The double-sided structural mounting tapes we sell are either VHB (Very High Bond) tapes from 3M or DC-UHB (Ultra High Bond) tapes from JVCC. They are constructed of either firm acrylic foam or softer more conformable acrylic foam.
Double-coated, AKA double-sided, polyethylene foam is also sold for less demanding mounting applications.
