The 3M™ VHB™ Tape 5952 Black uses modified acrylic adhesive on both sides, combining strength, conformability, and adhesion to make one of their most capable and well-rounded tapes. For those wondering about the difference between 3M™ VHB™ Tape 5952 and 4950, the 5952 has a high tensile strength, meaning it can withstand higher stress levels without breaking. This feature makes it the better option for applications that require higher bond strength. The 5952 also has a higher elongation than the 4950, so it will stretch more before breaking. This tape may be better for applications with thermal expansion or mechanical stress.
