Abstract
A tube assembly includes glass fiber, a heat-recovered heat recoverable tube surrounding at least a portion of the glass fiber, an adhesive having an adhesive composition comprising a reactive polyethylene and a reactive propylene copolymer. The adhesive adhesively couples the heat-recovered heat recoverable tube to the glass fiber. The adhesive composition includes a reactive polyethylene, such as, a maleic anhydride modified linear low density polyethylene resin, and a reactive propylene copolymer, such as, a maleic anhydride grafted polypropylene copolymer. The adhesive composition is capable of adhering to glass fiber with an axial load of 5 N at 70° C. for a period of at least 60 seconds.
