CA Composites PVC Foam Core is a high-performance, closed-cell structural foam designed for demanding sandwich panel applications. Available in densities from 45 to 250 kg/m³, it gives you the flexibility to optimise weight, stiffness and cost for your exact requirements.
- Virtually zero resin absorption — closed-cell structure keeps your laminate lightweight and resin usage predictable
- Compatible with all major resin systems — epoxy, vinyl ester, polyester and more
- Prepreg compatible — handles processing temperatures up to 120°C for 30 minutes
- Exceptional chemical and moisture resistance for long-term performance in harsh environments
- Wide service temperature range: −240°C to +80°C — suitable for cryogenic, marine and elevated-temperature applications
- High compressive strength and stiffness-to-weight ratio — ideal for structural sandwich construction
- Manufactured to international standards
Typical applications: marine hulls and decks, wind turbine blades, sports equipment, high-speed rail interiors, automotive panels and aerospace structures.

Surface Finishing Options
| Finishing | Description |
|---|---|
| Simple Plain | Standard unmodified foam sheet |
| Perforated Foam | 2–3 mm diameter holes drilled 20 mm apart. Assists in expelling air and letting resin flow during lamination. |
| Grooved Foam (VIC) | Shallow 2 mm deep cross-cuts on one or both sides. Groove spacing 20 × 20 mm. Ideal for vacuum infusion. |
| Grooved & Perforated | Grooved with perforated bleeder holes for enhanced resin distribution. |
| Double Cut (DC) | Sheets cut 50–60% through thickness. Applicable for curved parts with low resin intake. |
| Double Cut with Holes | Double cut with 2 mm diameter perforations for curved parts requiring resin flow. |
| Contoured with Scrim | Cut to depth leaving 2 mm bottom intact, 30 × 30 mm slots. Fibreglass cloth bonded on the bottom side. |
| Contoured Scrim with Perforation | Contoured with scrim plus 2 mm perforation holes for maximum conformability. |
