Details
What is FR4 Material?
FR4 is a widely used high-performance composite material made by combining woven fiberglass cloth with epoxy resin through a high-temperature and high-pressure lamination process. The name “FR4” stands for Flame Retardant Grade 4, indicating its excellent fire-resistant properties in accordance with industry standards.
Why Choose PET Foam Core?
PET foam (polyethylene terephthalate foam)—an eco-friendly, recyclable material—is widely selected as a core material due to its exceptional balance of lightweight structure, mechanical properties, and long-term durability. As a rigid, closed-cell foam, it plays a pivotal role in enhancing the overall performance of sandwich panels. By integrating PET foam as the core, FR4-faced PET foam sandwich panels achieve an optimal combination of lightweight design, structural strength, insulation capabilities, and environmental responsibility.
