Review on Bertech Heavy Duty High 🧼 Temperature Rubber Janitorial & Sanitation Supplies by Ryan Olsen

Not very good, but good. It's measured as a good material (3M etc) so the surface resistivity is as expected. The top and bottom are textured, but they're heavy and sticky enough not to move. The only problem is that it discolors at high temperatures. When I hold a soldering iron it turns black. It doesn't melt like cheap vinyl, but it does stain. However, it is a good inexpensive alternative. I am using an old piece of high quality product to solder and make this.
