With our smart platen, there is a 1/8 inch layer of 30 durometer closed-cell foam.
This isolates the belt from the machine ground, using our 3M belts static electricity builds up.
This will discharge thru your fingers for a little wake-up jolt if your the ground.
Either you can spray some laundry static guard on the back of the belt
Or you can use Aluminum Tape which is a good replaceable wear surface.
works well
