Does anyone know that current surfboard foams have very toxic side effects .Have any of you read the EPA'S Data sheet on this stuff? EPS sounds better for your health and when it goes to the dump site it Bio- degrates rather than pollute the watertable with TOXIC TDI . I would BOYCOTT ANY PRODUCT MADE WITH THIS SUBSTANCE if you enjoy good health and love surfing.
Nice thing about EPS is that almost all of it is recyclable, right back to the plant you buy it from. There are also some urethane foams made with MDI which has a much lower toxcicity. Unfortunatly these are not available to surfboard manufacturers in the US.
John, please finish your thoughts. 1)Right, TDI is a very harmful substance and may cause cancer but once the liquid products have turned into foam, it is trapped in chemical bindings. The liquid is harmful, not the blown foam. 2)EPS is a foam based on polyester not a polyurethane foam. It will certainly not biodegrate. PU foam is recyclable ( pyrolysis ) as is EPS foam. But it is easier to recycle EPS since it is not a thermosetting polymer. 3)Lots of energy is needed to produce EPS. 4)As far as recycling is concerned, the worst part of the whole board is the glass layer: fiberglass is not recyclable and the cost of separating the glass and the polymer matrix ( whether polyster resin or epoxy ) is too high. 5)MDI and TDI do both contain isocyanates, they are both harmful. 6)If you have decided to boycott every product which contains TDI, you should at first get rid of your fridge, all the insolation materials used around your house, your furniture ( it could be painted with PU varnish that does contain TDI) 7)If you love surfing, boycott instead the surf clothings, shoes etc. produced overseas and flown around half the earth and get a board that lasts for 5 years. 8)And, if you find a better alternative for blanks, besides wood, please post it, i would love to make a greener board.
Dr eco. Thinks you saved me some time. Most people can read but they can't/ won't dig deep enought to find out what it really means. Ie. lead paint causes brain damage, but only if you injest it. So be carefull when you are around old paint with lead. That does not mean that all old houses should be destroyed, just because they were painted with lead based paint.
Doc, EPS is based on polystyrene not polyester. In fact Clark foam is polyester polyol based. Walker is a polyether. TDI based foams (Clark, Walker and all the Aussie foams) have 2000 times the emissions of MDI foams, so there is a difference. I for one feel that polystyrene foams do make fine boards.
Right, it is polystyrene, sorry. I thought clark uses polyurethane, carbon dioxide blown...
Send me your dinged, damaged, and yellowed.
