3M™ Vinyl Foam Tapes Series 4700 are a flexible, black, medium density, closed cell foam with a pressure-sensitive acrylic adhesive on one side. The adhesive is protected by a 0.004 inch (0.1 mm) thick white, silicone treated paper liner which allows for die cutting without having to laminate another liner to the foam.
