3M Bumpon self-adhesive elastic bumpers. Protective bumpers are practical helpers in the industrial, trade, electronics and household sectors. They quickly provide a non-slip stand, serve as spacers or bumpers. They are also ideal for absorbing vibrations and noise and also allow good air circulation. 3M Bumpon elastic bumpers are made of a permanently elastic, high-quality polyurethane elastomer and are coated with synthetic/natural rubber or acrylate adhesive. This allows them to be bonded to a variety of different surfaces.
