Is this Trupan Light or Ultralite?

[Robert Rickard]

My purchase receipt says ultralite, but unsure what the edge label means. I know this is Trupan, but which density?

Trupan Lite

The Ultralite says UL

Jumping in on this post.

Has anyone ever used GP UltraStock Premium MDF or UltraStock Lite MDF for there vac table?
This is all I can find in my area.

Thanks.

Trupan Ultralight is clearly stamped Ultralight on one of the long edges. This is one way to keep imposters out when you order & the supplier insists it is ultralight when in fact it isn't. "Oh it's the same thing" - No, it isn't.

Light may be OK if using for a vacuum application. The ONLY way to tell is to put it right on top of your grid & pull vacuum with all zones open & bleeder valve closed. It should read less than 4-5 Hg" - othewise, it has too much resin content to bleed properly. Also keep in mind with vacuum that if your pump pulls 12 Hg" and you pull 5 Hg" with all zones oipen & nothing on top, the effective MAX usable vacuum is 7 Hg".

I am currently running Trupan light as a spoilboard as UL was not available. It works ok, but I certainly prefer the ultralight.
