Cleanly removable tapes and methods for the manufacture thereof

Abstract

The present invention provides a fire retardant, multi-layer article, comprising: a first adhesive layer comprising a pressure sensitive adhesive; a core layer having an outer surface, the first adhesive layer adhered to at least a portion of the outer surface; a fire retardant disposed in at least one of the first adhesive layer or the core layer, the fire retardant comprising a brominated phosphate and being essentially free of antimony fire retardants and polybrominated biphenyls; and the tape being cleanly removable.

1 . A fire retardant, multi-layer article, comprising: 
 a first adhesive layer comprising a pressure sensitive adhesive;    a core layer having an outer surface, the first adhesive layer adhered to at least a portion of the outer surface;    a fire retardant disposed in at least one of the first adhesive layer or the core layer, the fire retardant comprising a brominated phosphate and being essentially free of antimony fire retardants and polybrominated biphenyls; and    the tape being cleanly removable.    
   
   
       2 . The article of  claim 1  wherein the fire retardant is disposed in the first adhesive layer and the core layer.  
   
   
       3 . The article of  claim 1  wherein the fire retardant further comprises an intumescent fire retardant.  
   
   
       4 . The article of  claim 1  wherein the core layer comprises an adhesive.  
   
   
       5 . The article of  claim 4  wherein the adhesive comprises a pressure sensitive adhesive.  
   
   
       6 . The article of  claim 1  wherein the core layer comprises a substrate.  
   
   
       7 . The article of  claim 1  wherein the brominated phosphate is tris(tribromoneopentyl)phosphate.  
   
   
       8 . The article of  claim 1  further comprising a second adhesive layer, wherein the outer surface comprises a first major surface and a second major surface, the first adhesive layer being adhered to the first major surface, and the second adhesive layer being adhered to the second major surface.  
   
   
       9 . The article of  claim 8  wherein the first adhesive layer and the second adhesive layer have differentiated adhesion.  
   
   
       10 . The article of  claim 1  wherein the article is selected from the group consisting of a multi-layer tape, a multi-layer sheet, adhesive transfer tape, single-sided tape, double-sided tape, and substrate onto which the first adhesive layer has been directly applied.  
   
   
       11 . The article of  claim 1  wherein the article is a multi-layer tape and wherein the multi-layer tape has been exposed to radiation from an electron beam source to crosslink the core and/or to crosslink the first adhesive layer.
