What Insulation do you use?
-
I have a Creatbot F430 of which I'm putting on the finishing touches of a Duet upgrade. The enclosure is built like a tank yet on the other hand it is quite a heat-sink and takes a long time to get up to 60˚C. Eventually the whole box is quite warm to the touch radiating most of the heat outside the box.
I would like to line the inside with some sort of thermal barrier. What have some folks been using and liked.
Thanks in advance.

@brs i've used cork for insulation...
-
@brs corrugated cardboard is another possibility. If you are looking for something that does not increase fire risk then you could consider fireproof insulation board.
-
I use a combination of PIR insulation foam/board and open-cell polyurethane foam for my side panels. The Stratasys 1200 series printers also used (what looks and feels like) open-cell polyurethane foam as well.
-
I extensively use self adhesive foiled rubber foam. Its the stuff that comes sometimes with heated beds for insulation. Its actually manufactured as automotive engine bay sound and heat insulation. In my opinion this knocks the socks off all other options. Easy to install, cheap and very effective. My enclosures are all passively heated and achieve 74degrees consistently. Heres the aliexpress link. https://www.aliexpress.com/item/1005001475455913.html?spm=a2g0o.order_list.0.0.21ef1802dXxfYm

Just the kind of stuff I was hoping to find.
T H A N K - Y O UIs that 74˚C?
Searching amazon for "Car Hood Engine Firewall Heat Mat Deadener" brought up several offering from UXCELL. Delivery Monday is better than late July with aliex. -
In the past I used reflective bubble wrap roll like this one, when I wanted to print ABS on an open frame printer.

@zapta
I had looked at some of that bubble wrap but was concerned about flammability. The Car Hood Foam seems to be flame retardant. Does the bubble wrap sustain fire? -
@brs The stuff you are looking at is generically called "Multi Foil Insulation" here in the UK. So you might find something suitable at a better price if you use that as a search term.
-
Yes, providing you do a good job having a low leakage box, have some convection/circulation fan and keep the volume down, 74degrees C is achievable with the rubber foam insulation I describe.

@brs Where are you based. I have quite a lot in stock I could share.

-
@zapta I just tried burning it with a blow torch. It extinguishes within 1-2seconds once the torch flame is off which seems good to me. However, it would be good to know how to test this against standards such as UL94 or equivalent. Perhaps someone can advise?

Washington State but never mind as I ordered some on Friday evening, it arrived early Saturday morning and it was installed Saturday afternoon. Got the 5mm foam and I also put a torch to a bit of it and found that it did not sustain flame once the torch was removed. Thanks though.

@bubblevisor, if yo will buy from a repuatable vendor or manufacturer, you may find safety information you can trust. E.g. https://www.mcmaster.com/insulation/insulation-type~sheet-strip/heat-reflecting-air-bubble-duct-insulation-sheets/
