3M™ VHB™ Tape 4950 is a 45 mil thick firm, double-sided, pressure-sensitive, closed-cell acrylic foam tape with a paper liner. 3M™ VHB™ Tape eliminates the need for rivets, bolts, screws and welds. It helps provide handling convenience, cushioning, damping, and impact resistance.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 cant 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 helps provide these tapes with their unique characteristics. The acrylic chemistry helps provide outstanding durability performance. 3M VHB Tape 4950 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.
