What material is Yin Fu adhesive vhb? What is foam tape for? What's the relationship between the two?

VHB is the abbreviation of "Very High Bond" in English, and the literal translation in Chinese is "extremely high strength bonding".

VHB is a kind of double-sided polyacrylate foam tape, which is produced by 3M Company and adopts a unique solvent-free manufacturing technology. Instead of coating adhesive on both sides of the foam core, the adhesive on the surface of the foam core is composed of polyacrylate viscoelastic body. This is the biggest difference between VHB products and ordinary foam tape, which can be called "glue stick" figuratively. This special structure endows the adhesive tape with special integral viscoelasticity. Through the mechanical relaxation of the adhesive tape, the adhesive tape can effectively dissipate the stress inside the adhesive joint, thus effectively protecting the adhesive joint. The foam core of VHB tape is 100% closed-cell structure, and neither water nor air can pass through it.
