VHB Tape Specialty Tapes Technical Data October 2014 Product Description: 3M VHB Tapes provide the convenience and simplicity of a tape fastener and are ideal for use in many interior and exterior bonding applications. In many situations, they can replace rivets, spot welds, liquid adhesives and other permanent fasteners. These 3M VHB Tapes 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. These tapes utilize a variety of specific foam, adhesive, color and release liner types to provide each product/family with specific features. These features can include adhesion to specific or a broad range of materials, conformability, high tensile strength, high shear and peel adhesion, resistance to plasticizer migration, and UL746C recognition. All 3M VHB Tapes have excellent durability and excellent solvent and moisture resistance. The tapes included in this data page have unique performance features that are not typically required in most common applications. Please refer to 3M VHB Tapes technical data sheet for applications that do not require the special features incorporated in these specialty tapes. 3M VHB Tape Products 4950 Family Tape Number Color Thickness in (mm) This family has general purpose adhesive on both sides of firm type 4914 White 0.010 (0.25) foam.
