For years, polyurethane surfboard foam
was the staple medium for surfboard shapers around as it was easier to work with and lighter in weight compared to the next best thing at the time which was balsa wood surfboards
. EPS Surfboard Foam
(Expanded Polystyrene) had been toyed around with by a few select shapers, but didn't really take off until the closure of the largest Polyurethane foam manufacturer (Clark Foam) in 2005.
Today, more and more surfboard brands offer models in both Polyurethane and EPS, with some even moving to 100% EPS foam
, as well as some blending the two such as DHD
and their new Epoxicore
EPS is lighter, slightly more buoyant and can feel lively in the right conditions. For more information, look into articles like Poly or Epoxy, Which One is Best
, and Surfboard Construction Types
which go deeper into construction methods and materials.
