PET Foam

PET Foam (Polyethylene Terephthalate Foam) is a high-performance, environmentally responsible core material manufactured from recycled PET plastics, including post-consumer bottles and containers. Engineered with a closed-cell structure, it delivers a lightweight yet structurally robust solution with excellent compressive and shear strength, making it well-suited for demanding applications.​ PET foam exhibits strong thermal stability, allowing it to perform reliably across a range of processing methods, including vacuum infusion, resin transfer molding (RTM), and hand lay-up. Its closed-cell composition provides inherent resistance to moisture ingress, chemicals, and corrosion, helping maintain structural integrity in harsh marine environments. In addition to its mechanical performance, PET foam supports sustainable manufacturing initiatives. It is fully recyclable and often produced with a high percentage of recycled content, making it an ideal choice for environmentally conscious composite fabrication. Overall, PET foam offers a durable, lightweight, and versatile core solution that combines structural performance with sustainability for modern marine composite applications.
