Melamine Foam in Canada?

Postby Yeti on Sun Jan 16, 2011 6:06 pm

Anyone know where in Canada I can find melamine foam for boiler insulation? Apparently McM-Carr does not ship to Canada?

Found 1 or 2 manufacturers of Melamine sheets, no luck in getting an answer. Anyone in the US with enough Melamine Foam left over from a job to do an Elektra A3 boiler and willing to part with and ship to the frozen north?

Thanks,
Dave

Why don't you try something else? I used Insul-brite on my Rancilio S-20. It's the material used inside oven mits. It's random-weaved so cutting out holes for boiler protrusions is easy and has no sharp fibers. It's also cheap. I bought 1 meter to do my machine, costing $9, and I had enough for a double-wrap. If you want seams for removal, you can used double sided sewing tape for permanent seams or adhesive-back velcro for removable seams... Available at all fabric stores. Also, doesn't collect water so there's no mold growth (entirely plastic-based).

@sketch: Melamine is proven and a clean install, Insul-bright may have potential, but I thinks its limits are close to the boiler operating temperature?
Got any specs on insulating properties etc

I haven't had any problems at all with the insulation on my boiler, the idea has been applied to other rebuilds on this forum as well (where I got the idea). It's not to say other solutions aren't nicer, it's just cheap, effective (especially as a double layer) and easy to come by.

I used Insul-Bright as well, and you can't beat the cost ($4 for a yard, on sale, enough for 4-5 machines) and the ease of installation (no itch factor, no weird smells, very robust)

Boiler temperature is, by any stretch of imagination, a very low temperature for the mylar and polyester in Insulbright, and well below the operational temperature of the lower temperature component
(polyester), softening around 200C and melting at 250C. Boilers at ~120C are not an issue. The best part is that a boiler, thanks to the design of the beast (pressurestat), can't go above dangerous temperatures anyway

for more details, see also http://coffeesnobs.com.au/YaBB.pl?num=1255582897

Sometimes I look at the materials used to insulate boilers used on this forum, and I scratch my head and wonder why people would want to spend that amount of money for such a low temperature (try working with ceramic kilns, for reference :-) )

I cut a strip 2-3" higher than my boiler and twice as long as the circumference. Then I slowly wrapped it around the boiler, pulling it thru an "opening" in the pipes and wiring, wrapping it around the boiler twice. My duty cycle is much better, and the machine gets warm faster and stays warm longer between uses.

Just make sure you do not wrap any wiring or the pressurestat, as the increased temperature won't prolong their life. And make sure you do not block the air flow in the machine, especially in the lower part, around the electronics (the lower part is the cooler, but only if convective air motion keeps drawing fresh air from the bottom)

So who are the recommended Canadian sellers for any of these materials?

What I was told is that it is not sold up here as it is not 'approved'...CSA? (quoting a weak Acklands-Grainger response).

Also sold as Basotect up here through BASF, but they wouldn't sell to schmucks like me :roll:

Gave up and used InsulBright - ovenmit insulation.

Fabric stores. That would mean Fabricville in our case but I haven't checked yet.
