Any Experience with CNC Routing Jain Excel Integral PVC?

[Ross Moshinsky]

I have a sign project for the CNC and I wanted to use 1" Komacel PVC. The issue is my distributor doesn't have it in stock and it might not be in stock in time. They do have some Jain Excel Integral PVC in stock. Anyone have any experience with this material?

It's roughly 40"x27". The sign is a pretty basic painted sign with V-Carved letters. One spot will have pocketed letters. Depending on how it came out I was going to leave the letters the natural white from the PVC or more likely paint them white again to give a nice bright finish. I didn't want to deal with HDU on this project as it requires more work finishing it. I also wasn't very concerned with the weight as it's less than half a sheet. If the sign was larger, I would have spec'd HDU.

So, Jain PVC okay or should I switch to Duna 15lb HDU?

Both of those, as well as Sintra and Komatex are a similar product, closed cell PVC foam and should machine about the same. i have not used it myself but have used the other 3 brands. Painting requires a plastic primer, but I have many PVC Foam letters and logos on outside walls that have lasted a long time.
