PMI foam core

PMI foam core combines ultra-low density with exceptional mechanical strength, making it ideal for lightweight yet durable composite structures. It withstands temperatures up to 200 °C, absorbs minimal resin thanks to its fine closed-cell structure, and offers superior impact and fatigue resistance compared to many other core materials. Its compatibility with advanced manufacturing processes such as RTM and vacuum infusion ensures precision and efficiency, while its non-combustible nature enhances safety. With these properties, PMI foam core is a premium choice for demanding industries—from aerospace and automotive to wind energy, rail, sports equipment, and medical devices—where strength, thermal stability, and long-term durability are essential.

PMI foam core provides several environmental benefits that make it a more sustainable choice. Thanks to its low resin uptake, it reduces the use of harmful substances and minimizes production waste during composite manufacturing. Certain PMI types are also recyclable, and with increasingly sustainable production methods, they contribute to the circular economy. In addition, PMI foam does not emit toxic gases during processing or use, lowering both environmental impact and health risks.

PMI foam core is a high-performance material widely used in advanced industries such as aerospace, automotive, wind energy, rail transit, sports equipment, and medical devices. Its unique combination of ultra-low density, high strength, thermal stability up to 200 °C, and excellent fatigue resistance makes it ideal for applications where weight reduction, durability, and reliability under demanding conditions are critical.

PMI foam core should be stored in a dry, cool, and well-ventilated area, protected from direct sunlight, heat, and moisture to preserve its mechanical strength and structural stability. Avoid extreme temperature fluctuations, and handle with care to prevent mechanical damage—especially when moving large or thick sheets, where proper lifting equipment is recommended. For transport, ensure stable securing and padded protection to avoid deformation or breakage. Always keep the material in its original sealed packaging to protect it from dust and moisture, and check its condition before processing, particularly after long storage. Following these guidelines helps maintain the foam’s structural integrity and performance over time.
