3M™ VHB™ Tape 4955 is a 80 mil thick firm, double-sided, pressure-sensitive, closed-cell acrylic foam tape with a polyethylene terephthalate (PET) film liner. 3M™ VHB™ Tape is comprised of closed-cell foam with pressure sensitive adhesive on two sides. This unique combination offers benefits that screws, rivets, welds and other types of mechanical fasteners just can’t match. In many situations, they can replace other permanent fasteners. They are made with acrylic foam which is viscoelastic in nature. This gives the foam energy absorbing and stress relaxing properties which provides these tapes with their unique characteristics. The acrylic chemistry provides outstanding durability performance. 3M™ VHB™ Tape 4955 has a general purpose adhesive on both sides of firm type foam and is typically used for metal, glass and high surface energy plastic substrates. It provides handling convenience, cushioning, damping, and impact resistance.
