Okay Mike, here is what I have. It is sold in the USA by International Vinyl Corporation and I believe the product name may be Flextech. I comes in 13' 2" widths but is easily seemed of just butted up next to the next piece. Here's the poor website for it: http://www.ivcgroup.com/us/Products-...ode=selection# They have a specification link on this page.
I find that it is just the right amount of padding for me. However I mainly bought it initially for protecting chisels I might drop and for easy clean up. It had a bit of static cling for the first week or two but that subsided to zero. In your humidity I doubt you will ever see any.
If I am flattening a large piece of material with a plane or standing relatively still for long periods of time working on inlays, I will pull out my thick 30" x 50" anti-fatigue mat that I bought before I found the Flextech. I find it too small and too cushy for everyday use... and it was a couple hundred dollars.
Hope this helps you find the product.
