Surfboard foam blanks: make your own surfboard

 

At Seabase we exclusively use and fully endorse US Blanks surfboard foam.  Historically Seabase has only been associated with high performance surfboard foam, such as Clark Foam blanks.

 

US Blanks retains the high strength to weight ratio foam.  They have recently updated their lighter 'red' surfboard foam formulae to be even stronger whilst retaining its low weight.

 

 

US Blanks manufactures a water blown, Toluene Diisocyanate based polyester polyurethane surfboard blank. We feel this combination provides the best physical properties required by a surfboard, resulting in the strongest surfboard foam possible, and yields the best performance qualities. The quality, stability and consistency of a TDI based polyurethane surf board blank has long made it the choice of the majority of board builders.

 

While there are many formulations available for a TDI based blank, we believe our formulation provides the optimum strength while maintaining ease of shaping and maximum flex. We are continuously fine tuning our formulation to supply the shaper with a foam blank that exceeds industry standards for these characteristics.

 

US Blanks has also spent considerable time and resources exploring alternate technologies in surfboard manufacturing. The rapidly progressing developments of epoxies have brought forth a very viable alternative for many board builders. As a result of our extensive research and development we are now offering our new alternative product line of “Superfused Molded EPS Foam Surfboard Blanks.” These foam blanks are currently offered in 6 different sizes, 2 different densities as well as several different thicknesses giving unlimited options to the shaper. Recognizing the importance of this technology we wanted to ensure that our customers are provided with the very best EPS foam on the market. Although our SUPERFUSED EPS product line is new, it has already set a new industry standard and we look forward to advancing and developing this technology even further into the future. 

 

To provide a truly custom surf board blank, we offer several densities from which to choose. At this time we offer every surf board blank size in every weight, however not all weights will be stocked in all sizes. Sales will dictate what sizes are stocked in what density.

 

Actual pounds per cubic foot of a given weight foam will vary with blank size due to mold compaction and skin to core ratio. The comparisons listed are based on the difference in pounds of foam used to pour each density and is an average among blank sizes.

 

The density of a blank will be identified by the color of the paint on the nose.

 

Densities are listed from lightest to heaviest:

RED, approximately 5% - 7% lighter than BLUE.

BLUE is considered our stock density and is the basis for comparison.

GREEN, approximately 4.5% - 6% heavier than BLUE 

CLASSIC, approximately 20% - 22% heavier than BLUE. These blanks will be identified with a brown tipped nose.

REGULAR, approximately 45% heavier than BLUE. These blanks will be identified with a gray tipped nose.

TOW-IN, approximately 205% heavier than BLUE. These blanks will be identified with a black tipped nose.
