It is hard to think that there could be much be done to foam, but Varial Surf Technology introduced this month the new Varial Foam, which is made from an advanced aerospace formula and a new chemistry to surfboards all together. The foam is reported to be 25 percent lighter and 20 percent stronger as compared to a standard polyurethane blank with a stringer.
This means that it can eliminate the need for a stringer or any other strengtheners that current surfboards require, while the compressive strength of the foam makes the board highly responsive to riders by transferring energy directly through the core to the water’s surface.
