Tommy Tape is manufactured from a specially formulated silicone rubber compound. This amazing tape is not sticky at all - but within minutes of wrapping an object, it begins to fuse to itself, forming an air and watertight bond. It stretches to three times its length, so you can wrap even oddly shaped items and will not crack or unravel during expansion or contraction. It has thousands of uses in all sorts of industries and in the home. Adhesive free, Tommy Tape has no sticky side, so won’t leave sticky residue after removal. Resistant to UV, salt, oil and chemicals and even extreme temperatures.
