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.

An adhesive tape characterized by having conformability rendering it adaptable for use as a harness wrap or for wrapping other small, irregularly shaped articles, said tape comprising a water-impermeable chlorinated polyethylene backing layer from about 1 to about 3 mils thick carrying, on one side thereof, a fiber woven cloth substantially evenly tearable in the cross direction; an outer pressure sensitive adhesive layer; and a thin tie coat layer positioned between said backing layer and said cloth, said tie coat at least partially filling interstices between fibers of said cloth whereby to be in contact with said adhesive layer, said tie coat providing a strong bond at the tie coat/backing layer interface, the tie coat/cloth interface and the tie/coat/adhesive interface, thereby providing a laminar product further characterized as possessing structural stability and integrity.
