New double-coated adhesive tapes from Avery Dennison Specialty Tape Division could soon force unwanted bacteria to go swimming with the fishes. The tape incorporates a biocide to prevent bacterial and fungal growth in a variety of automotive, appliance, and electrical foam-bonding applications. Called FT 8395, the tape features a rubber-based formulation, and is available in two versions, one with 80# densified Kraft liner and the other with 12 point board line.
Gaskets don't have to be so darn creepy. Form-in-place gasket tape from W.L. Gore & Associates is made entirely from a PTFE that's been expanded in multiple directions for a reduction in creep relaxation and a retention of its thickness profile under compression. Called GORE-TEX BG, the tape comes in 1/8, 1/4, and 3/8 inch thicknesses and in widths of 1/4 to 6 inch. Applications include large-diameter or misaligned flanges as well as any other sealing applications that have to contend with surface irregularities or gaps. As it's made from PTFE, the tape resists a wide range of chemicals (pH 0-14), except for molten alkali metals. Operating temperatures range from -450 to 600F.
A line of three pressure sensitive tapes from Adhesives Research Inc. tackle a variety of mobile-phone assembly jobs. ARclad 8314 and ARclad 8901 are both 8-mil-thick, double-sided, acrylic bonding tapes—the former with a clear polyester carrier film and the latter with a black polyester carrier film. They address mounting and bonding tasks all over the phone—including nameplates, lens gaskets, loud speakers, and battery packs. A third double-sided acrylic tape, ARclad 7992, comes in an even thinner 5-mil thickness. All three tapes conform to curved surfaces.
