Description
This premium 75G infusion grooved PVC foam sheet is a professional-grade structural core material designed for high-performance composite construction. Engineered for use with resin infusion processes, the sheet features precision grooves that promote consistent resin flow and reliable bonding throughout the laminate.
Ideal for industrial and commercial applications, this lightweight yet robust PVC foam core is commonly used in marine, transportation, construction and wind energy structures. Available in a choice of thicknesses and sheet sizes, it provides excellent stiffness-to-weight ratio and long-term durability in demanding environments.
Product Features
- Available thickness options: 10 mm and 25 mm to suit a range of structural requirements.
- Offered in two practical sheet lengths: 540 mm and 1080 mm for flexible panel layouts.
- Choice of sheet widths: 505 mm and 1020 mm to optimise coverage and reduce cutting waste.
- Infusion grooved surface to support controlled resin flow and thorough wet-out during vacuum infusion.
- Closed-cell PVC foam core providing excellent stiffness and low density for lightweight structures.
- Consistent 75G infusion grade for professional composite manufacturing and repeatable performance.
- Easy to machine, cut and shape using standard composite fabrication tools.
Key Features and Benefits
- Lightweight structural performance helps reduce overall component weight while maintaining strength and rigidity.
- Grooved core design improves resin distribution, reducing the risk of dry spots and voids in the laminate.
- Closed-cell PVC construction offers excellent resistance to water absorption, supporting long-term durability.
- Versatile sheet size options allow efficient nesting, minimising offcuts and material wastage.
- Good machinability enables accurate shaping to complex contours, saving installation and fabrication time.
- Stable, uniform core properties promote consistent quality across multiple production runs.

Frequently Asked Questions
Can this PVC foam sheet be used with standard vacuum infusion resin systems?
Yes, this 75G infusion grooved PVC foam core is designed for use with common vacuum infusion resin systems, including polyester, vinyl ester and epoxy resins. Always follow your resin supplier’s guidelines and test in small sections when using new combinations of materials.
How do I cut and shape the infusion grooved PVC foam sheet?
The sheet can be cut and shaped using standard tools such as sharp utility knives, hand saws or fine-tooth power saws. For best results, support the sheet during cutting, use light pressure to avoid crushing the foam, and clean away any dust before lamination.
Is the foam core suitable for outdoor and marine environments?
The closed-cell PVC structure offers good resistance to water absorption and is widely used in outdoor and marine composite applications. However, it should always be fully encapsulated within a suitable composite laminate to protect it from mechanical damage and environmental exposure.
