This past weekend I installed quad boxes in a pop-out from Cobra (Thailand) and another from China. I was impressed with the EPS from the Cobra factory. The beads were fused so beautifully, they were no longer round beads, but smashed polygons with all flat sides matting perfectly with each other. Not a hint of daylight between any of the former round beads.
A) the Cobra board
B) the Chinese board
C) Carpenter foam in NC. Construction grade 1 lb.
The enlighting part of seeing these foams for me, is that the only surfboard EPS blank I’ve had my hands on in the US, was a SUP built in California using a big name blank brand. I got a peak inside this US built SUP when I installed a Gore-Tex vent. The EPS beads were not like the foam from Cobra. I could see loose beads and daylight between them after I used the hole saw on the board.
What US blanks companies are making EPS as pretty as this stuff from Cobra?
