EPS foam blanks are surfboard cores made from expanded polystyrene foam, engineered for lightweight performance, buoyancy, and epoxy compatibility. Their fused-bead cell structure provides exceptional float and flex efficiency but requires precise lamination control to prevent delamination. EPS blanks are typically paired with epoxy resin systems and stringerless or composite constructions to enhance flex and reduce weight. Compared to PU blanks, they deliver greater flotation and energy return, ideal for small-wave and performance epoxy boards.
Shapers refine EPS foam blanks through bead fusion, density grading, and reinforcement pairing that maintain responsiveness, feedback, and control.
