Foam tape is a kind of tape made of foam material as the base material, coated with solvent-based or hot-melt pressure-sensitive adhesive on one or both sides, and covered with release paper. It not only has the inherent adhesive function of tape, but also has unique characteristics due to the properties of foam material, such as sealing, shock absorption, noise reduction, gap filling, waterproofing, and compensation for thermal expansion differences of different materials.
