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.
PTC will offer a virtual desktop environment for its Creo product design applications, potentially freeing engineers to run them from remote desktops on a variety of operating systems and mobile devices.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This radio show will show what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
