Processing
ROHACELL® PMI foam cores offer versatile processing for high-performance sandwich structures. Compatible with all major composite methods, they enable single-step bonding, reducing production time and ensuring superior finishes.
Drying
Proper drying of ROHACELL® foam sheets is essential for optimal composite manufacturing performance. This process removes atmospheric moisture, preventing negative impacts on final part quality, especially for processes above 100°C.
Heat Treatment
Heat treatment of ROHACELL® foam cores improves compressive creep resistance for high-temperature composite processing. This two-step process, including drying and extended thermal conditioning, ensures reliable performance up to 180°C.
Thermoforming
ROHACELL® PMI foam cores enable simple thermoforming of complex molded parts, from 165°C to 205°C. Various methods like compression and vacuum forming create precise, curved geometries for diverse applications.
Machining
ROHACELL® PMI foam cores are easily machined using standard equipment without lubricants, allowing precision shaping of complex geometries. High-speed methods and proper dust management ensure optimal results.
Bonding
ROHACELL® foam cores offer versatile bonding due to solvent and heat resistance, compatible with most commercial adhesives. Proper surface preparation and adhesive selection ensure strong, reliable sandwich constructions.
Prototyping Foam
ROHACELL® foam excels for prototyping due to its dimensional stability, machinability, and fine cell structure. It allows precise design models and offers a direct path from prototype validation to production.
Defense / Drones
ROHACELL® PMI foam cores provide exceptional strength-to-weight and thermal stability for defense and UAVs. Ideal for airframes, structural components, and RF-transparent radomes, ensuring mission-critical performance.
