Sintra (Expanded PVC) Sheet for Skin
Posted: Sun Jan 03, 2021 5:41 pm
Hey All,
Been lurking for a few weeks now while considering making my own square-drop concept over the next year. The amount of information in here is mind boggling and I've begun to lean towards a Foamie-hybrid based primarily on my TV (Crosstrek) limitations. Hybrid because while I understand the PMF works great for people but I'm willing to save for a bit and spend a little more if this concept proves out, I also have a passion for overcomplicating my life. Truly, I have been really drawn to a CNC cut/routed panel system for cleanliness and easier construction on my end.
I know people have used a laminated XPS foam/Alu composite for construction but I was trying to come up with lighter (if possible) and cheaper options than using an aluminum composite. I've been diving deep into sign materials and came across Sintra (expanded PVC) sheets which are designed for long-term outdoor use and I can't find any posts regarding this type of material on the forum. Anyone test/have long term experience with this as an external skin?
I think I'm going to order some small pieces and mock up some laminations to sit out in the sun/weather for a few months since I won't be starting a build any time soon. It appears that a 2mm sheet (4ft x 8ft) is apx. 9.2 lbs so it the weight seems relatively reasonable when compared to PMF or similar skin options.
I am also considering a printed vinyl wrap as a final exterior layer for both color/graphics (I'm a designer...can't help myself) and additional UV resistance. Would love to hear some thoughts!
Here's the product information: https://www.coastalcreative.com/product/sintra-board-pvc-signs/
And an example of cost: http://www.artsupply.com/foamcore/sintraboard.htm
Thanks and looking forward to diving deeper into the forum!
