solarez: Sponge-Rez works on all types of bodyboard materials including Ethafoam, Surlyn, EVA, Vinyl, and Arcel,however it will melt styrofoam (EPS) cores.

We would suggest our Camie 373 spray adhesive for bonding polystyrene to any other foam product we carry.

Camie 373: While Camie 373 can also be used on our closed-cell foams, we suggest this product for use on the polystyrene/EPS foams the 3M Super77 would have damaged.

I'm finding it hard to find polypropylene 1.3 density in Spain
so I've been spinning my head and using materiel that I can find.
  hdpe for now, not in a small format, but everything is to keep looking

A friend told me that whenever I put fiberglass and resin in a paipo, being so small compared to a surfboard I will kill flex, I will always stay rigid, I put the layers that I put on. This idea may be interesting, as there is a substitute for hdep. that is used in the bodyboard at the bottom, but e has happened to put one in the top to protect the xps to the hits, since this does not have the properties of pe and pp. I think this is already used in a soft surfboard

Flex may add soft landing to a bodyboard when landing airs, but other than that I find the stiff fiberglass board better at everything else. faster and turns better.

A friend has left me a very old bodyboard to look at compatibilities of materieles and polyester resins ,,, I really do not like anything the rubbery touch of the bodiboard, I do not find gradables cojerlos, will be for many years accustomed to the hardness of the fiberglass

If a bodyboard has 57mm of fat more or less, what combinations of foam eva have you done? To put a 20mm foam would be too much?

In my search for cheap materials and fast manufacturing I found PVC celuka foam.
is a foamed pvc sheet which makes it lighter than pvc, do you know any of this?
I think a thickness of 4mm would be fine
do you know this material? what do you think?

es

en mi búsqueda de materiales baratos y de fabricación rápida he encontrado PVC celuka foam.
es una lamina de pvc espumado lo que hace que sea mas ligero que el pvc, sabeis algo de esto?como prdria pegarlo al xps
creo que un espesor de 4mm estaria bien
conoceis este material? que os parece?
