PVC Foam Core is engineered to perform reliably across almost all major composite manufacturing processes, making it one of the most process-friendly core materials available. In vacuum infusion, the foam’s dimensional stability plays a significant role. It maintains consistent thickness under vacuum pressure, ensuring resin flows uniformly across the fibers and core. Its surface cell structure also allows controlled resin uptake, leading to strong bonding without excessive resin absorption.
In hand lay-up, PVC Foam Core is valued for its ease of handling. It can be cut, shaped, and positioned without fracturing, and fibers adhere easily to its surface. This makes it suitable for custom or low-volume production, especially in marine and industrial fabrication.
During Resin Transfer Molding (RTM), PVC Foam Core withstands the injection pressures and temperature shifts common in the process. Its resistance to crush and deformation ensures that the final component retains precise geometry.
For prepreg lamination, the foam must tolerate elevated temperatures during cure cycles. Many grades of PVC foam are formulated specifically to resist thermal expansion, outgassing, and dimensional changes that might otherwise affect laminate quality.
Across all processes, PVC Foam Core delivers predictable behavior, high bonding performance, and stable mechanical properties, making it a reliable choice for manufacturers using diverse production methods.
