3M VHB Tape Structure

- Jan 26, 2018 -

VHBTM Tape is 3M with a unique solvent-free manufacturing technology for the production of polyacrylic acid ester double-sided foam tape, foam core materials and surface adhesives are all composed of polyacrylate viscoelastic body, rather than on both sides of the foam core coating adhesive, which is VHBTM tape products and common foam tape the biggest difference, Can be called "solid glue", this special structure gives the adhesive tape special overall viscoelastic, the adhesive tape can effectively remove the stress in the adhesive joint through the mechanical relaxation of the adhesive tape, thus effectively protecting the sticky wiring, the foam core of the VHBTM tape is 100% full closed-hole structure, and neither water nor air can pass.
