3M does it differently-because every sealing and holding challenge is different. Permanent and temporary tapes in a wide assortment of backing materials and adhesives provide the most effective solution to your sealing and holding challenges.
Where tensile strength is a requirement, you can't do better than a glass cloth backing. This type of backing can have tensile properities seven times high than typical polyester.
Polyester backing can be as thin as 1.0 mil, yet still have very high dimensional strength properities. Excellent for applications that require a thin caliper such as butt splicing.
Specialty tapes with non-woven backings that are air permeable. Keeps foam-in-place insulation inside door and applience cavities, at the same time helping eliminate voids.
