The DeWAL pressure sensitive tape line includes a group of specially constructed products made for use in oil and gas exploration and production. DeWAL oil and gas tapes provide the temperature and chemical resistance of Teflon® FEP and PTFE backing films combined with DeWAL proprietary adhesive systems. The intrinsic frictional qualities of these backing materials allow for smooth operation, even under the most demanding application conditions. The Teflon® FEP film is optically clear and offers excellent dielectric properties. There are three tapes in this product family: D/W 704-2 consists of a two mil FEP film coated with a high-temperature silicone adhesive system. This product is a self-wound tape without a release liner. D/W 706-2 is also a two mil FEP and silicone adhesive product. The non-adhesive side of D/W 706-2 is chemically treated in order to provide greater bond strength when it is applied to itself. D/W 245-5 is constructed from five mil PTFE film and a specially formulated acrylic adhesive. This adhesive is capable of withstanding temperatures up to 400 degrees F. The PTFE film is etched on the back side, providing a bondable surface.
