3M™ VHB™ Tape 4951 is a 45 mil thick firm, double-sided, pressure-sensitive, closed-cell acrylic foam tape with a polyethylene terephthalate (PET) film liner. 3M™ VHB™ Tape eliminates the need for rivets, bolts, screws and welds. It is suitable for applications in temperatures as low as 0ºC / 32ºF and 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 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 helps provide these tapes with their unique characteristics. The acrylic chemistry helps provide outstanding durability performance. 3M™ VHB™ Tape 4951 bonds high surface energy substrates. It is based around the low temperature applicable acrylic adhesive system, utilized on both firm and conformable foam types, making it suitable for applications in temperatures as low as 0ºC / 32ºF.
