Embodiment Construction

[0016] The adhesive composition provides an additional seal between certain components within the heat recoverable multilayer tube. The colorant associated with the adhesive composition in the adhesive strip provides a positive visual indication of the presence of the adhesive composition after the heat recovery process. In the absence of a colorant, once the adhesive composition has melted and bonded with the adhesive layer of the tube, it cannot be known whether the adhesive composition was placed. In some cases, after the recovery process is complete, it is important to know that the adhesive composition is included and in place, and has not been forgotten or omitted, intentionally or not. In some embodiments, the colorant also provides positive visual identification that sufficient heat was provided during the heat recovery process.

[0017] Such as figure 1 As shown, the multilayer tube assembly 10 includes an outer tube 12, an inner tube 14, a base 16, at least one pro...

Abstract

A process of heat recovering tubing includes forming a multilayer tubing assembly, heating the multilayer tubing assembly to a shrink temperature to form a heat-recovered tubing assembly, and visuallyinspecting the heat-recovered tubing assembly for a presence of at least one colorant. A multilayer tubing assembly and an adhesive assembly are also disclosed. The multilayer tubing assembly includes an outer tubing of a heat-recoverable material, an inner tubing of a heat-meltable material, a substrate encased by the inner tubing, at least one protrusion encased by the inner tubing, and an adhesive strip including an adhesive composition and the colorant. The outer tubing encases the inner tubing. The adhesive strip is located between the substrate and the protrusion.

Description

technical field [0001] This invention relates to adhesives. In particular, the present invention relates to indicating adhesives for heat recoverable tubing assemblies. Background technique [0002] Heat-recoverable, heat-shrinkable tubing has many different applications as protective coverings for components such as electronic, electrical, and fiber optic components. When heat is applied during the heat recovery process, the tubing contracts to contact one or more components protected by the tubing. Heat-recoverable, heat-shrinkable tubing is also capable of grading the electric field of the component when made with suitable material parameters, especially suitable conductivity and dielectric constant. [0003] Using multi-layer tubing allows different compositions to be used in different layers to provide multiple functions such as stress control, insulation and durability against environmental stress. [0004] When multiple components are wrapped by tubing, the geometr...
