Surfblanks Australia formulates and manufactures various densities of block and sheet foam.
The basic ingredients are the same as those used in the surfboard foam systems. The difference is that much heavier densities are required for block and sheet.
The foam appears white and very firm. The foam resists all solvent attack, so is very versatile in most applications.
The block is made in a variety of shapes to suit end users, anywhere from a 1' x 1' x 1' cube to a 9' x 2' x 5'' slab.
In special cases, customers can supply their own light plywood or heavy cardboard moulds for one time filling, after Surfblanks has quoted approx cost.
Blocks (7lb) from cardboard and wooden boxes.
Pictured are two blocks - the first was produced from a thick walled cardboard box - the second from a partical board wood box.
The long block is the one that be sawn to any length, say 1, 2, or 3 feet.
Any block or slab can be sawn. Sawn faces can be sanded to a fine finish.
