Abstract: A conformable adhesive tape comprising a chlorinated polymeric backing carrying on one surface thereof a pressure sensitive adhesive layer, the backing layer being crosslinked whereby the backing layer is characterized as being high temperature resistant, the backing layer further being characterized as being conformable at high temperature; the adhesive layer also being crosslinked whereby to substantially increase its resistance to shear at high temperature; and a process for making same.

Abstract: A tape wrap system adapted for protecting metal tubular articles, particularly pipes, from corrosion comprising in order, a primer coating covering the surface of the article, an innerwrap over the primer coating and an outerwrap placed over the innerwrap, the innerwrap comprising a polyolefin layer carrying an adhesive layer on its inner surface and a layer comprising a heat fusible material on its outer surface, or a single layer comprising a blend of a polyolefin and a heat fusible moiety carrying an adhesive layer on its inner surface, the outerwrap comprising an impact-resistant polyolefin layer having a heat fusible layer on both surfaces or the inner surface thereof, or a single layer comprising a blend of an impact resistant polyolefin and a heat fusible material; the tape wrap system fusing the innerwrap and outerwrap together when heated and thereafter cooled to form a uniform, continuous and completely closed protective coating which fully protects the article against corrosion and other external d

Abstract: Novel flame-retardant conformable adhesive tapes consisting essentially of: (1) a water-impermeable chlorinated polyethylene backing layer from about 1 to 3 mils thick; (2) an evenly tearable synthetic fiber cloth or scrim; (3) a flame-retardant adhesive layer, preferably a rubber-based adhesive; and (4) a thin tie coat layer between the backing and the scrim which, when applied as a molten mass, at least partially fills the interstices between the fibers of the scrim so as to provide surface contact with the underlying adhesive layer, the tie coat providing a strong bond at both the tie coat/backing interface and the tie coat/scrim and adhesive interfaces, thereby providing a laminar product possessing the desired anchorage and structural stability and integrity.The tape is particularly useful in wrapping irregular surfaces, e.g. as a wire harness wrap, where high conformability is essential to good adhesive contact.

Abstract: Novel collapsible cores for adhesive tape rolls adapted to inhibit telescoping or migration of the adhesive tape off the roll after tape roll manufacture; and adhesive tape rolls prepared therefrom.

Abstract: Novel adhesive tapes consisting essentially of, in order, (1) a layer comprising glass or resin microspheres dispersed in a polymeric matrix; (2) a cloth scrim or reinforcing fabric; and (3) a layer of adhesive, preferably a pressure-sensitive adhesive.

Abstract: Novel adhesive tapes comprising a cloth material and a layer of plastic foam having a thin plastic skin adhered to one surface and a layer of adhesive, e.g. a pressure-sensitive adhesive adhered to the opposed surfaces; and methods for making same.
