StruCell® structural PVC foam core offers:
• Rigid, load-bearing capability (up to 6.2MPa)
• Closed-cell structure (>95%)
• Ultra-lightweight (45-250 kg/m³)
• Extreme temperature stability (-200°C to +80°C)
• Waterproof (<1.5% absorption), DNV GL certified
• Precision CNC machining capability
• Ideal for marine/industrial structures
• Complies with international standards (ISO, ASTM)

PVC foam surface preparation must match the exact core, supplied finish and bonding system. This guide combines documented StruCell P80 density of 80 kg/m³ with controlled cleaning and validation—not a universal solvent, grit or flame-treatment recipe.
Autoclave curing combines controlled heat and pressure with a vacuum-bagged laminate. This guide explains process qualification for PVC sandwich cores, including why P200’s documented 4.8 MPa compressive strength does not define its allowable cure pressure.
Closed-cell PVC foam supports lightweight sandwich construction across marine, wind and transport applications. Explore documented StruCell® grades starting at 48 kg/m³, moisture and processing limits, and a practical material-validation checklist.
