MYcell rigid PVC foam
Rigid foam used as the core of sandwich structures for composite materials.
The foam is made of 100% closed polyhedral cell cross-linked PVC, free of chlorofluorocarbons. It is the main core material used in shipbuilding for the construction of yachts, motorboats, catamarans and boats. It is excellently used in high-end sport boats such as canoes and kayaks. It has DNV and ISO9001 certifications.
- Highly resistant
- Lightweight
- Low resin intake
