engineered materials to make a multi-functional comprehensive solution to your insulation, acoustic, heat shielding, and safety requirements. SOLIMIDE® Foam is regularly combined with additional specialty materials to enhance its inherent performance strengths. It’s also heat and pressure formable, which enables mold and compress the best SOLIMIDE® Foam formulation to create highly customized, high performance insulating components tailored to your system.
