Delaminating MDF

[CHJ]

Can I tap into the experience of you folks that regularly use MDF for Furniture, Kitchen builds etc.
My knowledge of the stuff goes no further than the use of the odd sheet as a panel with 25mm being the thickest I've used in double layers to build up heavy worktop.

Usually in cheap and cheerful whatever is available or comes my way as off-cuts, and once to my surprise as a metal reinforced moisture resistant version when asked to help someone who was having problems.

I'm currently involved with a project that needs to be profiled out of 30mm stock, using wood is rather prohibitive in cost and has it's own problems with grain orientation, but using 'standard' MDF is proving none viable as a small percentage of the 'End Grain' profile needs to take staple type fixings and this readily delaminates as I would expect, (fixings are too numerous and impractical to insert dowel plugs)

Before I bite the bullet and fork out on a sheet of Moisture Resistant stuff to see if this is any better can anyone advise if it is likely to be better bonded or more importantly what Grade of MDF (or is there such a thing as HDF) that is likely to be better in this respect that I should be considering.

Remember I need 30mm thickness stock.

I'm not aware of any form of MDF that doesn't have a tendency to delaminate if you put fixings such as screws, nails or staples into the edge. A fixing designed for use in this manner is a Confirmat screw; they work quite well, but I suspect from the description of you're task these aren't at all appropriate.

I wonder if one possible option might be to join and glue a solid wood edging to your MDF panels, then work the moulding, and finally staple on whatever it is you're attaching to this? Slainte.

Thanks Richard for the thought, if it was a straight edge this is what I would do but unfortunately the project is contoured in more than one plane, currently experimenting with treating 'end grain' with penetrating adhesives, thin CA works but of course both cost and handling (hazard) in such volumes is out of the question.

I can see why folks ignore the ethics and go abroad to producers with access to cheap wood and labour.
