PVC foam core material is a rigid, closed-cell structural foam widely used in composite sandwich construction. It is made from polyvinyl chloride (PVC) and engineered to provide an excellent balance of strength, durability, and lightweight performance.
PVC foam cores offer high shear strength, good compressive resistance, and excellent fatigue properties. They also have low water absorption, making them suitable for marine and humid environments. Because of these characteristics, PVC foam core materials are commonly used in boat hulls, wind turbine blades, transportation panels, and industrial composite structures.
Another advantage of PVC foam cores is their compatibility with many composite manufacturing processes, including vacuum infusion, hand lay-up, resin transfer molding (RTM), and prepreg systems.
Different density grades are available, allowing engineers to select the appropriate material for specific structural requirements. Higher-density PVC foam cores provide greater strength, while lower-density grades are optimized for lightweight applications.
