What is PVC Foam Core？

PVC Foam Core is a closed-cell structural foam widely used as a core material in sandwich composite structures.
 
It combines low density with good mechanical performance, providing an efficient balance between weight reduction and structural strength.
 
PVC foam core is compatible with a wide range of resin systems, including polyester, vinyl ester, epoxy, and polyurethane, and is suitable for various composite manufacturing processes.
 
Its closed-cell structure ensures low water absorption and stable performance in demanding environments.

Why Choose PVC Foam Core？

1. Lightweight, Strong, and Durable
China PVC foam core offers an excellent strength-to-weight ratio with high compressive, shear, and bending strength, along with outstanding fatigue resistance for long-term structural performance.

2. Low Water Absorption and Easy Processing
The closed-cell structure resists water ingress and maintains stable properties in humid or marine environments. Compatible with polyester, vinyl ester, and epoxy resins, and suitable for common composite manufacturing processes.

3. Cost-Effective and Widely Proven
China PVC foam provides an optimal balance of performance and cost and has been widely used in marine, wind energy, transportation, construction, and industrial composite applications.
