FAQ

Is PVC foam fire resistant?

FR grades are available depending on regulatory requirements.

How is foam bonded in vertical bulkheads?

Using epoxy or MMA adhesives and fiberglass laminates.

Does PVC foam cause print-through?

Proper curing and surface finishing minimize print-through effects.

Is thermal expansion an issue?

Minor; engineers account for it during layup.

Does PVC foam compress under vacuum?

Quality foams have very low compression under vacuum pressure.

Can foam be layered in multiple densities?

Yes. Multi-density configurations optimize weight and strength.

Does PVC foam require vacuum bagging?

Not always, but vacuum bagging improves bonding.

What density is used for transoms?

160–250 kg/m³ for compression strength.

What density is used for decks?

60–100 kg/m³, depending on span and load.
